Stress the importance of the different types of pressure our mind and body experience in a lesson about how certain types of stress are actually necessary and good for our bodies. As astronauts and people with injuries can attest, not...

How likely is it that the school cafeteria will serve chicken tomorrow? Discover the concept of probability with the roll of the dice. Pupils evaluate the liklihood of several statments about everyday life. Then, a mathematical...

Three, two, one, blast off to a better understanding of force and motion with this exciting science lesson! Beginning with a discussion about rockets and gravity, young scientists go on to complete a series of worksheets about net...

A comprehensive resource gets fourth grade physical scientists making observations about the period of a pendulum and then applying knowledge to a playground swing. Through seven different stations, they will record observations and...

Ready for a lab with a lot of razzle-dazzle? Young chemists observe flame tests of common salts through an always-popular activity. The updated resource focuses on observation skills, collaboration, and green chemistry practices.

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

Blow your learners' minds with a sweet lesson on nanotechnology that uses sugar to demonstrate the difference nanoscale surface area makes in dissolving and crystal formation. Plenty of supportive background information is read to...

To prepare for the activity, STEM classes read about nanotechnology and the amazing properties of graphene. They collect a graphene sample from pencils, and then connect them into simple circuits to determine whether it makes a better...

Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

Energy conservers investigate gravel size to discover if it impacts the amount of oil recovered in the extraction process. 

By rolling marbles down a six-foot length of track, physical scientists determine how much energy is lost to heat. It is recommended that you opt for the foam pipe insulation track because more friction slows the marble, allowing...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

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...

Using a simulated air sample, environmental or earth science pupils examine the components. You will need to prepare the faux air by using a hole punch and various colors of construction paper. Each color will represent a different...

How does gravity affect the life cycle of a butterfly? Learn first-hand what types of investigations astronauts perform in space by following along with one of NASA's experiments. Create butterfly habitats in the classroom with specific...

This lesson certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many motion concepts:...

What adaptations exist in order for icefish to survive the subfreezing temperatures of the Antarctic Ocean? Middle and high schoolers can find out through watching a related 13-minute video and performing a simple investigation to...

Does a spider spin its web differently in space? What other ways might microgravity affect an arachnid? Pick a topic to research, plan an investigation, and follow astronauts on the International Space Station as they perform some of the...

Introduce emerging engineers to the process of metal plating. This resource provides background reading on chemical engineering, plating, and corrosion. It concludes with a copper plating activity. The standards alignment list includes...

A well-developed lab sheet guides physical science learners through an investigation of kinetic and potential energy. In small groups, collaborators discover whether or not the ramp height or mass of an object has an effect on the...

Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....

How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available....

Systematically diluting a full-strength sample of food coloring is meant to help earth scientists understand concentration in parts per million. While they will enjoy the lab exercise, it might be a challenge to help them relate it to...
