Biology Starter Lab Station
Ten labs for the Starter Lab Station equipment.
Grade Level: High School
Subject: Biology
Activities
01) Enzyme Action - Pressure Sensor
Students use a pressure sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
02) Membrane Permeability (pH sensor)
Students use a pH sensor to explore which substances can and cannot pass through a cell membrane model.
03) Osmosis
Students use a pressure sensor to study the movement of water through a cell membrane model by osmosis.
04) Plant Respiration and Photosynthesis
Students use a carbon dioxide gas sensor to measure the rates of photosynthesis and respiration in spinach leaves.
05) Respiration of Germinating Seeds
Students use a carbon dioxide gas sensor to explore the energy requirements of seeds moving from dormancy to germination.
06) Acid Rain
Students use a pH sensor to measure the impact atmospheric pollutants have on rainfall and plant growth.
07) Regulation of Body Heat
Students use two fast response temperature probes to look for evidence of homeostasis while experiencing changes in external body temperature.
08) Plant Pigments and Photosynthesis
In this lab, students will separate plant pigments from a sample using paper chromatography and measure the light reactions of photosynthesis using a colorimetric substitute for NADPH.
09) Cell Size
Students use a conductivity sensor to measure the effect of cell size on solute diffusion rate using agarose-salt cubes.
10) Cellular Respiration in Yeast
Students use an optical dissolved oxygen sensor and a fast response temperature probe to investigate the effect of temperature on the cellular respiration rate of yeast cells.
