Teachers, save “How strong are eggs?” to assign it to your class.

For this science experiment you will need at least 3 raw eggs, 3 caps from water bottles, a piece of cardboard and some materials to use for testing such as books, blocks, or even a container that will hold water. 1. Place each egg in a bottle cap (this will help stop it from rolling) and arrange the eggs in a triangle shape. 2. Place the piece of cardboard on top of the eggs (this will be the surface or table top used for testing). 3. Use your materials gathered for testing and carefully place them one at a time on top of the cardboard. How many books or blocks do you think the eggs can hold before they break? If using water, place the container on top of the cardboard and very slowly pour water into the container. How full do you think it will get before the eggs break? (If using water, you might want to do this in a sink or tub or on a thick towel!) Use the to post your findings for me to see! 4. What did you learn with your experiment? Were you able to break the eggs? Did they hold more than you expected? 5. Click response and use the microphone on page 1 to tell what you noticed. Note: The secret to the egg strength is the dome shape! Dome shapes are used in many buildings. Look at the examples on page 2. Have you ever seen any of those buildings or any buildings that have similar shapes? If you want, use the microphone to tell about dome shaped buildings you have seen.
