Investigate equivalent fractions with your class. They compare and order fractions. Then they work cooperatively in groups to experiment and problem solve with fractions using a game format. Multiple resources are provided.

Get things moving with this elementary science unit on simple machines. Through a series of nine lessons including teacher demonstrations, hands-on activities, and science experiments, young scientists learn about forces, motion,...

Second graders sped the day exploring about balance by playing with and making balancing toys. They discover how varying the amount and position of mass affects the toys' balance. Pupils explore gravity and balance while playing with the...

Scientists use ice core samples to obtain temperatures of the earth from 400,000 years ago! The third of five lessons instructs pupils to interpret historical climate data to see changes over time. In part I, participants interpret...

Once junior ecologists are familiar with Earth's major biomes, they hone in on Arizona's biomes. Using a website about Arizona's natural resources, learners will identify biotic communities. Beautiful maps and worksheets are provided for...

Go on a moon mining expedition from the safety of your classroom with this space exploration simulation. Using simple models of the moon's surface prepared ahead of time by the teacher, young scientists are challenged with locating and...

Learners use materials to build, investigate, and draw two-dimensional shapes (polygons). They combine the shapes they have built and draw from the pile to begin a round-robin activity to name and determine the attributes of a selection...

Young geometers investigate two-dimensional figures using coordinate grids. They identify polygons and draw examples of their reflection, rotation, and translation on a coordinate grid. And they complete a worksheet practicing examples...

High School geometers verify through experimentation certain properties about dilations. This multi-step problem challenges them to construct examples of dilations to verify specific facts, the final step provides an opportunity to more...

Are these two light sources the same? Groups use a white card and a little cooking oil to create a photometer that allows for the comparison of two lights. The Inverse Square Law provides a way to calculate the actual difference in...

Compare heating and cooling rates of different land forms. A lab activity has groups collect data on the rate of heating and cooling of soil, grass, saltwater, fresh water, and sand. An analysis of the rates shows how the different land...

Tiny particles can provide big learning opportunities! Middle school scientists explore the world of nanoparticles through reading, discussion, and experiment. Collaborative groups first apply nanotechnology to determine water...

Students examine how Christopher Columbus determined his latitude.

In this motion activity, students complete motion word problems where they explain and define issues having to do with motion. Students complete 32 problems.

Collections of data represented in stem and leaf plots are organized by young statisticians as they embark some math engaging activities.

Ron Toomer, a famous roller coaster designer, suffered from motion sickness. Pupils design their own roller coasters, learning about potential and kinetic energy in the process. Labs focus on the importance of drop height, energy...

Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...

Beginning with a brief history of our 26th president, Theodore Roosevelt, then followed by a discussion of his interest in nature, young scientists take to the outdoors to locate and observe local plants and insects....

Students work with "ice" in order to gain a practical application of math concepts that evolve into an inquiry-based study. They determine if the dimensions of the ice make a difference in the way the ice floats in the water.

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...

Students examine the importance of good quality safety gear. In this investigative lesson, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design a...

Sixth graders participate in a lesson plan that is about investigating the different layers of the earth and defining how the plates move over the mantle. They engage in a variety of activities and use mathematics to create projects to...

Students model the transmission of neural impulses with dominoes. In this nervous system lesson, students construct a device with dominoes. They use the device to model the way a nerve impulse is propagated from dendrite to axon.

Students create a sundial and track the movement of the sun throughout the day. Modifications to the lesson are provided for both lower and upper elementary students.
