Sorry for the delay in posting for awhile. It has been busy in and out of the classroom. Our Egg-ceptional Experiment ended last week with some colorful eggs. We soaked them in water dyed red which turned the eggs red and then turned around and placed these red eggs into clear water...the result is in the picture above. Great, great experiment for learning about osmosis. BTW...we started with 5 eggs and finished with 3. Thankfully they broke on the table!
Our praying mantis passed away. The kids were shocked that I just threw it in the trash...I think they were wanting a funeral with burial. Well, the mantis left us with a gift...an egg casing (ootheca). We researched that we could be expecting babies at the end of March. I've also read that it might be empty if there was no mate. Wait and see I guess.
The 5th and 6th graders finished the day on Thursday by making elephant's toothpaste. It was a reaction involving hydrogen peroxide, yeast, dish soap, and food coloring. The 5th graders are learning about physical changes and chemical changes.
