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.

Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-lesson worksheet to help focus pupils on the task at hand. 

Learners investigate time. In this investigative lesson, students run through an obstacle course using standard timers. They record the time and apply this knowledge to problems in math. Learners record their predictions, and graph...

Students place events in sequence and assign relative times to each event. They gain an understanding of relative and numerical time and become familiar with the methods used by scientists to develop the Geologic Time Scale.

Rivers aren't just a place for animals to live, they also provide industrial transportation. The class will examine the Hudson River on a map, discuss all the commercial vessels that use the River to transport materials, then complete a...

Fifth graders convert units within the same measurement system and be able to determine elapsed time. They are given a start time and an end time of a game. Students determine the amount of elapsed time from the data that is given.

Students explore the evolution of time measurement, and explain the relationship of sunrise/sunset to length of daylight. They collect data and calculations to determine length of daylight during a given day.

Students make a sundial. In this time lesson, students determine the time of the day by creating a sundial. They check the time on the sundial, hourly, for one week. Afterward, they explore what happened to the shadows in reference to...

Using a plastic dome  to represent the hemisphere of the sky, your class is able to demonstrate the path of the sun at different points of the day and year.  They use a protractor to record movement and answer questions about...

In this time intervals instructional activity, students solve 8 problems where they determine the time gamma-ray bursts last, the time black hole micro-flares are emitted, the time coronal mass ejections travel and the days between lunar...

Students discover that volcanic eruptions are geologic events that take place within the upper part and on the surface of the Earth's lithosphere. They explain how volcanoes are related to the Earth's lithosphere. They focus on the May...

Third graders read the article "Blue Claw," discuss crab migration, and look at a map of the Hudson River. They complete a worksheet where they must use subtraction to determine the distance migrating crabs travel.Web links, article, and...

Students explore the concept of time. Through discussion and artistic projects, they define time in their own words and tell how it is used to represent the seasons. Students draw a picture to portray time as it elapses during the...

Students explore speed by calculating the average speed of several snowmobiles, and predicting which of them is the fastest. They watch a race to verify their calculations.

Fourth graders become familiar with a chart and use the information to create a flight plan.  In this flight plan lesson plan, 4th graders access background knowledge of the role of flight controllers and the number concepts they...

Sixth graders investigate the importance of observing safety rules in the use of electricity. They discuss electricity safety rules, observe a power company employee read a meter, write and perform a commercial about electrical safety,...

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

In this variables and expressions worksheet, students solve 7 problems using different mathematical formulae to find the length of Earth's day in the future, the distance to the galaxy Andromeda, the temperature of a gas cloud emitting...

In this orbital period worksheet, students solve 2 problems about satellites and their orbits. They determine how many days it takes for two satellites to be in "opposition", they find the least common factor between their orbit periods...

Using data related to the fish in the Hudson River area, learners calculate distance, elapsed time, and growth. They learn about migratory fish, the life cycle of a fish, analyze a map, and answer questions.

Students construct clocks and then learn how to read a clock face, tell time, and determine how much time has elapsed.

Your Algebra learners analyze and solve an exponential equation in this popular, real-life model of the cooling of a liquid.  

High schoolers use a migration map to estimate the distance traveled by a bird while migrating south. After calculating accurate estimates of the distance traveled, students compare the distances traveled with the amount of time elapsed.
