In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

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 explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

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

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

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

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.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.
