In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this activity, learners use squares to figure out how many border tiles are needed to enclose different areas.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

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

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity (on page 2 of the PDF under GPS: Biodiversity Activity), learners will pair up and take a notebook outdoors to a selected location to observe and record a list of living things that t

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this indepth hands-on activity, learners build a structure that allows them to observe the growth of roots and the correlation between root growth and stem extension.

This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing

In this activity, learners conduct a scientific investigation involving decomposition and discover that the life cycle of trash is affected by its organic or inorganic nature.

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