In this activity, learners use multiple thermometers, placed at different angles, and a lamp to investigate why some places on Earth's surface are much hotter than others.

Fat is a very important component in our diet. It's the most efficient source of energy in our bodies, and plays an important role in the flavor of foods.

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

In this experiment with planaria (a type of flatworm), learners will investigate the capability of different body sections to regenerate.

This lab activity has learners create a pendulum with a one-second period.

In this outdoor archaeology activity, learners use mathematical skills and scientific inquiry to generate and process information from their own excavation site.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

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

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

In this activity, learners will perform various investigations to understand the vestibular-ocular reflex and learn about the importance of visual cues in maintaining balance.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

In this activity, learners will be introduced to biomass gasification and will generate their own biomass gases.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.
