In this outdoor activity, learners design devices that will catch prey or gather plants.

In this outdoor activity, learners turn the fun of feeding wild birds into an investigation of bird behavior.

This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.

In this life science activity (page 8 of the PDF), learners explore the carbon cycle by mixing yeast, sugar and water.

In a series of three experiments, learners explore the basics of biotechnology using self-locking plastic baggies. Each experiment demonstrates a phenomenon or principle of biotechnology.

In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.

In this activity, learners stain fabrics--on purpose!

In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

In this set of outdoor games, learners play the role of monkeys that are trying to get enough resources (food, shelter, and space) to survive.

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

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this math activity, learners use a variety of sensory modalities to gain experiences with identifying, describing and creating repeating patterns.

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.

In this four-part laboratory exercise, learners investigate properties of Tobacco mosaic virus (TMV) including (1) symptoms induced by the virus in susceptible plants at the macroscopic and microscopi

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.
