In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

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

In this activity, learners calculate the width (horizontal diameter) of the blind spot on their retina. Learners make a blind spot tester using a piece of notebook paper.

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

Get all wrapped up in a lesson about skin!

In this activity, learners use a straight line to learn about circles. Learners measure and record the diameter and circumference of different sized cylindrical objects on a chart.

In this activity, learners discover the importance of maps and scale as they work together to create a map of the classroom.

In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this activity, learners explore Charles' Law in a syringe.

Learners explore the relationship between energy consumption, population, and carbon emissions in the countries of the Americas.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners will investigate how shorebirds and seabirds are extremely vulnerable to changes in their environment, whether human-induced or otherwise.

In this activity, learners will explore how the human brain interprets environmental stimuli.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

In this activity, learners explore the great pump in their chests--the human heart!

In this space science activity, learners explore transits and the conditions when a transit may be seen.

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

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.
