This lesson focuses on how materials behave differently as their surface area increases.

Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

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.

This activity (on page 3 of the PDF under GPS: Baseball Activity) is a full inquiry investigation into how "bounciness" relates to the distance a ball will fly when hit off a batting tee.

In this activity, learners investigate the properties of different types of balls.

In this family or group inquiry activity, learners use their senses to explore a local forest or woodland.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

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 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

This activity (on page 2 of the PDF under SciGirls Activity: Pet Handedness) is a full inquiry investigation into whether pets show a preference for the left or right paw, or “handedness” like people.

In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.

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.

In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this activity, learners construct a robot-like hand to demonstrate how data is collected when using robotic technology.

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".

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, learners stain fabrics--on purpose!

Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio.
