Hormone-Induced Plant Propagation Lab using Carrot Root Cultures
Students evaluate the importance of hormones in living things. In this biology lesson plan, students experiment on carrots to differentiate how humans and plants reproduce. They collect data from experiment to answer analysis questions.
Curated OER
Dogs & Darwin
Ninth graders construct and conduct a laboratory experiment illustrating the transfer of mutations. They compare and contrast natural selection in organisms with long and short reproductive cycles.
Curated OER
How We Perceive Movement, Depth and Illusions
Students examine how depth perception works through a class experiment. They design and perform their own experiment that investigates visual illusions.
Curated OER
Mass vs. Weight
Students explore physical science by conducting a measurement experiment. In this mass lesson, students identify the differences between mass and weight and define a list of other vocabulary terms. Students utilize electronic scales and...
