April STEM

For our April STEM project we did two activities a plastic egg stacking challenge and a whole class experiment. For our egg stacking challenge students were divided into 3 teams each team was given 100 plastic eggs. Then the teams had to stack the stack the plastic egg halves to see who could build the tallest tower. All of the students thought this would be our easiest STEM challenge yet. They were proven wrong once we started. Keeping the eggs from shifting and teammates from bumping the growing towers proved to be more difficult then originally thought. Each team was given 3 attempts at building their towers. We ended with the following heights 13in, 12in, and 6in towers.
As a whole class we predict which of three liquids would dissolve a Peep's marshmallow bunny quicker. The predictions were water-2, pop-7, and vinegar-8. Mrs. Mills, Mr. Hoyt, and myself also joined in on the predicting. It took us 3 days of soaking before we had a clear winner. And, our winner was VINEGAR! Though we found that pop was very good too, which is why it took us three days before we could declare the winner.

As I mentioned above vinegar was the winner in both the predictions and the actual experiment.
Unfortunately I forgot to take a photo of our final results. I can tell you that the vinegar bunny was the mushiest and his ears had started to completely disappear.
