Students estimate the area of states using the formulas for the areas of rectangles, squares, and triangles. In this geometric shapes lesson, students divide irregular shaped states into shapes. They use the formulas for areas of...

Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; students use grids to make and explain estimates within low and high ranges.

Measuring volume can be a mystery for 5th graders, but this hands-on activity gives the gift of discovery. The volume of simple rectangular solids and irregular shapes are calculated through various methods including displacing liquid in...

Middle schoolers comprehend how Landsat satellites orbit teh Earth to produce images. They comprehend the elliptical path of satellites. Students recognize that a different orbital path is needed for different satellites to perform their...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

  Learners observe a leaf and discuss the way that water is released from a leaf through its stomata.  For this water cycle lesson, students calculate how much water leaves produce from a whole tree.     

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

What constitutes a good soap bubble? In the second installment of a nine-part series, scholars apply their understanding of surface tension to soap bubbles. They experiment to determine the best solutions to use for the...

In this plant science instructional activity, students complete a crossword puzzle with 48 questions. They identify the different parts of a plant.

Students engage in a lesson plan that differentiates between right and wrong types of observations. In order to conduct the experiment they are provided with leaves and nameless objects with different designs. The two are compared and...

In this galactic fact worksheet, young scholars read through important facts about galaxies, their shapes, and distances from the Sun.

Learners investigate why some objects float or sink in water. For this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Fifth graders determine that carbon dioxide is a gas given off during respiration and that oxygent is the gas that is absorbed during respiration. They determine the air capacity of the lungs.

Students discover that sunspots are the result of intense magnetic forces on the photosphere of the sun by observing images from the SOHO satellite.

Students complete activities to learn about the common land features in Alaska. In this land study lesson, students study an overhead for permafrost features. Students define ice wedge polygons, thermokarst, and pingos. Students also...

Students are shown that numeracy is all around them. They use volume, and calculate the quantity of soil required to make a garden to given instructions. Students are asked how to calculate the amount of soil required for the garden.

In this Pacific Ocean worksheet, students read 2 pages about the Pacific Ocean and answer true and false questions. Students answer 10 questions.

Students map an actual local waterway. They create full color scale drawings that include windfalls, plant cover, streambed composition, and landmarks such as trees, boulders, and slumps. This is a long-term project that involves...

At its core, the LEGO MINDSTORMS product provides a programmable microprocessor. Students use the EV3 processor to simulate an experiment involving thousands of uniformly random points placed within a unit square. Using the underlying...
