Science

Make An
Egg Bounce

Materials

  • 1 Egg

  • Glass Cup

Instructions

  1. Before you start - make a guess on what your egg will look like after 2 days of soaking in vinegar! Why do you think it will look this way?

  2. Fill your glass with enough white vinegar to cover your egg.

  3. Put your egg in the glass and wait for 2 full days!

  4. Pull your egg out and notice the way it feels. Why does it feel that way?

Take Note

  • After the first hour, take note of what your egg looks like. What's happening with the vinegar and the egg?

  • After the first 6 hours, what is the vinegar and egg looking like?

  • What does it look like after a full day?

Code A Map

Materials

  • Print the downloadable sheets shown above or create your own placeholders and squares!

Instructions

  1. We're going to create a map and code directions through your house! First, determine a start point, an endpoint, and 2 detours along the way. Place a marker at each of those locations.

  2. Then place squares in a grid system throughout your house making sure to connect each of your initial markers.

  3. Now that your grid is in place, write out instructions on how to get from the start point to each detour and then to the ending point! Your instructions should read something like "Move 5 squared forward, Turn right, Move 4 squares forward, etc" to each spot.

  4. Follow your directions on your map to see how well you did!

Create A Challenge

  • To make this more challenging, use certain requirements while writing directions. Examples -

    • You can only turn right​

    • You have to turn right 3 times and left 4 times

  • You can also add in more detours!

Build A Hand Crank

Materials

  • 2 paper towel rolls

  • 1 regular straw

  • 1 bendy straw OR wire

  • Cardboard 

  • Tape

  • Something as a basket

  • String

Instructions

  1.  Start by cutting 2 notches at the top of each of your paper towel rolls. This only needs to be wide enough to fit the straw.

  2. Tape your rolls to your cardboard base. Make sure the notches are on the top and are lined up with each other and the rolls are straw-width apart. This is where the straw will sit! 

  3. Put your bendy straw inside the regular straw and tape together. This will be your handle.

  4. Determine what your basket will be. We used a piece of an egg carton! 

  5. Time to cut your string. The string lenght should be long enough to wrap around your basket plus the length of the paper towel rolls plus one inch. 

  6. After you cut your string, secure your basket.

  7. Then secure the other end of your string to the straw.

  8. Once everything is secure, place an object in the basket and wind up using your straw handle!

Safely Drop An Egg

Materials

  • Egg

  • Random materials from around the house

About

Help your egg land safely! Grab a bunch of materials that you think would help you build a contraption to save the egg from a fall. 

Take a look at the first two photos shown above. One of them made a safe landing, the other resulted in a smashed egg! Which one do you think survived the fall and why?

After you build your contraption, have an adult drop it from way up high and drop it! 

Take Note

  • What about your contraption makes you think it will land safely?

  • What was the result?

  • How will you build your next one stronger and tougher?

Math

This or That

Materials

  • Hanger

  • String

  • 2 cups

  • Scissors

Instructions

  1. Cut 4 pieces of string at least 16" in length. 

  2. Locate the center of 2 strings and twist them as shown above. This is where your cup will sit.

  3. Tape the bottom of the cup to this twist so it is secure. Bring the strings up and tape or tie them together.

  4. Adhere this to one side of the hanger as shown above. Do the same for the other cup! 

  5. Put your hanger on a doorknob or hook. Now your scale is ready!

Experiments

  • Have your parent pick one object. Search the house for an object you think weighs the same. Put each item in its own cup on your scale. What are the results?

  • Pick 2 objects on your own. Just by looking at them, make your guess on which weighs more.

  • Now try experimenting with liquids! Fill one of the cups with water. What objects do you think you would need to match the weight of the water?
