Students explore different size circles to discover the relationship between diameter and circumference. In this circles and Pi lesson, students construct simple parachutes using circle patterns of varying sizes. Students predict the...

Mathematicians analyze the relationships between surface area and volume. They conduct Internet research, conduct various experiments, record the data in a spreadsheet, and graph the results and compare the rate of increase of surface...

Students examine the relationship between circumference and diameter and how to use the formula to find the area of a circle.  In this circle lesson plan students divide into groups and complete an activity. 

There's no way around it—learners must use trigonometry to model the line of sight around a race track! Using the starting line as the origin, pupils model the straight line distance to any car using a trigonometric expression. The...

In this Saturn's rings worksheet, students read about the Spitzer telescope that detected a new ring around Saturn. Students solve 6 problems including determining the formula for the area of a circle, finding the volume of the new ring...

Round and round in circles it goes! A hands-on activity has learners recreate a model of a convection cell. They watch as the difference in density of their materials creates a current.

High schoolers use graphs and plots to measure the basal area and stocking levels.  In this graphing instructional activity students work in the field the use their data to help them complete a lab activity. 

Groups simulate an orbit using a piece of string and a water balloon. Individuals spin in a circular path and calculate the balloon's velocity when the clothes pin can no longer hold onto the balloon.

Pupils estimate the size of a molecule of oleic acid. They conduct an experiment using chalk dust, water, and oleic acid, solve various calculations, and answer discussion questions.

Go around and around in your physics class with this presentation on circular motion. Diagrams bring the definition to life. Formulas for angular acceleration, centripetal force, gravitation, and potential in a radial field are given....

The molecular properties of water are the focus of this chemistry-based assignment. Multiple-choice, true-or-false, matching, and fill-in-the-chart style questions query assignees about the forces that hold the water molecule together,...

Students investigate the best way to calculate the measurements of an area. In this geometry lesson, students relate a large circle to a cylinder and its measurements. They use PVC pipes to gain hands on experience as they calculate the...

High schoolers solve five problems including finding the cross sectional area of two bodies, determining the swept out volume of a moving body, finding the average particle volume of a body and determining the collision time for a body.

Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...

Focused little scientists will flitter their arms back and forth across the room with excitement as they learn the life cycle of a butterfly and how living things grow and change over time.

First year physics learners show what they know about electric potential, circuits, power, current, and voltage on this midterm exam. It consists of a multiple choice section, some true or false questions, and two multi-step problems to...

Students investigate the circulatory system. In this circulatory system lesson, students complete a WebQuest and explore all the areas of the heart. Students determine the functions of different parts of the circulatory system and...

Learn about polar bears and the Arctic circle with a lesson about the countries and conditions of the region. After examining how the area differs from Antarctica, kids explore climates, animals, and geographical position...

Observe the differences between the inside and outside of a pumpkin. Learners discuss what pumpkins are used for and then view a pumpkin. Next, they view the inside of the pumpkin and draw the differences they see.

Clever! In order to compare indoor and outdoor dispersal rates for the movement of gases and particles through air, collaborators will participate in a classroom experiment. Set up a circular grid and set students on lines that are...

Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

How much plastic do manufacturers use to create water bottles each year? The class explores the number of water bottles used throughout the years to determine how many consumers will use in the future. Class members compare different...
