It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

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...

Convey to your pupils the importance of units, then show how to use dimensional analysis to perform a unit conversion. The math lesson includes detailed worked-out solutions to guide learners in their practice.

Does the number of calories you eat affect the total time you sleep? Young mathematicians tackle this question by collecting their own data and making comparisons between others in the class through building scatter plots and regression...

Certain things just do not mix, including liquids of varying densities. Learners collect data to determine the densities of several liquids. They then use the density information to predict the type of liquid.

Compose and decompose sets of 13 and 14 and compare sets of each with your little learners. They use objects to construct sets of 13 and 14, record their answers, and compare sets in several different ways.

The introduction to the lesson mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and map activity to...

Young scholarsare introduced to the Pythagorean Theorem by exploring right triangles and the squares built on each side. They apply the Pythagorean Theorem to real-world problems. Students u se informal and nonformal arguments of proof...

Students discover the relationships of the lengths of the sides of right triangles and right triangles using a series of drawings on dot paper. They investigate and solve problems of standard (customary and metric units) and non-standard...

Upper graders use the properties of right angle trignonmetry to measure objects such as the school flagpole. They solve real world problems using these properties.

Students discuss plate tectonics and the layers of the earth's interior. They use eggs as models of the earth and answer questions regarding which part of the egg would represent which part of the earth.

Using food as a manipulative is one of the best ways to incorporate hands-on learning in the classroom. This hands-on approach allows young mathematicians to compare, order, and identify fractions with the use of Twizzlers® and...

Students practice saying their numbers and identifying the words. They use whole numbers and decimals to practice grouping numbers into different categories. They write the word of the number they are shown.

Count and compare numbers and fractions using "greater than" and "less than." Learners count on by 2s and 10s and represent the end number with base ten blocks, counters, and cups. They use circle stickers to illustrate fractions and...

Seventh graders explore estimation, measurement, and probability. Students conduct surveys and create charts & graphs. They study the history of chocolate. Students design their own magazine advertisement or create a script for a...

Pupils use blocks and markers to illustrate the processes of adding, subtracting, multiplying and dividing integers. In this mathematics lesson plan, learners use Algebra blocks to demonstrate multiplying polynomials.

In this similarity worksheet, students determine the length, area and volume of similar figures. This three-page worksheet contains explanations, examples, and 20 problems. Answers are provided on page three.

Learners identify triangles as similar or congruent. In this geometry lesson, students drag triangles around on the navigator to see the effect of different angles on the shape of the triangle. They discuss angle similarity and angle...

Sixth graders use newspapers to investigate fractions. They work in small groups to categorize articles, measure them with the grid transparency, and calculate the values represented. Afterward, they write a reflective essay on the role...

Eighth graders discover the relationship between speed, distance, and time. They calculate speed and represent their data graphically. They, in groups, design a ramp for their matchbox car. The goal is to see who's ramp produces the...

Students determine crude oil can be separated into useful fractions by a process of fractional distillation. They write a balanced equation for the reaction between a hydrocarbon and oxygen.

Learners construct three-dimensional models of the three pyramids at Giza. They research the building of the pyramids and record the height, base and angle measurements of each pyramid. They create a file of facts regarding the pyramids.

In this Algebra I/Algebra II worksheet, students solve problems involving direct variation.  The two page worksheet contains a combination of twelve multiple choice and free response questions.  Answers are included. 

Students compare prices and determine percent increases and decreases of items in order to make wise purchases. In this percent increases and decreases lesson plan, students calculate the amounts based on grocery store ads.
