2nd Grade Science — States of Matter


2nd grade science 1

In Science, 2nd grade has been working on the states of matter – solids, liquids, and gases. In one of the activities, they were doing an introduction to what happens to some forms of matter when they go through a chemical change.

Ms. Stephanie explained that when you pop the top on a bottle of soda, the initial “whoosh” is from the release of the gas carbon dioxide as it leaves the container.

Next the students tested multiple hypothesis to see which combinations of matter would create the largest chemical reaction thus the ‘explosions’ in the pictures.  Students made predictions, observations, and then reassessed during their post investigations at the end in their Science Notebooks.
