Energy & Work

Energize your physics lecture on energy and work with the various resources that Flinn Scientific has collected.

Large Scale Demonstrations for Physical Science

Mesmerize your students and inspire with spectacular large scale physical science demonstrations!

Mousetrap Cars—Super Value Guided-Inquiry Kit, AP7667

Mousetrap Cars - Super Value Guided-Inquiry Kit shows how students become real world engineers as they investigate the various parts of a car powered by a mousetrap.

Collider, AP6473

Collider shows how you can teach conservation of momentum and two-dimensional collisions with this unique ball-launching ramp.

Investigating Impact Craters—Super Value Kit, AP7676

Investigating Impact Craters Student Laboratory Kit will help your students understand why some craters are bigger or deeper than others.

The Bungee-Jumping Egg—Super Value Laboratory Kit, AP6381

The Bungee-Jumping Egg Super Value Laboratory Kit shows how students are challenged to design the most exhilarating and safe bungee jump using scientific and engineering practices.

Tornado Tube, AP1930

Tornado Tube explains how you can create a mini-tornado in your classroom by employing hydraulic principles to create the vortex of a tornado.

Magnetic Linear Accelerator

Magnetic Linear Accelerator can be used to demonstrate potential versus kinetic energy, conservation of energy, and magnetic potential energy.

Gyroscope Bicycle Wheel, AP4610

How To Use the Gyroscope Bicycle Wheel demonstrates the conservation of angular momentum and rotational kinetic energy.

Binder Clip Catapults

Binder Clip Catapults demonstrates how to inspire an atmosphere of engineering in your classroom with this fun, high flying activity that uses simple, low-cost materials in this Flinn Physical Science Minute.

Mechanical Advantage of Pulleys

Mechanical Advantage of Pulleys is a Flinn Physical Science Minute that shows a simple way to help your students understand the concept of mechanical advantage of pulleys.

Bowling Ball Swing

Bowling Ball Swing demonstrates the law of conservation of energy.

Energy Toys

Energy Toys uses an assortment of toys to illustrate the concept of conservation of energy.

An Easy Hero's Engine

An Easy Hero's Engine demonstrates how an engine works by converting heat energy into mechanical energy.

Putt-Putt Steam Boat

Putt-Putt Steam Boat shows how an old-fashioned toy steamboat runs on steam by converting chemical and heat energy into mechanical energy.

Kinetic Energy Demonstration

Kinetic Energy Demonstration uses small pieces of metal shot as models for the kinetic-molecular theory of matter and the properties of gases.

Bowling Ball Swing

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.

An Easy Hero’s Engine

Phase changes are taught at just about every level of science education, K–college. Rarely, however, is it emphasized what an important role they have played historically in our technological development. The boiling of water, after all, was what first allowed us to take significant advantage of chemical energy, enabling us to convert the heat given off during an exothermic reaction into useful work. How wonderful then that one of the earliest and most fundamental steam engines can be replicated with an aluminum soda can!

Putt-Putt Steam Boat

Light a small candle inside a toy boat and watch it coast around the water while making a “putt putt” noise. Use this old-fashioned toy to illustrate how chemical energy is converted into mechanical energy as phase changes occur.

Kinetic Energy Demonstration

Small pieces of metal shot and BBs are good models for the kinetic-molecular theory of matter and the properties of gases.

Celt

A hard-boiled egg will spin both counter-clockwise and clockwise. Do you believe this is true of all shapes of stones?

Build a Binder Clip Catapult

Catapults have been used to launch projectiles during battles from the time of the ancient Greeks to World War I. Make a catapult using simple materials and then test the machine to see what variables affect launch distance. Improvements may then be made to increase the accuracy of the launch.

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.

Rolling Race

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!

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.

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.

Bungee-Jumping Egg

Bungee jumping would not be as “safe” as it appears to be without relying on some basic physics principles, such as the conservation of energy and Hooke’s law for springs. A safe bungee jump occurs when no one is injured. An exhilarating bungee jump is one in which no one is injured, the free fall lasts as long a time as possible, and the bungee jumper comes as close to the ground as possible without touching it. In this activity, the law of conservation of energy and Hooke’s law will be used to build a safe and exhilarating model bungee jump of an egg!

Celt Spoon

When an oblong, boat-shaped object—known as a celt, rattleback or wobblestone—is rotated about its vertical axis in a particular direction, it will stop rotating, begin oscillating, and then spin in the opposite direction. Here’s how to construct your own mysterious celt from an ordinary spoon.

Simple Block and Tackle Pulley Demonstration

How much easier is it to lift a heavy object using a pulley system? Use this simple broomstick-pulley system to effectively demonstrate why a block and tackle pulley system is so useful.
