Lesson Two

Learning Objectives: 

1. Living things can be sorted into groups in many ways.
2. Animals are grouped, or classified, by similar characteristics.

Science: How do Scientists classify living things/organisms?

Monday Biology students, K-6, have been learning about the classification of all living things.  We have started with single-celled organisms and progressed to simple, multicellular living things, and living things classified as invertebrates. The week before our Spring Break, we explored the living creatures in the phylum arthropoda.  

The next few weeks, we will be looking at living things in the kingdom animalia that are  vertebrates. We will be exploring the 5 most well known classes of vertebrates: mammals, birds, fish, reptiles, amphibians.  Next week, we will explore vertebrates in the class reptilian and list their main characteristics. I will have a live Zoom “conference” with a few of the reptiles that live at my house!

========================================================================

Activity 1

Mystery Science: How many different kinds of animals are there? 

In this Mystery, students examine how scientists organize animals into groups based on their characteristics. In the activity, Animals Sorting Game, students study animal traits and use these traits to sort animal cards into mammals, birds, reptiles, and invertebrates. Students are then challenged to make decisions about animals that don’t fall neatly into any of those categories.

Activity 2 (Geared toward younger students)

Listen to the story Never, Ever Shout in a Zoo by Karma Wilson

Animal Classification:  Many different kinds of animals live at the zoo (ask your student to list all the animals he remembers from the book).  You may want to write down the animals your student remembers. Ask him to group them in different ways (animals that can fly vs. animals that can’t; animals with two legs vs. animals with four; animals who live in water vs. animals who live on land; etc.) Tell your student that scientists have grouped animals in a special way; they’ve grouped animals based on their similarities and differences. One of these groups in the Animal Kingdom is called vertebrates. Within the classification vertebrates (animals with backbones), there are five different categories: Mammal, Reptile, Bird, Amphibian, and Fish.

Older students

VIDEO: Watch Animal Classification for Children

Animals are classified into different groups based on their characteristics. Invertebrates are animals that do not have a spine, or backbone. Vertebrates are animals that do! Vertebrates are further classified into fish, amphibians, reptiles, birds, and mammals. Come and learn what makes animals a part of these groups in this fun, kid-friendly

Lesson Four: Zoom Lesson Monday, April 6th

Lesson Five:Wednesday April 8th Lesson with Mrs. Cecil

Wednesday’s Exploration Science K-6th

Newton’s Bottle

Objectives:

–The learner will recall Newton’s First Law of Motion and be able to define the terms inertia and friction.

–Utilizing prior knowledge, the learner will hypothesize the outcome for the following experiments:

Materials Needed:

2 Glass Soda bottles

Several dollar bills, some old, some new

7-10 Quarters

Activity #1:

1.  Flatten the dollar bill onto a clean, flat surface. Place the bottle open end down in the center of the dollar bill. Steady the bottle carefully. It should be standing in the center of the dollar bill, upside down.
2.  Try to pull the dollar bill out from under the bottle without: 

1. 1. touching  the bottle  
   2. Knocking the bottle over.

WERE YOU ABLE TO PULL THE DOLLAR BILL OUT FROM UNDER THE BOTTLE WITHOUT KNOCKING OVER THE BOTTLE?

1. Now, carefully roll up the dollar bill on one end, rolling towards the bottle.
2. When the rolled up dollar bill reaches the mouth of the glass bottle, slowly nudge the bottle towards the far edge of the bill. Continue to roll up the dollar bill until it is completely out from under the bottle that is left standing alone, upside down.

CHALLENGE:

Place a dollar bill between 2 glass bottles, stacked mouth to mouth and balanced on one another.  Now, are you able to swipe the dollar bill out from between the two bottles without the bottles falling?  Does swiping the dollar bill quickly or rolling it slowly and carefully keep the bottles balanced?  What about a dollar bill that is wrinkled, old or dirty?  How does FRICTION change the results? Try other papers with different surfaces: construction paper, sandpaper, index card, cardboard.

==================================================================

Activity #2:

1. Place the dollar bill as centered as you can on the mouth of a soda bottle.
2. Place a stack of 6 quarters on top of the bill so they’re balanced directly over the mouth of the bottle.
3. Point an index finger and use it to quickly swipe the dollar bill out from between the bottle and the quarters. Be careful to not hit either the coins or the bottle.

WERE YOU ABLE TO SWIPE THE DOLLAR BILL AWAY WITHOUT KNOCKING OVER THE BOTTLE OR COINS?

CHALLENGE:

Try it again but this time use less or more quarters.  How does this change the results?  Now, see if you can balance a second bottle on top of the bottle, a dollar bill, and a stack of coins. Can you repeat the same trick without knocking everything over? Take what you know about friction and inertia and test the bill in between other identical objects stacked on top of each other. (like cups, cans, or jars)

========================================================================

NOTES (older students keep lab notes in their science binders)

1. Sir Isaac Newton’s  First Law of Motion — ____________ states an object in motion or at rest tends to stay in motion or at rest UNLESS a force acts on it to change its speed, direction, or movement.
2. _____________ is the tendency of one surface to give resistance on another object when this object moves across its surface.

1. Activity #1 demonstrates INERTIA.  But it is the ______________ of the magician’s trick of pulling the tablecloth off of a table.  In this experiment, the balanced bottle wants to stay at rest in this upside down position. Using the magician’s trick and quickly whipping out the dollar, causes TOO MUCH inertia and this force makes the bottle fall.  The key here is ___________ and __________.  The friction between the bottle and the dollar bill is strong and you need to reduce the impact of this friction by slowly and steadily rolling the dollar, making sure you use less force and the bottle will not be tipped over.  Old and dirty dollar bills are usually more crumpled and these factors increase the friction and make this experiment more difficult.

1. Activity #2 demonstrates FRICTION.  The surface of a dollar bill that is clean and smooth does not create much friction between the dollar bill and the stack of coins or the bottle below.  With very little friction, the dollar bill doesn’t pull on the coins or the bottle and they remain balanced.  Add more ______________ by using sandpaper or cardboard and see what happens.  Adding or decreasing the number of quarters to this experiment changes the force needed to whip out the dollar bill.

DRAW  your observations and results of the two experiments.

ANSWER KEY TO NOTES:

1. Inertia
2. Friction
3. Opposite, slow and steady
4. Friction

Lesson Seven: Wednesday, April 15th: Exploration Science with Mrs. Cecil

Objectives:

The student will review the definitions of force and surface area.

The student will explore how the surface area of an object can decrease the effects 

of this force. 

Materials:

Paper towel or toilet paper rolls

Tissue paper or kleenex

Rubber or hair bands

A stick or chopstick

½ cup of salt or rice

Plastic bottle

Dry rice (enough to fill the water bottle)

Experiment #1: Magic Tissue Paper

1. Place the tissue paper over one end of the toilet paper roll and make sure it is as flat as possible. Carefully, hold the tissue in place with a rubber or hair band.
2. Try puncturing the tissue paper using your wooden stick. How easy was it?
3. Place a new piece of tissue paper over the end of the toilet paper roll and hold it in place with your band, the same as before.
4. Set the toilet paper roll, tissue side down, on a flat surface.  Make sure the tissue and roll are flat.
5. Pour salt, or whatever you want to try, into the toilet paper roll until it is 3/4-full.
6. Lightly tap the toilet paper roll on the hard surface to help pack the salt.
7. Now, try to push your stick through the tissue paper on the end. How easy is it now?!?

Challenge:

Try different materials in the toilet paper roll such as rice, baking soda, gravel, 

sugar, beads. What works best? What doesn’t work?

Try different lengths of tubes.  Does the length of the tube make a difference?

Try different types of thin papers, like toilet paper or paper towels.  Record your observations below:

Experiment #2:  Floating Rice Bottle

1. Fill a plastic bottle up with rice but stop about an inch from the top. 
2. Put the lid on the bottle and shake it to fluff up the rice, until it looks nearly full.
3. Now, put your stick or chopstick in the center of the bottle and CAREFULLY lift.  Careful, it will make a mess!
4. Now, you want to put some extra rice into the bottle. To make room for the extra rice, tap the bottom of the bottle on the table. Add more rice and continue to tap, until all of the space is taken up by the rice. 
5. It is time to try to lift the bottle again.  Put your stick in the bottle this time and carefully lift the bottle up by the stick.  It should “stick” to the rice well enough to lift the bottle. 

Challenge:

Try different sizes of sticks and bottles. 

Try different amounts of rice in the bottle. What is the least amount of rice that you can use and still make it “stick?” Is there a point where there is too much rice?                                                                                                                    

Try different types of objects. Do pebbles or sugar or salt work the same way? Record your observations below:

Download notes to print!

Notes for Experiment #1:

1. I bet it was obvious to you that the wooden stick can easily push through a piece of tissue paper that’s wrapped around a cardboard tube.  Remember, FORCE is a ___________ or ___________ on an object that can cause the object. 
2. But, what changes when you add salt to the tube? The amount of _________ you use to push into the tube remains the same. I bet you even add even MORE force into the tube once the salt is added to try to break the tissue!
3. Does the salt give the tissue magical hero strength?  ______________
4. The key to the tissue paper’s sudden strength is the addition of salt. BUT WHY? Any guesses why salt appears to make the tissue super strong? ____________________________________________________________  
5. The tiny grains of salt add one special “trick” we have learned about before.

Two words: _____________ __________

1. SURFACE AREA is the measurement  of the outer areas a solid object has around it. Basically, it’s the surface or ____________ of any object, all of the way around it. Think of a cube and how many sides it has.  
2. The ¾ cup of salt we poured into the tube is made up of thousands of salt grains. We could not count them all!   All of the force of you pushing the stick into the tube spreads from grain to grain of salt and against the outside of the tube. The force is also spread across the entire area of the tissue paper, instead of just one small area of the thin tissue paper. The _______________ surface area of all of the salt makes the tissue paper appear magically stronger!

Draw a PICTURE of experiment #1  below: 

Notes for Experiment #2

1.This “magic trick” dates back thousands of years.  But it isn’t really magic, it’s 

just __________________. 

2. Inserting the stick into the bottle of packed rice, takes up additional space. 

Rice is not a fluid, so it can not be as easily displaced as fluids can.  

Remember, DISPLACEMENT is the __________ or ____________ of an object, usually a fluid, that is pushed away and equals the amount of the object that replaced the object or fluid.  (Remember, Eureka?!?) The rice is packed in so tightly that there is little room to move so it presses against the sides of the bottle. The stick is wedged in between the tiny spaces between the individual pieces of rice. 

3. As you tap the bottle, you are packing down the rice, filling in spaces that are not really “empty” in between each grain of rice. The spaces that look 

empty really have __________ in the small spaces between each rice 

grain.  

4. Our friend, and sometimes enemy, _____________ helps hold the stick in the

bottle as it is lifted in the air.

Lesson Nine: Wednesday, April 22nd with Mrs. Cecil

Exploration Science

Objectives:

         The students will explore the physics of balanced forces.

The students will discover how laws of geometry and physics work together to          balance the forces of gravity and weight.

Materials:

            3 glasses or glass bottles or jars

            3 butter knives

            Drinking glass or container

            Water

            Several pieces of light weight printer paper

            A book or two

            A rubber band

            Other Non-breakable objects

Experiment #1:

1. Place three glass soda bottles or containers at an equal distance apart, in a triangular shape.
2. Now, add the butter knives, making sure the glass containers or bottles are close enough to one another so that the blade of one knife lays atop the handle of another.
3. Gently, rest the knives on top of the bottles, placing the handle of the knives on the open end of the glass container or bottle. The knives will stay interweaved and balanced.
4. Set a drinking glass on top of the very center of the knives. The cup should sit balanced and steady.
5. Pour water into the drinking glass to check if your design is balanced.
6. Draw a picture of your structure below:

Challenge:

Try this with other objects.  Will forks or spoons work?  What about different sized glasses or containers?  In a safe place (not near your paperwork or computer!)  try adding more water to the middle container.  Does the weight of the center container change the balance?  How can you make this experiment more difficult?

======================================================================

Experiment #2:

1. Apply what you have learned about balancing forces.  Do you think you could balance a book on a rolled up piece of paper? Try as many ways as you can think of to make the paper “stronger.”  Remember our last few experiments and how we made things appear to be stronger by distributing the force and maintaining balanced forces.
2. Now, roll the paper into a tall cylinder, side to side, and wrap a rubber band around the tube to keep it in place.
3. Can you balance the textbook on top of the paper cylinder now? What made the difference?
4. Find other items to balance on top of your powerful tower or paper.  Make sure you only add items that are not breakable!
5. How many items were you able to get on top of your paper cylinder before it was crushed under the weight of the objects? If you have a scale, weigh the items you added.  If you don’t have a scale, make a see-saw balance to weigh your objects.
6. Draw your experiment below.

Challenge:

            What other shapes have “super powers?”   Can you list other geometric shapes that have super strength?  Test out other shapes and experiment with balancing forces.  You are expanding your knowledge of physics and geometry!  What if you change the type of paper you used?  Would thicker paper add more strength?

Lesson Eleven: Wednesday, April 29th with Mrs. Cecil

Wednesdays–Exploration Science

Objectives:

The students will build on their knowledge base for Newton’s first law of motion.

The students will explore the differences between the “twin forces”–centripetal 

and centrifugal forces. 

Materials:

A wire coat hanger

A penny

2 clear, plastic cups

Hot glue gun or strong, clear tape

2 lightweight ping-pong style balls or other identical round objects

A pencil or another object you can use as a “handle”

Experiment #1:

1. Bend the hook portion of the wire hanger until the end is pointed back in the opposite direction.
2. Stretch the hanger until the hanger is diamond shaped with the hook at the bottom end. 
3. Balance the penny on the hooked end of the hanger.
4. Begin to swing the hanger back and forth. Use a very small amplitude (swing height) at first and gradually increase the swing until you can spin it in a full circle.

Here’s a link with step by step visuals for this experiment:

Challenge:

Try using other coins or objects.  What if you didn’t bend the wire hanger?  Will a plastic hanger work? What objects can you swing in a circle and hold them in place?

Experiment #2:

1. Place your lightweight objects like ping-pong balls inside your two plastic cups. I added color to the balls so we could see what happens more clearly.
2. Use your clear tape or hot glue to seal the cups together, mouth to mouth, so that the balls are sealed together inside.  
3. Glue or tape your “handle” to the middle of the cups at the point where they meet, mouth to mouth.  You may have to add extra tape or glue here so that the handle stays in place at the center.  
4. Holding your cups by the “handle” spin them and see what happens to the balls inside.  Explain what happens and why.

Here’s a link with step by step visuals for this experiment:

Challenge:

Will this work with ALL objects you place inside?  Does the size of the cup matter?  What if the weight of the objects inside were of different weights? Test your theories and write your observations below: 

Notes for Experiments:

1. According to Newton’s first law of motion, objects in motion tend to stay in motion unless acted upon by an external, or outside, force.
2. Newton’s law requires the penny to continue moving along its path to the circle.  A force is required to keep it always turning toward the CENTER of the circle. This is often confusing when one considers that at the top of its arc, the penny is accelerating downward because of the motion, but that the force of gravity is also downward. So, how does it stay in place? 
3. Main idea–Centripetal force is the INWARD force that keeps the moving in  a circular pattern towards the CENTER of a circle.  
4. Centri means “center” movement.  The circular movement forces objects  INWARD to the center, or radius.  THINK ABOUT SITTING ON THE INNER CIRCLE of a merry-go-round.  
5. Centrifugal force isn’t really a “force.”It means “center FLEEING.” It is an OUTWARD pressure the object feels as the object is moving in a curved path, AWAY from the center of rotation. THINK ABOUT SITTING ON THE OUTER EDGE of a merry-go-round. 
6. Diagram of riders on a merry-go-round:
7. Merry Go Round
8. Both centripetal and centrifugal forces work together to keep the object moving at a steady speed in a CIRCULAR path.

6. Let the bag burn completely to ash and watch as it lifts off the surface and rapidly rises into the air.  As the bag cools, it will lower back onto the surface.  Take note of any material that remains and describe what you see:_______________________________________________________
7. Draw a PICTURE or your experiment below:

NOTES:

1. There are three principles that make your great teabag lift off:

1.   There’s the density difference between the air inside and outside the cylindrical shaped tea bag. As the flames move down the bag, they heat the air trapped inside. Remember, heated molecules move ________________ and spread out inside the tea bag.  These molecules are much farther apart than those outside the tea bag where there are cooler molecules.  The air INSIDE  the tea bag is less _________ than the air outside. Remember, warmer, less dense air rises above cooler, denser air.
2. The burning bag generates hot, less dense air inside it and above it. This leads to a “thermal” or a convection current of rapidly rising hot air above the flames. THINK, HOT AIR BALLOON.  The space inside the tea bag must be filled so the cooler, ________ ________ air outside of the burning tea bag rushes in from the bottom to fill the space under the heated air.
3. As the bag burns, it changes into ash and smoke.The hot smoke rises, lifts away, and disperses into the air. Remember: GAS ALWAYS tries to escape and spread ___________.  A thin, fragile outline of the tea bag is all that remains. Because it is so lightweight, the force of the rising, hot air is strong enough to quickly lift it upward. As it rises, it cools and then falls back to the surface.  

1. What objects can you think of that scientists utilize that follow these three principles? ______________________________________________________________________

Challenge:

Does the shape of the tea bag matter?  Try tea bags not in a cylindrical shape. Research how rockets and hot air balloons work and write a bit about it below:

Experiment #2: Matchstick Merry-Go-Round.

1. Lay one nickel on a flat surface and balance the other nickel on top, vertically. 
2. Carefully place a matchstick across the balanced nickel.
3. Place a plastic cup over the matchstick and nickels.
4. Blow up your balloon. 
5. Quickly rub the balloon against your shirt or hair to generate static electricity.
6. Rotate the balloon around the outside of the plastic cup.
7. What does the match do? _____________________________
8. Draw your experiment below:

Notes:

1. What science principles make the matchstick rotate? ________________ and _________________

1. When you rub the balloon on your hair or fabric, you give the balloon additional ______________, generating a negative static charge. The match has a ___________ charge.
2. When an object has a _______________ charge, it will repel the electrons of other objects and attract that object’s protons. When the neutrally charged object is lightweight, the negatively charged object will attract the lightweight object, making it try to follow the negatively charged object until it loses its charge.  
3. Will this experiment work without the nickels? _______ Why or why not?__________________________________________________________________

Challenge:

Try changing the amount of time or speed in which you rub the balloon.  Try different objects to rub your balloon on.  Which objects give you more and less static electricity?  How far away can you move the balloon from the cup and still get the match to spin or how quickly can you make the match spin without it falling off of the balanced nickel?

Lesson Fourteen: Monday, May 11th with Mrs. Cecil and Tuesday, May 12th with Mrs. Haker

Monday with Mrs. Cecil:

Monday, Part 2

Tuesday with Mrs. Haker

REMINDER:

This week, present an animal to the class.  This living thing can be a vertebrate or an invertebrate.  It can be your favorite animal or a living creature you have learned about.  Challenge yourself to find out something new about the living thing you choose and present this to our class this week.

Remember to find out your living thing’s scientific name and some interesting facts about it.  Be sure to find out in what Class or Family your living thing belongs.
Think of a fun way to share your living thing with everyone in class.  A picture, a video, a living example.  (Hey, some of you may actually have a pet echidna or rhinoceros!)

Science is FUN!
