Become familiar with the basic concepts of inheritance. Your junior high students work through mulitple examples of crosses and calculate probabilities of trait occurance. The explain the concept that each parent contributes one half of...

In this first part of a two-part instructional activity, learners track and record the sun's azimuth using a solar panel. They graph and analyze the data to identify relationships among the time of day, the altitude and azimuth of the...

Looking for authentic hands-on nutritional experiments? High schoolers will perform experiments to test for the presence of vitamin C in several solutions as well as the effect of caffeine on Daphnia. They will also consider the...

Dispel the many myths and misunderstandings for teens regarding pregnancy. Health students discuss the reproductive system, how conception occurs, and review new information through an excellent in-class game. Some wonderful blackline...

Through two investigations, life science learners determine whether or not yeast is alive. They perform tests for metabolism by providing sugar and observing if gas is produced as a byproduct. They incubate some of the sample for at...

Though the walrus spends roughly one third of its time on land, it eats organisms that live on the bottom of the ocean. The first in a series of five, the lesson uses a variety of plant and animal cards to have scholars build an arctic...

Don't lose your marbles — you'll need them for a lesson on neurotransmission. Young scholars build a neurotransmission model using marbles, beads, rubber bands, string, and other elements. After studying specific neurotransmitters,...

Students examine organisms that are composed of tissues, organs, and systems. They dissect a fetal pig and explore the assigned organs systems such as the skeletal, muscular, and circulatory organs. Students identify and explain their...

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...

The subject of this life science reading comprehension worksheet is the excretory system. After examining the provided article, readers respond to a series of questions using evidence found in the text.

Searching for the perfect indoor/outdoor activity that allows class members the opportunity to learn about organism classification? Here, pupils research organisms and categorize them according to domain and kingdom over the course...

Addiction is a big deal! Playing a game of cards helps learners understand the concept of addiction. Through their analysis, they examine the potential for addiction and how it varies for each individual.

Most pupils know about the flu, HIV, and other viruses, but they don't know what each actually looks like. This interactive shows their relative size, structure, and allows for comparisons. It stresses the similarities and differences...
