Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...

Celebrate the whimsical world of Dr. Seuss on Read Across America Day with a collection of science, technology, engineering, the arts, and mathematics activities, each linked to a popular Dr. Seuss story. 

Future engineers test different alloys to determine the specific strength of each one. Based on the results, they make a recommendation to NASA on which alloy to use on engines for spacecraft.

Careful, that light bulb is hot! Compare heat and light energy using a simple light bulb. The exercise addresses energy conservation and presents actual calculations to determine the most cost-effective light bulb.

Class members use a compass and several points to map out the magnetic field of a magnet. Pairs trace the magnetic field lines produced by a permanent magnet by positioning the compass in numerous spots around the magnet to view the...

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

Don't melt away! Pairs investigate different insulation materials to determine which one is better than the others. Using a low-temp heat plate, the teams insulate an ice cube from the heat source with a variety of substances. They...

Let the true colors shine through. Pupils conduct a flame test to identify an unknown element. Class members calculate and prepare specific molarity solutions of three chemicals. Using their observations of the colors emitted, they...

Water filtration — that's pure genius! Groups test the ability of a water filter to purify water by running chlorine contaminated water through a filter and measuring the chlorine concentrations as they filter the water. They then graph...

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

 The class must determine the magnetic properties of different materials, including aluminum and steel by sorting through materials using a magnet. Groups make a prediction on whether a material is magnetic and then perform...

Read all about it! Challenge your class to build taller and stronger. Newspapers provide the means to build towers in a simple activity. Scholars try to build as tall a tower as possible with just two sheets of newspaper.

How many humans does it take to power a light bulb? The 10th part of a 25-lesson Energy Systems and Solutions unit has learners conduct an experiment to calculate power. They then use the results to determine how many classmates they...

Slide books with a little assistance from Newton. Using books, groups create a demonstration of Newton's Second Law of motion. Pupils compare the distance traveled by one and two books when they apply a force to them.

This Discovery Education activity provides the information needed to understand the basics of flight. Before taking off, young pilots learn the eight stages of the engineering design process. Small groups then design and build...

Engineering challenges are not just man-made ... nature has its own set of them. A hands-on STEM activity has groups designing a seed dispersal system. Each group can only use one sheet of paper — a tough task!

Paper is made from paper, right? Future scientists take bits of paper and produce sheets of recycled paper. The only drawback? It has to dry overnight.

Don't kick the resource to the curb; you'll definitely regret it. Future engineers devise a kicking machine that launches a ping-pong ball toward a target. They can use a pendulum, a rubber band, or both, depending on whether they want...

Clamp onto the resource and don't let go. Future mechanical engineers produce a pipe clamp from a sheet of metal. This idea is to use the pipe clamp to affix a pull-up bar in a doorway.

Forget your local meteorologist — build your own barometer and keep track of the weather with an activity that provides directions to build a barometer out of a narrow necked bottle, a glass, and some water. Using their barometer,...

Knowing the temperature coefficient allows for the calculation of voltage output at any temperature. Groups conduct an experiment to determine the effects of temperature on the power output of a solar panel. The teams alter the...

Watch out below! Future engineers come up with methods to ensure that a ball in a cup stays in the cup even after dropped from a given height. It might be prudent to include some kind of shock absorber in the cup. Parachutes are a good...

What makes each one of us unique? Lead your class in this exciting and educational activity as you uncover traits that show how each individual is different from another. Pupils explore facts about DNA technology and predict the...
