In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

This activity offers learners and their families several ways to raise their awareness together about home water.

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

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

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.

In this outdoor activity/field trip, learners investigate the special shapes, holding structures and holding behaviors that real organisms use in streams, rivers, creeks or coast intertidal zones to a

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.

In this activity, learners discover why only some types of plastic can be recycled.

In this outdoor simulation game, learners search for pretend animals called "sticklers" to determine and map where they live (habitat) and how spread out they are in that area (distribution).

As a group, learners consider sources of water pollution to understand where pollution starts and where it ends up.

Build a fruit fly trap out of a 2-liter plastic bottle and some rotten fruit! Fruit flies are easy to catch in warm weather. Once you catch some, you will be able to see their life cycle up-close.

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this creative outdoor activity, learners invent populations of make-believe organisms and then investigate real populations living in the activity site.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
