In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

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.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos

Get all wrapped up in a lesson about skin!

In this activity on page 5 of the PDF (Plants—The Green Machines), learners use chromatography to separate and identify pigments within various leaves.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

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

Learners construct a bird feeder from re-used materials. After hanging their feeder, they keep a journal about what birds visit the feeder.

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

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

In this laboratory activity, learners use a simple procedure to bait oomycetes from water and/ or soil and then examine these fungus-like organisms with the microscope to see how they look.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.
