Students determine which wind-up toy is the fastest. However, they can NOT race the toys. They must find another way. On the first day of the activity, students work in pairs or small groups to develop and write a plan.

Students observe falling objects. They discover the rate of falling is based on air resistance and not the weight of the objects. They discuss how engineers use this type of information to design aerodynamic shapes.

Students design and build a car that is capable of traveling across the floor quickly, and also up a steep ramp.

Students design and build a snowplow using LEGO materials. They compete in an Engineer's Challenge to clear a path through Styrofoam peanuts.

Young scholars use Legos to build representations of a variety of numbers. They then sort and order their representations and pair them with the written number.

Students build Lego cars which have two different types of tire surfaces. They roll them down ramps that have both rough and smooth surfaces to determine how friction affects the car as it rolls.

Students participate in guessing their partners' hidden Lego pieces from their verbal clues. They work in partners to accomplish their goals. They are meeting a variety of math standards by completing this lesson.

Student design and build Lego vehicles that drag given amount of weight up an incline. They show how this demonstrates Egyptian methods of pyramid construction.

Students listen to the book "Henry Builds a Cabin." They design a cabin using Lego pieces based on information from the story.

Students explore optical illusions. Using Legos, they construct and motorize a machine that has an axle that's geared up and geared down, complete a worksheet, and answer discussion questions.

Pupils participate in a hands-on activity to explore the relationship between the number of batteries in a series circuit and its voltage. Students identify the relationship between two variables and plot points on a graph.

Students conduct tests of water samples from different sources, such as a local river, tap water, and an irrigation ditch. After determining which pollutants are present in each sample, students hypothesize the possible sources of the...

Students explain how satellites help scientists to see more than with the unaided eye and how Landsat technology works. Students identify vegetation and fire sites in the rainforest and detect erosion along rivers. They are able to use...

Students will observe the differences between photosynthesis and cellular respiration. Then they observe the links due to climate changes and relate how climate change affects their lives.

Students develop code systems to transmit information between groups. They explore, explain and apply techniques used to transmit remote sensing data to better understand remote sensing images.

Students share what they comprehend about the space shuttle program. They are given information about the first space shuttle mission. Students work in groups to investigate the different shuttle missions from April 1981 through January...

Students collect and analyze data.  In this middle school mathematics/science lesson, students collect temperature reading over a 24 hour period.  Students analyze the data for mean, median, maximum and minimum.

Students discover the factors affect friction. Students, working in lab pairs, complete various experiments in order to discover what factors effect the amount of frictional force a block has as it is pulled across different surfaces.

Students answer questions for each of the graphs and record their answers on the Student Observation Sheet. They use the data they have collected, hypothesize which graph represents which month of the year using each graph. They then...

In this moon worksheet, students review the different spacecraft missions that went to the moon and the information learned about the moon from these travels. This worksheet has 11 fill in the blank and 2 short answer questions.

Fifth graders complete a construction project.  In this pneumatic system lesson students study the basic hydraulic systems and construct their own project. 

In this English worksheet, students read " Record Bank Robbery in Brazil," and then respond to 47 fill in the blank, 7 short answer, 20 matching, and 8 true or false questions about the selection.

In this English worksheet, students read "Shuttle Discovery Launches Successfully," and then respond to 47 fill in the blank, 7 short answer, 20 matching, and 8 true or false questions about the selection.

In this preposition worksheet, 6th graders study a list of given prepositions. Students then respond to 45 fill in the blank questions supplying the correct preposition for each.
