Math + Science + FUN!

As discussed in math class before Spring Break, students are to pick a science fair project or experiment that interests them.  The project/experiment can be as simple or as complex as they wish. Set up your experiment carefully, following the step by step process of the scientific method.  Record your results and complete your experiment multiple times, logging your data each time. Once you have completed your experiment at least 5 times, you can “do the math” and tally all of your data. 

This is where you merge the math assignment from Mrs. Raynor with this assignment. Your data will show ratios and percentages. Math + Science = FUN! (Hint—complete the experiment 10X and your math project becomes simple!)  You may present your final project in any form you choose. (Example: written report, video, poster board, photos, interpretative dance, etc.)

Here is a silly review of the scientific method we learned about at the beginning of school:

There are a plethora of resources out there, full of exciting ideas. Two resources I have found very useful are The Complete Handbook of Science Fair Projects and 100 Award-Winning Science Fair Projects.

The students will review and expand upon concepts learned in our classroom lab and put this knowledge to practical use in their home kitchen.  

The Great Egg Conundrum:

In your science notebook, review your notes about eggs and the proteins inside the shell.  Review how to separate egg whites from the yolk and why certain recipes require just the egg whites.  Write your findings below or restate them to your parents.

EggRoll: Activity #1

Materials:

— (1) boiled and (1) raw egg (make sure both eggs appear similar on the outside)

— (1) Tbsp table salt

— (1-2) cup(s) of white vinegar

— (1) cup of corn syrup

Procedures:

  1. Have someone place both eggs on a flat surface without you touching them.  Make sure they mix the two eggs up so you do not know which one is which.
  2. Have your assistant give both eggs a good spin. 
  3. Once both eggs are spinning and twirling, stop both eggs with your hands and quickly let go.  One egg should mysteriously spring back into a spin. 
  4. List your observations below and consider what a liquid and solid interior could do to the egg’s motions.
  5. Now, turn your attention to the other egg. (the egg that didn’t start spinning again when stopped) Get this egg to turn very, very fast.  Write your observations below.

Egg #1 Observations:

Egg #2 Observations:

What do you think happened to each egg and why?  How does the liquid interior change the spinning of the egg? What about a solid interior? Is the cooked egg or the raw egg the Stand-Up-and Go spinner or the raw egg and why?

Email me at chellececil@gmail.com if you need help with your answers.  

Eggroll: Activity #2

Procedures:

  1. Grab your raw egg and some table salt. 
  2. Make a small pile of salt on the flat surface and place a small pile of salt on a flat surface.
  3. Place the egg on the pile of salt with its longer axis pointed up.  
  4. Gently rock the egg back and forth until it feels stable in its upright position and then….let go! Your egg should be REMAIN STANDING!
  5. Carefully blow the extra salt away from the eggs base as it stays perched upright on a point just below its center of gravity.

Egg-cellent: Activity #1

Procedures:

  1. Stick the raw egg in a clear cup and pour white vinegar over it, completely covering the shell. You may notice an immediate reaction.  Record what you see below.  
  2. Cover the cup with plastic wrap and leave it alone for 24 hours.  Record your observations below.
  3. Carefully pour out the old vinegar and add fresh vinegar over the egg, cover it with plastic wrap and leave it alone for 24 more hours.
  4. On the third day, carefully spoon out the egg and rinse it under tap water.  Can you see the thin opaque membrane? Record your observations below.  
  5. Now, soak your naked egg in a cup of water overnight.  This step is a great example of how osmosis occurs.  
  6. Finally, place your egg in a cup of corn syrup and observe what happens to the egg. Record all of your observations below. 

Observations after 24 hours in vinegar:

48 hours in vinegar:

Observations after soaking in H20:

After soaking in corn syrup:

Reflect:

Why does the egg’s shell dissolve when submerged in vinegar?  What are the bubbles you observed when the egg is first placed in the vinegar? The answer is a gas. What gas do you think is being released?  How did the process of osmosis change the egg? Corn syrup? Can you see a small white dot inside the yellow yolk? If so, you have found the cell’s nucleus.  An egg is a great example of a single cell with a membrane and a nucleus.  

Extension Activities:

Consider: Does temperature change the rate that the acidity of the vinegar dissolves the egg’s calcium carbonate shell?  Set up a new experiment and find out.  

Consider: Do other acidic liquids dissolve the egg’s shell? Find other acids and find out. 

Lesson Three


GERM Science

6B41BF74-DB54-490A-97D3-5289CD523449

Science Objectives: The student will be able to list the four different types of germs and how they can be useful or harmful..  The student will discuss the why, when, and how of hand-washing and how this one skill is paramount to maintaining a healthy body.  The student will learn how to make several tools that are often used to ensure germs do not spread from person to person.

Lesson Four: Kinesiology with Mr. Hill, April 7th

Hello students,

We have had a year full of information in our Kinesiology class. We have explored our skeletal and muscle systems. We have also used exercise to learn more about how our bodies work. We have also discovered how nutrition plays a vital role in how well our bodies perform. We looked at the different types of food sources and how they provide our bodies with different types of fuel and nutrients to keep us healthy. My goal for this year was for you learn the basic bones and muscles of the body, along with the basic nutrients that support a healthy lifestyle.

Before my surgery and our spring break, we began to discuss the body’s muscular system. We will briefly review the main muscles of the body, what bones they support,  and how they work. Please review your notes from class and add the information you learn from the links and pictures in this lesson.
