Students examine gravity, mass, and friction. In this speed and motion instructional activity, students investigate how straight line motion is impacted by gravity, mass, and fiction as they participate in a hands-on activity.

Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...

How do you convert inches to centimeters? Or pints to liters? This handy reference guide has both US to metric, and metric to US conversions in a quick, easy-to-read format. Mass, area, volume, capacity, and length conversions are...

Preparing for an AP test is about more than bubble sheets and memorization. The two activities in this resource require a direct application of skills learned throughout an AP Physics course.

Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...

Prove the Law of Conservation of Mass through a lab investigation. A well-designed lesson asks groups to combine materials and monitor indicators for chemical reactions. Measuring the mass of the reactants and products allows individuals...

Students examine containers and their capacity. They fill a one-cup measuring cup with water and pour cups of water into other containers. Through observation, students discover how many cups make a pint, and how many teaspoons make a...

Beware the falling fruit. Scholars design and build parachutes that can help protect fruit as it falls. They test out their creations, learning about gravity, weight, air resistance, and measurement concepts along the way.

Students study the concepts of weight and drag while making paper helicopters. They measure how adding more weight to the helicopter changes the time for the helicopter to fall to the ground. They apply what they examine to the work of...

This is the grown-up version of the classic "float an egg in salt water" experience, plus an experiment in soap making. High schoolers explore density, but more importantly, practice accuracy, precision, and the use of significant...

After taking in background information on teeth, marble, eggshell, and fluoride, chemistry aces design an experiment. Their goal is to demonstrate whether or not fluoride has a similar effect on marble or eggshell as it does on tooth...

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...

Students discover the metric system through video clips and Internet activities. In this measurements lesson, students practice using the units of measure for the metric system and compare them to the less popular English system....

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

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....

Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson in a seven-part series challenges scholars to find the mass and volume of two unknown liquids. Each...

Accomplished chemistry learners set up a calorimeter and measured the energy released by various alcohols: methanol, ethanol, and either propanol or butanol. Lab masters will first need to design their tables for recording data. Consider...

Teacher's notes, a materials list, detailed procedure, tips, and extension ideas are all included to make teaching this lesson on photovoltaic cells a sunny spot in your day! After some brief background reading, physical science...

Whether in the UK or the US, the mass of the copper in a copper alloy penny can be determined. If you are in the US, note that on the lab sheet, a penny is identified as a "1p piece." The penny is dissolved by young chemists in nitric...

The humble soda can gets the geometric treatment in an activity that links math and science calculations. After a few basic assumptions are made and discussed, surface area calculations combine with density information to develop an...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Don't waste all that carbon dioxide. Scholars first produce carbon dioxide by mixing baking soda and vinegar. They measure the masses of the reactants and products to verify the law of conservation of mass. As a culminating activity,...

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Bathymetry is not a measure of the depths of bathtubs! Through the three lessons, scholars explore two different types of maps and how they are made. The resource focuses on topographic and bathymetric maps and teaching the techniques...
