First we soaked an egg in water and one in vinegar. WE immediately noticed that the egg in vinegar floated up to the top and small bubbles started forming around the egg. The egg in water had no change.
Next, we left the egg soaking for 3 complete days. The first time we did the experiment we noticed that on the third day, the egg still had some of its hard shell. We decided to leave it for an additional day before removing it from the vinegar.
Finally, we noticed on the morning of day 4 a white film on the top of the white egg had formed and a brown film had formed on the brown egg.
The egg in water cracked immediately while the egg that was soaked in the vinegar bounced.
We predict that the reason the egg in the vinegar bounced was because vinegar has acid. That acid made the egg shell dissolve allowing the skin on the inside of the egg to form. We also observed that the egg bounced when bounced from a low distance but when we dropped the egg from a higher distance it broke on the table. This think this happened because it was falling at a faster distance because it was high.
Students learned about the different types of material objects are made of. They were given a bag of items and to select three different types of material and name. They were also asked to decide if they had to build a model house which material would they choose and tell why.
Students in Class 1-210 learned about 2-D and 3-D shapes in math. They created various 2-D shapes out of marshmallows and pretzel sticks. They were then challenged to created a 3-D home for their marshmallow bunny (during Easter time).
Students in the First grade made tools using only 1 paper towel roll, 1 index card, tape and a scissor. Students had to explain how their tool can help make a persons life easier and demonstrate.
