Ms. Hamby’s Biology class discover what’s in their food.

Students in this macromolecule lab were testing common food items to see which biological molecules (fats, carbs, or proteins) were present in them. Many were surprised to find that sugar, a carbohydrate, was added to many common foods they consume.

Ms. Khazaw’s Biology class learns about enzymes!

Students in the Biology Lab measured the time it took for a disk of filter paper soaked with varying concentration of the enzyme catalase (potato extract) to float to the top of a cup filled with hydrogen peroxide. The disk will float as oxygen produced in the catalase/hydrogen peroxide reaction accumulates under the paper disk.
Students in the classroom demonstrated enzyme reactions and the environmental variables that affect these reactions. They used pennies, masking tape, ball, and stop watch to investigate how enzymes work and what factors could denature the chemical reactions.

 

Ms. Hamby’s class studies the properties of water.

Students worked on four different labs to study the properties of water. In the one with food dye, they were studying capillary action. In the one with pennies and a water dropper, they were studying surface tension. In the one with the rainbow jar, they were studying the densities of different liquids. In the final area, they were researching all properties of water. They were studying water in biology due to its importance in life and life processes.

 

Students worked with non-pathogenic E. coli bacteria and performed a guided inquiry-based laboratory investigation. The laboratory activities were done in a teaching lab that is used for Biology Laboratory and Introduction to Microbiology Laboratory classes, which utilize several types of bacteria.  More pictures are available here.

Physics students learn about Newton’s Law

GHS Physics students design and build a self-propelled vehicle made of simple materials that will travel at least 5m along a tile floor, carry and egg and stops before it hits a wall.
