Homeostasis, Negative Feedback, and Positive Feedback
So many bodily activities depend on homeostasis! Give learners a solid background to understand the basic process of the human body. Scholars first examine negative feedback loops contributing to body temperature regulation and then a...

Comparing Pulse Rates
Students participate in a lab that demonstrate one example of how the human body maintains homeostasis. Students collect data from themselves and observe how their own bodies react to exercise.

Makes Me Sweat
Never let them see you sweat ... unless you can't help it! Scholars design an experiment to determine the effects of stress on the body. They monitor sweat production under different conditions and relate the response to the function of...

Mindflex Activity
Control a ball with your mind! Using a headset with an electrode, learners adjust the movement of a ball. They develop an experiment that tests the involvement of the central nervous system in controlling the ball. The activity helps to...

Cardiovascular Homeostasis
High schoolers develop and conduct an experiment to answer the question," How does cardiovascular exercise affect the pulse rate?". They record the changes to heart rate during different levels of exercise.

The Effect of Temperature on Cricket Chirping
High schoolers examine the effect of temperature on how often crickets chirp. In groups, they complete the experiment and answer lab discussion questions. They create a graph of temperatures and the amount of chirps and discuss the results.

Relating Structure to Function in Cells
Twelfth graders investigate specialized structures in both plants and animals. They relate structure to function, as they determine why the specialization is necessary and useful to the living organisms involved. They use microscopes...

Blood Business
Students identify the different kinds of blood. In this biology lesson, students investigate the antigens, agglutinins and Rh factor using their own blood. They use Punnett squares to predict blood type of offspring.
