Students explore the significance of a resting and an active heart rate. In this heart activity students chart data on their pulse and draw a diagram of the heart.

Students discover through this activity that all organisms are composed of water. They find that 70 percent of their bodies are made up of water that is in thier cells and blood, and not free-flowing throughout their body.

Fourth graders study the parts of the human circulatory system and how they function. They design a flow chart of the circulatory system and use data to construct charts and graphs.

Students investigate how earthworms help build good soil. They examine the worms carefully to find the ringlike segments and swollen band at the front of the earthworm's body. Students take turns dampening the soil every day and adding...

Create a neuron frenzy as your pupils play the part of the neurons. An engaging lesson plan creates a human chain of neurons that pass cotton balls posing as neurotransmitters. Scholars learn about pre- and post-synapses as they...

Students identify an animal and a body part and then matches a body part to a specific animal. This will assess their ability to sort organisms and objects into groups according to their parts and describe how the groups are formed and...

Students examine antigens including ones found in humans.  In this immune lesson students complete several experiments in relation to antigens and antibodies.

Students collect and graph data and use the internet to research the skeletal muscles.

This is your brain on drugs ... literally! Your neuroscientists-in-training examine the evidence of drug use on the human brain and how neurons change their connectivity when altered by drugs. They then work together to create testing...

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.

In this biology instructional activity, students identify and locate various vocabulary terms related to the science of biology and anatomy. There are 10 biology terms located in the word search.
