In this activity, learners discover how geologists use stratigraphy, the study of layered rock, to understand the sequence of geological events.

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

In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.

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

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

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

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 Scanning Probe Microscopes (SPM) and then work in teams using a pencil to explore and identify the shape of objects they cannot see, just as SPMs do at the nano

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

In this lesson, learners develop a robot arm using common materials. Learners explore design, construction, and teamwork, as well as materials selection and use.

In this activity (on page 134 of the PDF), learners explore reaction time.

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

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this activity, learners simulate nature's water filtration system by devising a system that will filter out both visible and invisible pollutants from water.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this activity, learners test the rate of ripening fruit and vegetables and use a chemical to inhibit the ripening process.

This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.

In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.
