Audience: Middle school

In this activity, students will observe the relationship between temperature and metabolism. The subjects for this experiment are Saccharomyces cerevisiae, one-celled organisms more commonly known as baker's yeast. By observing the presence of... (View More)

This kinesthetic activity simulates the process of evolution by natural selection. Students take on the roles of crab-like predators that exhibit one of four variants of feeding appendage: a spoon, fork, knife, and chopsticks. The simulation runs... (View More)

This activity is about the discovery of water ice on Mars. Learners will record and graph temperature data and use a model of an ice-rich and ice-free surface on Mars to examine how ice content in the martian soil would impact the temperature of a... (View More)

This is a lesson about the search for life on Mars. Learners will participate in three activities. In the first activity (Imaginary Martians) learners will compare a fictional organism with what they know about life on Mars today. In the second... (View More)

Highly productive commercial agriculture, known as industrial agriculture, is the focus of this investigation. Students will analyze and compare the inputs and outputs of industrial agriculture after reading background information, examining photos... (View More)
