Team Puzzles
Fourth graders work in co-operative teams of four to complete a puzzle. Each student initially works independently, and then the team jointly puts together the four shapes they have individually made, to complete the puzzle.

Oranges and Stopwatches
Students begin to recognize that objects have many measurable attributes. They examine how to identify and accurately measure attributes of common objects. Also Students report their measurement findings.
Curated OER
Measuring Up!
Students draw lines of certain lengths by using appropriate measuring tools. In this measurement lesson plan, students determine which measurement tools would be best to draw specific lengths to make a barn.
Curated OER
Squid Races
Students imitate squid propulsion using a balloon and experience Newton's third law: for every action there is an equal and opposite reaction. Various anatomical designs are tested and analyzed. They calculate the speed of each squid...

A Hilly Ride
Fifth graders investigate situations that show how kinetic and potential energy are exchanged. They determine how friction is a source of energy transfer from kinetic to thermal energy by experimenting with a car and track. They answer...
Curated OER
Crop Circles
Students calculate the area and circumference of a circle. In this geometry lesson, students solve word problems with circles and create formulas to calculate the area. They find the rate and complex area of a circle.
Curated OER
Ecology and the Conservation of Natural Resources
Students examine the components of ecosystems. They compare and contrast an ecosystem to an aquatic ecosystem. They examine a local ecosystem and discuss its components.
Curated OER
Why Are Cells So Small?
Students examine the relationship between cell surface area and the ability of materials to diffuse through a cell. They participate in an experiment in which they determine which materials diffuse easier than others. They complete...
