In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this design challenge, learners will engineer a structure and see if it can survive an earthquake they create.

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

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners build a sled kite that models a type of airfoil called a parawing.

In this activity, learners explore how salt water freezes in comparison to fresh water.

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.

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

In this experiment using sprigs of Elodea, learners will observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere.

In this activity, learners model erosion using a clear shoebox and sand or soil.

In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.

In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this robotics activity, learners drive a remote-controlled car through a course to learn the challenges faced while trying to operate a planetary rover.

In this activity, 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 hands-on art and science activity (page 4 of the pdf), learners brainstorm and discuss how humans use wetlands, then express their understanding of the subject in artwork.
