In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

In this activity, learners investigate the sense of hearing and plan and conduct their own experiments.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity (page 37 of the PDF), learners observe, on a prepared slide, muscle and spinal cord cells from a rat.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien
