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...

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...

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...

Your class will use a set scale to convert diameters of planets to the model size, the diagram given to expand on the number of planets drawn as concentric circles, and examine the scale that would be needed to fit the larger...

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...

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.

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.

In this area and probability worksheet, students solve 5 problems where they find the probability of an event occurring. They also use a given photograph of the moon's surface to find the area covered by craters and determine the...

Class members create their own social networks by collecting signatures before graphing the interactions with their fellow classmates. The degree distribution of the simulated social network is determined by calculating the degree of...

In this Hubble Space Telescope worksheet, students are given a photograph of the radiator recovered after being in space on the Hubble Space Telescope since 1993. Students solve 6 problems about the impacts that left craters on the...

For 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...

In this Sun and Moon worksheet, students solve 6 problems about the angular scale of the images given, the size of the features on the images and the area of the features shown.

In this hunt for planets worksheet, students read about the Kepler satellite used to detect exoplanets. Students solve 6 problems including drawing a sun disk and determining the scale in kilometers/millimeter, finding the area of the...

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.

Students 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.

Ninth graders research the average temperature and precipitation of a prairie region to determine the type of climate it is, and how it differs from other biomes. They examine the types of adaptions animals have made to live in the...

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...

Students examine the characteristics of living things. They list the differences between living and non-living things, explore areas around the school, and create a Venn diagram for items found in the school areas.

How do you grow crops in a area with insufficient rainfall? Why you irrigate, of course. Class members investigate irrigation systems by designing a system of their own. After examining irrigation related concepts, vocabulary terms, and...

For this wheels and axles worksheet, students read a 1 page article, make a list of how many objects they can find or think if that uses a wheel or axle and then design their own machine.

Students identify the different types of bridges. Using the internet, they research information on how they are built by completing a scavenger hunt. Locating a specific area, they determine which type of bridge would be appropriate and...

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...

Students examine and study how changes in perspective can change the way that they can observe objects. They explore the relationship between a scene's area and its detail. Each student looks at the ground through cardboard tubes from...

Learners study what makes Earth warm and explore how different locations on the planetreceive different amounts of solar energy based on the intensity of the sun's rays. They calculate light intensities and compare the amounts of light...
