How do you calculate your Body Mass Index, and why is this information a valuable indicator of health? Class members discover not only what BMI is and practice calculating it using the height and weight of six fictitious individuals, but...

Does matter really matter? Properties of matter are discussed by Sam and RJ: mass, volume, and density. They differentiate between mass and weight. They explain how to measure these properties. Make sure to teach your class about other...

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...

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,...

Too much material will weigh you down. The sixth segment in a series of 22 highlights how weight affects a plane. Pupils learn that engineers take the properties of materials, including weight, when designing something. 

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Planning a unit on simple machines? Save some time and energy with this collection of lessons and activities that explores how these devices are used in the real world to make life a little easier. 

Some consider physics the branch of science concerned with using long and complicated formulas to describe how a ball rolls. This presentation, while long, is not complicated, yet it covers rolling, falling, and more. It compares vectors...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting instructional activity, scholars explore buoyancy and the properties of air and water. They test...

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Conversion immersion — it's measuring mania! A set of four activities teaches scholars to convert between customary and metric units. Resource covers unit conversions in length, temperature, weight/mass, and volume.

Let's talk torque! Science scholars evaluate experimental setups during an interactive from the Rotation and Balance series. Individuals calculate the torque of differently arranged weights to determine the effect they have on a balanced...

Viewers learn to recognize direct and inverse relationships in the world of physics with a presentation that reveals how to recognize a direct versus an inverse relationship from a formula or graph. After showing basic examples, the...

Do your young physicists get a little unbalanced when it comes to talking about torque? Scholars examine the effects of weight and distance on a balanced system with a simple interactive from the Rotation and Balance series. The resource...

Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

Teens often display potential energy in class and kinetic in the hallways. This third presentation covers the six types of energy, each in potential and kinetic form. It also covers the Law of Conservation of Energy and Einstein's...

Is your class struggling with Newton's Second Law? Then show them a presentation that covers everything physics scholars need to know about forces. Starting with gravity, the slides focus on Newton's Laws of Motion, and end with an...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Studies show that obesity is now a global problem. But how are researchers measuring obesity? Young scientists investigate the myriad of methods for measuring body fat through a presentation. From hands-on to high-tech, viewers learn...

The tension of the 236 strings in a grand piano exert a combined force of 20 tons on the cast iron frame. The presentation includes topics such as work, forms of energy, conservation of energy, gravitational and elastic potential energy,...

Force acts on objects in mysterious ways ... until now! A comprehensive presentation explains the balance of forces acting on objects. Learners draw free body diagrams to show these invisible forces and make force calculations.

Is obesity a disease or just a preventable risk factor for other diseases? Scholars attempt to form their own opinions by reading a background of the issue and watching videos that explore the main pro and con arguments using an included...

Direct your young mathematicians to a resource on direct and inverse variation. A video first reviews concepts on direct and inverse proportionality. Individuals then answer a set of questions in pure and applied mathematics...
