This Week's Science ... WATER!

This week in science we are talking about water. The kids had different labs this week dealing with water. Their first lab dealt with buoyancy (buoyancy was our word of the week!) and seeing what types of objects will float and sink in water based on their density (another word we learned). Monday we made our predictions.

We went one row at a time talking about the pictures and what we thought would happen. The kids even wanted specifics as to what type of pen, if the rocks were from the playground or volcanoes and if the balloon was blown up or not!

Tuesday, we tested our predictions and recorded our results.

 Students noticing refraction (discussed during light energy).

We discussed the importance of going one object at a time, and recording the results as soon as they are found and not trying to go back after doing them all at once.

At pink group, they took turns testing objects and recording data then sharing with the group. Everyone tested and everyone recorded, not just one person and copying.

After all of the groups did their experiment, we went over the results as a class to make sure everyone had the same results of the lab. The reporter from each group told us their findings and we discussed which objects were more buoyant that others.
