In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site.

Learners develop an understanding of air pressure in two different activities.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

In this geography investigation, learners use a nighttime satellite image to observe areas of light across the United States and to identify patterns and spatial distributions of human settlements.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.

This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

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

April showers bring May flowers, but what do coastal storms bring?

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

In this environmental engineering activity, learners build windmills using everyday items. The first challenge is to build windmills that spin when placed in front of a fan.

In this activity, learners investigate the food, water, and space needs of common livestock animals.

In this activity, learners use maps to locate the Arctic region and use a word game to discover the types of resource people need to survive in the extreme climate.

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.
