Make sure to consult the teacher's handbook, Inquiry in Action - Investigating Matter Through Inquiry, for two demonstrations that can be done to introduce solubility and measuring crystal mass before having the class conduct this...

Combines mathematical measurement with gardening skills. Third graders hunt for worms in the garden and try to find the longest one. They also measure and weigh vegetables that they harvest from the garden, measure rainfall amounts,...

Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....

To wrap up your year of general chemistry, have lab groups compete in a tot wire chemical vapor deposition (HWCVD) competition. With their foundation in chemical nomenclature, stoichiometry, and gas laws, each group completes several...

Push the envelope with this lesson on atmospheric pressure! Your physics or geology juniors will be amazed at your super-human ability as you demonstrate the breaking of a stick using a newspaper! They also work with peers to construct a...

The first activity may not work for your class if you don't have access to an open area of 30 meters and two cars of different masses, but the remaining activities can be used in any physics course. They all involve the investigation of...

Physical science scholars discover an array of heat sources. They experiment to connect radiation to heat. They begin to understand thermal equilibrium. Then, they test to see if mass affects the rate of temperature change. Choose a few,...

What happens when two worlds collide? In the first of several activities, future physicists experiment with colliding ball bearings or Newton's cradle. Another activity requires the use of an air track with cars to examine collision....

Physics learners experiment with three laboratory activities to learn about air resistance and friction. First, they use a hair dryer to move different sized spheres to determine the relationship between cross-sectional area and air...

In this science worksheet, students examine the graph with elements in order to differentiate atomic mass and categorizing the content.

Young scholars find the percent composition of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a sample of potassium chlorate to decompose it into potassium chloride and oxygen. They weight their...

Here is a tasty challenge, especially for middle school engineers: design a container that meets mass and volume criteria, and will safely transport a tortilla or potato chip through the mail without damaging it! Mostly, this is a crisp...

Canadian history is rich and full of social and industrial changes. Discover the Laurier Era which was marked by industrial growth, mass immigration, policy changes, globalized imperialism, and social reforms. Because this era spans from...

Is it possible to defy gravity? Not really. With force and inertia, we can act against it for a little while, but, eventually, gravitational force will pull us back to Earth. The relationships among mass, force, and inertia are all...

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

As physics masters view this presentation, they learn how nuclear power is used in submarines. They use Google Maps to plot a course through the ocean and calculate the time required for surfacing and traveling. They learn about fission,...

Three simple activities kick off a unit investigation of density. Your physical scientists make observations on the volume and mass of wood, water, and rocks, and make comparisons. Though this is written for grades three through eight,...

How is tug of war related to pushing a refrigerator? Here's a simulation connects these two activities with Newton's First Law of Motion. Four different simulations allow scholars to explore net force with tug of war, motion with pushing...

Orbit diagrams appear to be a work of mathematical art. The simulation helps scholars build their own systems of planets, stars, moons, etc., to observe their orbits. By altering their positions, velocities, and masses, a variety of...

Find the mass, volume, and density in five different equations with a straightforward worksheet. Each equation prompts kids to work through word problems of varying difficulty and to find the necessary measurement using different formulas.

You would think that humans make up more mass than ants do on this planet, but think again, and this time by performing calculations. Middle schoolers use scientific notation to compute and compare the estimated total mass of all humans...

Who knew F=MA could determine the force of a free-falling elevator? Give your class this set of thirteen word problems for practice determining force, mass, and acceleration of everyday objects. One question introduces an object in...

What happens to stars as they get older? A simulation takes pupils through the life cycle of stars based on their masses. The resource introduces the Hertzsprung-Russell diagram and the common relationships and life cycle patterns observed.

It is always a rush to drop objects from great heights, and with this physics experiment, class members will not be disappointed! They drop a single coffee filter from a balcony or table top, record the time it takes to reach the ground,...
