Magnetic or Not?
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 tests to...

Design and Build a Rube Goldberg
Let's see how complicated we can make this simple task. The last activity associated with a 10-part series has groups design and build a Rube Goldberg machine. Teams determine a simple task to accomplish and use the engineering design...

The Magician's Catapult
Class members work in pairs to build a catapult to launch a grape a given distance. The catapult project, a compound machine, reinforces pupils' understanding of simple machines.
Teach Engineering
Machines and Tools (Part 2)
Which pulley system will give us a whale of a good time? Teams compare the theoretical and actual mechanical advantages of different pulley systems. They then form a recommendation for how to move a whale from an aquarium back to the ocean.
Teach Engineering
Tools and Equipment (Part 1)
Looking for the best inclined plane for the job? Groups calculate the theoretical mechanical advantage for four different inclined planes. They determine the actual mechanical advantage by measuring the amount of force needed for the...
Teach Engineering
Just Plane Simple
It is plane to see that simple machines help reduce the force needed to perform a task. This resource introduces three of the simple machines--the inclined plane, the wedge, and the screw, and the formulas in order to be able to...
Teach Engineering
A Simple Solution for the Circus
Class members are challenged to design a device that will move a circus elephant into a train car. Groups brainstorm ideas that use simple machines to load the elephant. They then choose one of their ideas, sketch a plan, and present it...
Teach Engineering
Egg-cellent Landing
The classic egg-drop experiment gets a new bounce with an activity that asks pairs to design a lander similar to one used to land a rover on Mars within a fixed budget. The activity provides a great introduction to the idea of terminal...
Center for Learning in Action
Density
Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.
Journey Through the Universe
Our Solar System
Take your class on a journey through our solar system. Learners explore each planet, from Mercury to Pluto, and discuss various features that differentiate one from another. They complete activities related to the topics and discuss the...

Manned Space Exploration: From Apollo to Present
How did the manned space mission program progress? The presentation covers American space exploration from the Apollo missions through the International Space Station.
Mr. E. Science
Atoms and Bonding
I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms in an equation,...
Mr. E. Science
Chemical Reactions
Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical equations...
Mr. E. Science
Forces in Fluids
Buoyancy is the fine line between a ship and a submarine. The presentation covers fluid pressure, air pressure, Pascal's Principle, elevation, Archimedes Principle, buoyancy, and Bernoulli's Principle.
Mr. E. Science
Motion
An informative presentation covers motion, metric system, conversions, graphing of coordinates and lines, speed, velocity, and acceleration problems, as well as mean calculations. This is the first lesson in a 26-part series.
Journey Through the Universe
Going through a Phase
Ignore the full moon, it's just a phase. Young scholars observe and record the moon during a full cycle before learning to predict future phases. Then the instructor leads a discussion on the other solar system objects that also go...
University of Saskatchewan
Using Conservation of Energy to Determine Average Impact Force
Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...
Genesis Energy
Harnessing Solar Energy
How does additional daylight hours affect people and nature? With the help from the legend Maui and the Sun and a grand conversation, scholars complete a graphic organizer to distinguish between the positive and negative effects that...

Taking a Closer Look at Objects
Take a close look at the world around you with an activity that magnifies everyday objects. Five explorations examine items under intense magnification and pose a series of questions that encourage critical thinking and following...
Mr. Science
The Scientific Method
First, ask a question and then, do research. Next, form a hypothesis, and conduct an experiment. Make observations, gather and analyze data, and then state a conclusion based on the results. This is the scientific method, and here is a...
Journey Through the Universe
Comets: Bringers of Life?
Young scientists investigate the elements found in our solar system and then construct a model of a comet. They apply their new knowledge to the formation of the solar system.
Journey Through the Universe
How Far is Far?
The earth only revolves around one thing — and it's not any of your pupils. The lesson includes two activities dealing with the distance to the sun and the moon. First, scholars create a pin hole camera and use the rules of similar...
