Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

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 two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

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 physics activity, learners will explore buoyancy.

In this nutrition activity (page 3 of the PDF), learners will record their food consumption for one day, and then evaluate how their actual diet matched up with the recommended diet.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

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

Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

In this activity, learners observe colors in the flame of a burning candle to explore connections between matter, light, color and temperature -- basic concepts of matter and energy.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

In this activity about vision and optical illusions, learners conduct a simple test to demonstrate how our eyes create "afterimages." Learners stare at a black cardboard bat for at least 30 seconds an

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.
