In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.

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 about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.

In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

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

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

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 team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF).

This is an activity (located on page 3 of PDF under Hockey Sticks Activity) about composites, materials made of 2 or more different components.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

This activity (on page 2 of the PDF under SciGirls Activity: Extreme Sounds) is a full inquiry investigation into sound.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this math lesson, learners explore polynomial and rational function patterns.
