Chemistry Class - reactions

This week we looked at how molecules act when introduced to other molecules.  They always follow the rules, and sometimes a reaction will occur.  The girls enjoyed their lab this week where we were able to observe some reacions occurring.

First they made observations of the liquids being used (lemon juice, vinegar, milk, baking soda solution)...

Then they predicted what would happen...

lemon juice mixed with milk formed particles of curdled milk...

lemon juice mixed with the baking soda solution made many bubbles...

after the "bubble explosion" Allie was a bit apprehensive to do any more mixing...

vinegar mixed with baking soda made more bubbles...
