Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

In this coronal mass ejection learning exercise, high schoolers read about the coronal mass ejections detected by the IMAGE satellite and the Hubble Space Telescope resulting in auroras. Students solve 6 problems and determine the speed...

Students examine the suggestion that the subjective experience of everyday life and sense of identity has changed in America in recent years. In this post-modernism and mass culture lesson, students engage in 4 multi-step exercises that...

In this weapons of mass destruction worksheet, students read the article, answer true and false questions, complete synonym matching, complete phrase matching, complete a gap fill, answer short answer questions, answer discussion...

For this sun worksheet, students read about calculating the internal density and mass of the sun. Kids use a given formula for the internal density of the sun's gases which students use to solve four mathematical problems.

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Explore the mathematical relationship between a solvent and solute. Learners use technology to measure the cooling patterns of a solvent with varying concentrations of solute. Through an analysis of the data, pupils realize that the...

Engineer an autonomous underwater vehicle (AUV) to study concepts of physics. Using household materials, collaborative groups design and build an AUV and then test Newton's Laws of Motion as they apply them in underwater environments...

How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....

Almost complete annihilation of the plants and animals on the Earth has occurred at least five times in the past. Young scientists explore each of these events. They learn about the evidence and conclusions for each event and connect...

Are you feeling weighed down by your current gravitation presentation? Assign a hands-on interactive instead! Physics scholars work through a series of progressively harder questions about mass, distance, and gravity using an online...

Budding scientists fall hard for a gravitational field strength activity! Physics pupils compare the masses and distances relative to the center of planets using an interactive from a Circular and Satellite Motion series. Individuals...

Ready, aim ... learn! Increase scholars' understanding of force, mass, distance, and angle using an engaging interactive. Pupils participate in a series of rescue missions where they launch supplies at a target with an adjustable cannon....

A mass extinction event caused by an impact usually leaves a crater. Scholars use data from 10 different sites around the world trying to determine where to look for the crater. They use data, listing the amount of various minerals to...

In this moles worksheet students complete a set of calculations to find how many atoms and moles are in different substances. 

Francis Raoult discovered the change in boiling points of solutions varies by the number of particles in the solution. Scholars apply the concept to determine the molality of a solution based on the change in boiling point. They use an...

What can fossils tell us about periods of extinction? Young scholars interpret fossil layers to make conclusions about changes in life during different geological time periods. They analyze the fossils for abundance and diversity as well...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...

Three memorable activities build on each other to give physics masters a firm grasp of Newton's Second Law. Pupils play with a lab cart on a flat surface and on an incline to confirm that force is equal to mass times acceleration. In the...

In this chemistry Olympiad lab worksheet, students are given two lab problems to design experiments. Topics include determining the mass percentage of a given compound and determining an unknown metal using quantitative and qualitative...

In this chemistry olympiad laboratory activity, learners design and carry out two experiments. They design one experiment to test for the percent mass of a substance in a solution and they design another experiment to identify two...

Through a series of worksheets, mathematicians practice with various concepts of measurement. Conveniently, the 6 pages are easily broken up for individual assignments, and seem to progress in difficulty. Math concepts include drawing...
