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 engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

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

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

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.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

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

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".

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

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

This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

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

In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

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

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