This is a must-have resource with everything you'll need for studying food safety with your pupils. From handwashing scorecards and cleaning kitchen surfaces to navigating the world of microbes and food-borne illnesses,...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

Learners analyze the evolution of cultural attitudes through the lens of transportation, examining several artifacts, documents, and photographs. Topics covered include how American attitudes have influenced society's evolution into a...

Teens experience natural selection firsthand (or first beak) in an activity that has them act as finches foraging for food. Using different household items  to act as different beak styles, your little finches will collect as much...

Tamarin monkey language can be categorized by stem upsweep, duration, peak frequency, and frequency change. Although other complex terminology is used to describe the 38 calls of this species, the video is easy to follow and a...

The threat posed by super volcanoes is explored in a short video that reviews the destruction caused by Mount Tambora in 1815 and by Peru's Huaynaputina in 1600. Think it can't happen again? The narrator contends that the explosive...

Who says scientists are boring geeks? Certainly not the narrator of a short video who dishes up the scandals associated with Tycho Brahe, a Danish scientist and alchemist (now that's two labels you don't often see together) who used...

Take your class out to visit your automobile and use the tires to compute the weight of the vehicle. This is done by measuring the surface of the tire meeting the ground and the air pressure. This is a fun lesson in the relationship...

What a fun way to review the year's learning! Working in small groups, learners select a major concept covered in class then create a game about it. The type of game is up to each group, but the expectations of what should be included...

Physical or earth scientists construct this clever contraption to demonstrate how size effects frequency. Several paper rings of various sizes are taped onto a board and shaken to create vibrations. The resonant frequencies are easily...

Toss 100 pennies (or poker chips or any other two-different-sided objects) and remove all of those displaying tails. Line them up and repeat. The lines of pennies collected get smaller each time, successfully representing half-life.

How many noodles long is your classroom? Find out when engineers of all ages explore measurement through the use of pool noodles. With the noodles pre-cut to certain metric lengths, the activities could be used to introduce the metric...

By overlapping combs and window screening and by looking at a printed set of consecutively larger circles, learners observe Moire patterns, which provide a visual of what happens during wave interference. 

An illuminating activity demonstrates how interference of light waves creates a pattern. Using Plexiglas™ and construction paper, participants see rainbows appear as they twist or press against the plastic plates. After the activity, you...

Reflected waves of light move within a plane, and because of this, polarizing materials can reduce the glare our eyes see. This resource explains how to set up a demonstration of this effect. Consider it for use in your physical science...

The concepts of refraction and reflection gel with your physical science class during this colorful exploration. Shining lasers through Petri-dish-shaped gelatin desserts, they will notice how the light travels and bounces off the sides....

The inverse square law is revealed when your class participates in this activity. They move a graph paper or perfboard square back and forth in a square of light to see how the intensity changes. You will definitely want to add this...

Demonstrate lift to the class that is studying aerodynamics. In the stream of air produced by a blow dryer, little physicists place a wad of tissue paper and a spherical figure to compare. Or, if you have a vacuum cleaner and beach ball,...

Have some physical science fun when studying the center of gravity or center of mass. Simply have balancing artists stand a dowel on one finger and keep it from falling over! A lump of clay is added and moved up along the dowel over a...

If you weren't already blown away by first two installments, check out this clip on how gravity and space-time interact! Our physicist friends, Pontzen and Whyntie, continue their discussion of these motion concepts for your high...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

As physics masters view this presentation, they learn how nuclear power is used in submarines. They use Google Maps to plot a course through the ocean and calculate the time required for surfacing and traveling. They learn about fission,...

Take a look at acceleration within the context of automotive technology. They vary the mass on a toy car and run it down a ramp, exploring Newton's second law of motion. Though this is a classic lab activity, you will appreciate the...

Rise and shine! Class members collaborate to construct a photovoltaic solar cell with two semiconductor layers, as guided by this fabulous lab sheet. They test its output with an ammeter or galvanometer.
