This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

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.

In this environmental health activity, learners investigate their own vital lung capacities.

In this activity, learners dissect a piece of pizza to learn about nutrients important for health.

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

In this botany activity, learners will create an experiment about seed germination. This activity gives students an opportunity to explore how seeds germinate and react to surrounding conditions.

In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.

Learners cut out pictures of continents and attempt to put them together to form Pangaea, the supercontinent present on the Earth approximately 300 million years ago.

In this activity (page 37 of the PDF), learners observe, on a prepared slide, muscle and spinal cord cells from a rat.

In this activity, learners conduct an oxidation experiment that turns old pennies bright and shiny. Learners soak 20 dull, dirty pennies in a bowl of salt and vinegar for five minutes.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.

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 use simple items to construct a device for indicating air pressure changes.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

In this activity, learners discover how their heart rate changes in different situations.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.
