Learners characterize a physical change as something that changes to a different size, but retains its basic substance. They measure volumes using milliliters, and perform an experiment that proves that gases expand when hot and contract...

Students explore mass, volume, and weight. In this science and measurement instructional activity, students compare volume, mass, and weight after listening to the teacher's description of each. Students explore different scales and...

In this cylinder worksheet, learners compare three different cylinders to experiment which one has the greatest volume. Students interact with rectangles as they experiment with the cylinders.

Third graders experiment with beakers of water and balloons to measure the volume of the gas in the balloon. They determine ways to change the volume of air in the balloon which changes its size but not its physical state. By heating the...

Students investigate the affect shape has on the ability of a solar panel to collect sunlight.  In this collecting sunlight using a solar panel lesson, students determine which solar panel shape collects the most sunlight. ...

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....

It's all about density! Here's a dense workbook for young scientists; they solve (and show work for) 29 density word problems, including a problem where they solve for the density of Godzilla. They complete labs analyzing metal...

Young scholars determine the amount of earth that needs to be removed from the Mississippi and the amount of time it takes the Army Corps of Engineers to complete a dredging project. Given specific dimensions of a channel, calculations...

Young astronomers follow a step-by-step procedure for dividing a lump of dough into parts, resulting in a scaled volume set of puny planets. Along with the printable directions is a template chart of planet names on which learners can...

Students enter a race against time to determine the maximum sized box that can be formed from a standard sheet of copy paper. The boxes are to be used to contain a valuable and rare element which is light as cotton and corrosive to all...

Students participate in an activity where they build a calibrated thermometer.  For this thermometer lesson students complete this activity and take notes. 

There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

In this physical science exploration, small groups place a piece of antacid tablet into a film canister and step back to time how long it takes for the top to pop. They repeat the activity, altering either the amount or temperature of...

Students analyze the amount of space required to pack round objects. In this geometry lesson, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to molecules being...

First off, Newton's laws of motion aren't often taught at 2nd grade, so this lesson may be more appropriate for upper elementary learners. It begins with a discussion and demonstration of the laws of motion, and then has individuals...
