My kindergarten scientists are studying farm life, so it was a perfect time to have an egg lab. We identified the parts of an egg and saw the difference between raw and boiled eggs.

We placed an egg in vinegar. We hypothesized what might happen to the egg. We immediately saw bubbles. We’ll check this investigation next week.

Why does the egg sink in fresh water and float in salt water?

If you squeeze an empty water bottle and then let go of the squeeze over an egg, you can suck the yolk into the bottle and separate it from the white. It works like a pipette.

How did the hard boiled egg fit inside the bottle? This investigation involved fire!

Try spinning a raw egg and a hard boiled egg. Why is there a difference?

We recited “Humpty Dumpty” and discussed why he might be on the wall and what might have made him fall. Then we discovered a way to make a raw egg stand. This took patience!

Watch this video to see some of the investigations we did and some others you can try at home.

My PreK scientists created a chemical reaction and explored color mixing as they dropped colored vinegar onto plates of baking soda with pipettes. I gave them the primary colors (red, yellow, and blue), but they made the secondary colors. The children loved observing the bubbling eruptions that result when baking soda and vinegar are combined. We had lots of fizzy fun!

I was able to laminate the long snake skin I received last spring. I hung it on a hook, so we can turn it over. I have received three snake skins this week! I plan to laminate another, so we can compare them. We will also look at them under microscopes. It would be fun to do some rubbings too!

I am slowly building an outdoor science area. I placed two bird feeders, a suet feeder, and a hummingbird feeder next to the birdbath gifted by the Girl Scouts. Today’s addition was a hummingbird swing that was a gift from Mrs. Daniel. Mrs. Harwell’s class sees humming birds throughout their day. Next up is a birdhouse.

Teachers always get excited about school supplies. I saw these name tags this summer and just had to have them for my scientists! Notice the cross in the test tubes and flasks. They are perfect!
