Higgins Holds Biology Lab

Mrs. Higgins 4th period AP bio students recently performed a lab that tests the amount of gas a yeast mixture produces. They were asked to put hydrogen peroxide and yeast in a test tube and found out how much of the oxygen was in the mixture produced.

Junior Jackie Crews measured out the hydrogen peroxide in the lab.
Seniors Elijah MacDonald and Caleb Jones filled the test tube with the yeast mixture.
Senior Amanda Bowles pushed the yeast mixture into the water.
Senior Michael Hannon and Junior Clara Henderson filled the test tube with water and put it on the stand.
Senior Emma McCrary recorded the oxygen level after one minute.
Senior Haley Cox watched the oxygen rise into the test tube.
