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....

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 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...

Students use formulas to design and create a table.  In this calculations lesson students create basal measuring tapes that will be used to measure woodlot stocking levels. 

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 examine how the circumference, diameter, and the relationship of Pi of a circle are related. They count the summer rings of a tree to determine its growth.

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

Electrical current going round and round,produces a magnetic field. After a demonstration of the magnetic field surrounding an electrical wire, class members use the provided formula associated with Biot-Savart's Law to calculate the...

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...

Students investigate how to make a good parachute. In this physics lesson, students observe the motion of parachutes as it falls and measure the time. They collect data and calculate the average descent time for each canopy shape.

Simulate a random sampling of data by tearing 20 sheets of paper into slips and place a number on 10 and a letter on 10. They place the slips in two separate containers and randomly draw a number and a letter. They record their...

In this random sampling worksheet, students compare data collected by a random sample to data collected by an actual count using pieces of paper with numbers written on them. They compare their data for the actual count to the random...

In this astronomy optics worksheet, students calculate the angular resolution and maximum resolution for given telescope specifics. This worksheet has 3 problems to solve.

Third graders discuss light sources and collect data about energy sources. They compare data and create a multiple line graph showing energy used by light sources for each student in the group. They present their graphs and write a...

Learners work together to complete an experiment calculating the amount of board footage in a tree. They record their data and answer questions at the end of the lesson plan. They create their own hypothesis as well.

Ninth graders explain how wind can produce electricity. In this geometry lesson, 9th graders construct their own pin wheel turbine and calculate its power. They discuss the pros and cons of using wind generator.
