Learners perform an experiment to measure the density of tap water vs. salt water.

Show high schoolers there is more to quadratic functions than just formulas and parabolas. Connect the math to realistic application problems with a resource that has learners consider such situations as a ball hit in the air, the...

Sixth graders investigate the relative diameters of planets and distances between them and the cause for seasons on Earth using the 5-E Learning Model. They appreciate the size and distances involved with objects in the real universe....

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...

A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and...

Learners explore volume in relation to centimeter cubes and other nonstandard units of measurement using small containers. They will use hands-on materials to practice this concept. You will need small objects and containers to set this up.

Cell size is limited by the surface area to volume ratio, but why is this true? Scholars measure the surface area and volume of cubes before placing them into liquid. After a set amount of time, they measure the uptake by diffusion for...

Combine geometry and algebra concepts to solve a modeling problem. Young scholars consider the effect surface area has on volume. They write a cubic function to model the possible volume given a specific surface area and then...

Investigate bubbles through the use of scientific inquiry. Pupils blow bubbles using several methods and measure the resulting bubble print. Measurements are recorded on a data table and transferred to a bar graph. Results are discussed...

High schoolers determine the surface area of the Luxor Hotel, using the square feet of the base, volume, and the volume formula. They create a scale model of the triangular/pyramid shaped hotel.

At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...

Plant respiration can be a difficult concept for young biologists to grasp; with a hands-on lab, learners can collect and graph data, then calculate the metabolism rate for the plants they studied. If you do not have a respirometer,...

Find the math in recipes. Young chefs will follow a recipe and investigate the total cost for materials. They measure amounts of food necessary for the recipe and compute the per person cost.

Examine the concept of stoichiometry using common household products. Scholars perform chemical reactions and measure the reactants and products. They compare their measurements to predictions made from the chemical equations.

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

You don't want to be short bananas when making bread. Scholars use their math skills to make sure there are enough bananas to go around. Using measurements given in a recipe, they must determine how many bananas they need to increase the...

Sixth graders design rectangular gardens with a given perimeter and generalize how to maximize the area Students applying the formulas for perimeter and area of polygons. They analyze length, area, and volume and make relationships...

Algebra and geometry are not interchangeable. Demonstrate why not with a series of problems that deal with the equations of circles and equations of lines that meet specific criteria. 

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...

Learners comrehend that water displacement is a simple way to measure the volume of a solid object. They pour water into a graduated cylinder or measuring cup and its volume is read and recorded. Pupils the volume of an object by...

Students investigate ways to find the density of irregular shaped objects. In this physics lesson, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Students explore the relationship between mass, volume and density. They use model boats to discover how changing mass and volume affect density. This is a very engaging lesson plan which provides great demonstrations and hands-on...
