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...

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. 

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...

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,...

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.

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.

Beware the falling fruit. Scholars design and build parachutes that can help protect fruit as it falls. They test out their creations, learning about gravity, weight, air resistance, and measurement concepts along the way.

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. 

A one-stop resource for exponents, square and cube roots, scientific notation, and volume formulas guides learners through properties of exponents. As they learn to apply these properties to operations with scientific notation,...

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

Who said teaching a STEM lesson had to be challenging? Incorporate a career and technology-centered car build into your upcoming force lesson plan, and your class will be moving down the road in no time! Pupils practice...

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...

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...

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

Raise awareness of eating disorders with a two-activity lesson with middle schoolers reading articles to gather background information and then create audio messages and advertisements that promote healthy self-esteem and body image.

Scatter plots are a fun way to gather and collect relevant data. The presentation goes through several examples and then describes the different types of correlation. 

What is obesity and what are some steps that can help? Investigate obesity by having your class read and discuss articles about obesity. Students gain knowledge about body mass index, the food pyramid, being overweight and dieting. They...

Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...
