Soda Can Calorimeter

Have you ever noticed the nutrition label located on the packaging of the food you buy? One of the first things listed on the label are the calories per serving. How is the calorie content of food determined? This activity will introduce the concept of calorimetry and investigate the caloric content of snack foods.

Alternate Text

Build the Simplest Electric Motor

Challenge your students to build a simple motor with only three components: a battery, a piece of copper wire and a strong magnet.

Alternate Text

Land Versus Water

While at the beach on a hot summer day, have you ever observed the temperature difference between the dry sand and the body of water? You nearly burn the bottom of your feet trying to get to the water! Why is there such a huge temperature difference between land and water? Use this activity to get your students thinking about the concept of specific heat and why various substances have different specific heat values.

Demonstrating Waves

Waves are all around us! You may not be aware of it, but we encounter waves on a daily basis. Use these demonstrations to help your students visualize the properties of waves and wave propagation.

Alternate Text

Bowling Ball Pendulum

Students may think it is foolish to place their face in front of a heavy, swinging bowling ball. However, this classic demonstration will clearly illustrate the conservation of energy principle.

Alternate Text

Rubber Band Cannon

What determines how far a cannonball will fly? How does the launch angle of a cannon affect its range? Explore some of the variables that influence projectile motion using a Rubber Band Cannon.

Alternate Text

Heisenberg Uncertainty Principle Simulation

Use diffraction to explain and demonstrate the Heisenberg Uncertainty Principle.

Alternate Text

Introducing WhiteBox Learning

Engage in real-world, turn-key applied STEM with the WhiteBox Learning process of informed iteration!

Alternate Text

Flame-Retardant Balloon

Show students a “special” balloon that doesn’t pop when exposed to a flame. Students will come up with very clever ideas for why the balloon doesn’t pop. But, when all is said and done, the “magic” is the result of important scientific principles involving specific heat capacity and heat transfer.

Alternate Text

Magnetic Linear Accelerator

Create a simple magnetic linear accelerator using magnets and steel ball bearings! Demonstrate magnetism, the conservation of energy and momentum and projectile motion.

Alternate Text

Gummy Bear Wave Machine

Amplify your students’ understanding of wave motion with this captivating demonstration! Using simple materials, students can have significant influence on large-scale variables of frequency, amplitude and wave speed as they observe wave motion through a medium.

Alternate Text

Centripetal Acceleration

Take your students on an amusement park ride—for just a penny! Discuss how an object can be accelerating yet moving at constant speed. Investigate how a change in direction (at constant speed) is acceleration; that is, centripetal acceleration!

Alternate Text

Bouncing with Momentum

The collision of objects is a great way to demonstrate the conservation of momentum. Engage students by having them drop and collide toy balls of different mass and size. The results may be surprising! This inquiry-based activity will really get your students thinking about momentum.

Alternate Text

Students experience the effects of inertia every day—riding in a car, playing sports, even when picking up their backpacks. Present a more dramatic demonstration of Newton’s first law by safely dropping three raw eggs into glasses of water, without touching the eggs! Applause is guaranteed!

Alternate Text

It’s a race! Investigate the properties of the moment of inertia by rolling differently shaped objects, such as a solid disc, ring, and sphere, down an incline. Discover why the sphere always wins!

Sample Activity for Flinn STEM Design Challenge Book (Catalog No. AP8333)

Alternate Text

Water Drops on a Penny

Why do water droplets bead when dropped on a waxy surface? Why can some insects walk on water? These observations can be attributed to the high surface tension of water. Surface tension is the result of attractive forces between molecules. Water’s large contribution to life on Earth depends on its unique properties. Without it, life on Earth would be impossible.

Alternate Text

Aluminum Air Battery

Build a dry cell battery with this fun activity! Batteries provide electricity for nearly every small electrical device in the home—from flashlights to power tools. The composition of a battery depends on the purpose for which it will be used. Some batteries, such as those in an artificial pacemaker, need to operate for a very long time. Other batteries need to be reliable and ready to supply electricity at any time, even after several years of storage.

Alternate Text

Resonance with Washers

Have you ever heard a crystal glass hum when someone runs a finger around its rim? Do you remember the great height you could reach on a swing when you pumped your legs with proper timing? Do any objects in your home vibrate when music is playing? Although these observations seem to be unrelated, they all involve a phenomenon known as resonance.

Alternate Text

Solar Oven STEM Challenge Activity

Capture solar energy in a useable way! Learn how solar ovens work and cook some yummy snacks with energy from the sun with this Flinn STEM Design Challenge.

Alternate Text

Color and Light Spectrum Demonstrations

Is there more to light than meets the eye? Does a green filter change white light into green light? What color of light is observed when blue and yellow filters are mixed? This demonstration uses a holographic diffraction grating and an overhead projector to produce a large, sharp rainbow of color. The large spectrum allows you to demonstrate the true nature of color and light and address common misconceptions related to the perception of color.

Alternate Text

Smartphone Spectroscopy

A spectroscope is a device for forming and observing the color spectrum of visible light. A spectrum is produced when light from any source is bent or dispersed. Does every type of light show the same spectrum? Turn your smartphone camera into a spectroscope to find out!

Alternate Text

Balloon Rocket Blastoff

Have you ever watched a rocket or space shuttle soaring through the sky? How is it possible for these massive objects to move through the air? The basic principle behind rocket flight is Newton’s third law of motion. In this activity, students will experiment with Newton’s third law by launching balloon rockets across the classroom.

Alternate Text

Twirling Toy Challenge

In the Spring, maple trees release multitudes of seeds into the air. They carelessly spin and drift in the wind until landing at their final destination, the ground. What causes the flight patterns the seeds follow? A twirling toy demonstrates the same careless flight and by manipulating different factors of the twirling toy, you can discover which factors are more influential.

STEM Integration Guide for Flinn Up, Up and Away Hot Air Balloon Kit

After witnessing the ascent of a manned hot air balloon in Paris in 1783, Benjamin Franklin described the event as “a most beautiful spectacle.” Watching these airships glide across the sky still evokes a sense of awe and inspiration today. Generate the same excitement in the science classroom with model hot air balloons!
