So Many Eggs!
With spring here and Easter approaching, use this time to study oviparous animals and perform egg investigations. My science students hatched chicken and duck eggs in the science lab. Click here to watch a video of our chicks hatching and here for a video of the ducklings.
I watched robins hatch on a window ledge at home.
But birds aren’t the only ones who lay eggs; both my aquatic and terrestrial snails surprised us with eggs!
We also watched praying mantids hatch from their egg case.
Turtles lay eggs too!
Have you ever seen frog or

Try the following lively investigations and experiments that can be performed at home or in a classroom:
Identify which egg is hardboiled and which is raw by spinning them and squeeze an egg without breaking it!
Make an eggshell disappear! (A favorite!) Click here for directions.
Knock eggs in water using inertia. (I practiced with golf balls.)
The egg in the bottle was always a crowd pleaser in my science lab! I used “milk” bottles that I purchased at Michaels.
Use eggs to teach the importance of brushing your teeth. Click here for additional information.
Demonstrate the power of air pressure and separate the white from the egg yolk. Squeeze the air out of an empty water bottle and place the opening of the bottle over the egg yolk, still squeezing. Slowly let go of the squeeze and watch how the yolk is sucked into the bottle. It works like a pipette.
Use After the Fall as a springboard for an engineering activity. Task your students with devising a way to help an egg balance on a block wall without falling off or for the popular egg drop challenge. Click here to view full screen.
My youngest scientists tried to make an egg balance using salt which required perseverance!
