Students measure and label specified angles. In this angles lesson, students use a protractor to find angles that are acute, obtuse, and reflexive. Students then label each angle and match the angles the correct definition. This lesson...

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...

Kids observe, classify, and measure tree leaves with a scientific eye. They examine leaves, group them according their attributes, and use standard units of measurement as they compare their sizes. They access a web site to learn how...

How are skyscrapers built? What does it take to make a structurally sound building? How can one work within a budget to complete a building project? These guiding questions will be investigated and answered within a hands-on...

In this 2-D shapes lesson, kindergarteners review plane shapes attributes. They engage in a shape hunt in the classroom and create art using plane shapes. A good, hands-on lesson!

Can you see your class working on spatial visualization? The first installment of a five-part module introduces the concept of spatial visualization and provides a 12-question diagnostic assessment to test spatial visualization skills....

Second graders are introduced to different types of motion. They make rolling spider toys and race them on different surfaces to invsetigate forces and motion. Pupils make glue "spider webs" for their spiders after testing different...

Students construct a rocket from a balloon propelled along a guide string. They use this model to learn about Newton's three laws of motion, examining the effect of different forces on the motion of the rocket. They measure the distance...

Students explore aerodynamics and Bernoulli's principle by devising ways to keep bubbles aloft.

Young scholars engage in an activity which demonstrates how potential energy (PE) can be converted to kinetic energy (KE) and back again. Given a pendulum height, students calculate and predict how fast the pendulum will swing by...

Aim high with a task on window washers. An assessment task challenges learners to determine the number of windows two people wash. They do this using a given number of window rows on each side of a building. In addition, they find the...

Students build and compare models of both an energy inefficient and efficient classroom. In this energy efficiency lesson, students creatively use recycled materials to build two separate classroom models. They factor in concepts such as...

Students enjoy making 3-D figures while learning about rectangular prisms, pyramids, vertices, edges, and faces. After a lecture/demo, students use marshmallows, toothpicks and a worksheet imbedded in this instructional activity to...

Students measure the mass, volume, length and area of various objects. They are assigned a letter. The task is assesses students' abilities to make simple observations and measurements.

Students create spectral colors. In this hands-on science lesson, students examine the electromagnetic spectrum as they follow steps to create a model that separates and displays light.

Students identify the properties of solids and polygons. For this geometry lesson, students identify the different measurements of a triangle. They use congruence parts and theorem to prove their answer.

Children use the length, width, and height of an object to calculate the volume of a rectangular prism. They observe how to multiply three numbers at a time, and define volume. Pupils observe as the teacher demonstrates how to determine...

Students explore measurement. They use appropriate units of measurement for different sized objects. Students collect their data and enter it into an Excel data base. They graph their findings and analyze their outcomes.

Students explore the tools used by Columbus to chart his latitude. They study the change of a location over time.

Origami is an excellent way to combine Japanese culture, art, and geometric shapes into one engaging instructional activity! Scholars begin by listening to the story Sadako and the Thousand Paper Cranes and learn the origin of...

Students describe properties of liquids and use descriptive language as a springboard to develop precise vocabulary for properties of liquids. They also use vocabulary as practiced with liquid-vocabulary card games. Finally, students...

Young scholars participate in a qualitative discussion of the distinction between weight and mass, followed by a description of astronaut mass measurements in a zero-g environment.

Students make observations about mealworms using hand lenses, rulers, and cotton swabs. Students complete their own mealworm observation chart, then they share their observations with the class. This is one station out of five in an...

Fifth graders study environmental changes by examining the annual rings of a cross-section of a tree trunk. They access websites to complete a worksheet on the parts of a tree. They count the annual rings on a tree slice while observing...
