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.

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 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...

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.

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...

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...

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 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...

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.

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...

Students calculate elapsed time and look for patterns.

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.

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

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.

Seventh graders study elapsed time, radioactive decay and half-life.  For this time machine lesson students complete several activities and view a presentation. 

Science learners discover that scientific advancements come in increments. Beginning as an idea, changes and developments are influenced by available resources and current societal values. As an example, pupils examine the conclusions...

Learners gather data, make and share predictions about the time of sunrise ans sunset in their area. Patterns are analyzed and shared with students from other areas.

Students explore what radioactive decay is and are able to relate it to the concept of half-life. They are given 100 green beads that represent radioactive atoms and 100 white beads that represent stable, non-radioactive daughter atoms....

Young scholars study the laws of reflection using light beams and mirrors. In this reflection lesson, students work in teams to direct light beams to targets around the classroom. Young scholars use mirrors to change the beam's path and...

Students construct a car based on directions given. In this physics lesson, students calculate average speed using distance and time information. They collect data and create a graph of distance vs. time.

Students explore Newton's three laws of motion using a variety of activities. In this physics lesson, students calculate the average speed of a vehicle they constructed using distance and time information. They identify and draw the...

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...

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.
