Lab

Yesterday, we did a lab experiment in biology class. First we created a gel mold and placed it into buffer. Then we injected different chemicals into each square in the gel mold and turned the electricity. The chemicals moved either to the rite or to the left, determining if it was positive or negative charge.

Snail Experiment

we observed the reactions of vinegar on snails and viewed the bottom of the snail when they moved across the lens. While moving across the lens, we could see the wavey patterns underneath the snail's body.
