In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this multi-part activity learners examine non-point water pollution.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.

In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

In this activity, learners participate in a scavenger hunt, searching for and recognizing minerals and products that contain minerals.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

In this engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners explore the possibilities of clay as a natural material.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

In this activity, learners explore clouds and how they form.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

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

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
