Amazing Transpiration
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.
Curated OER
Density - To Float or Not to Float? That is the Question!
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.
Curated OER
Triangle Explorer
Learners compute the area of triangles in a computer program. In this measurement lesson plan, students complete 5 easy, 5 medium, and 5 hard problems.
Curated OER
Skills Review Worksheet
In this skills review instructional activity, students answer 10 questions that spiral review volume, unit conversions, perimeter and area of an irregular figure, and sketching views from a base plan.

A Galactic Fact Sheet
For this galactic fact worksheet, students read through important facts about galaxies, their shapes, and distances from the Sun.
Curated OER
Perimeter
Students explore the concept of perimeter. In this perimeter lesson, students discuss how to find perimeter of various shapes. Students use the Perimeter Explorer applet to find the perimeter of various shapes.
Curated OER
Hickory Dickory Dock
Students follow written directions to construct their own tangram. In this tangram instructional activity, students use their tangram to develop original figures that illustrate characters and/or objects from their favorite nursery...
Curated OER
Perimeter
Students use their hands, feet, computer, and rulers to measure the perimeter of objects. In this measurement lesson plan, students measure objects around the room and computer generated shapes.
Curated OER
Shape Toss
Students get a bounce ball and find a Polyspot. On the teacher's signal, students underhand throw to a target. They keep their own score: one point each time they hit a target.
Curated OER
Polygons, Pingos, and Themokarst! Oh MY!
Students complete activities to learn about the common land features in Alaska. In this land study instructional activity, students study an overhead for permafrost features. Students define ice wedge polygons, thermokarst, and pingos....

Density Column Lab - Part 1
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.
Teach Engineering
Density Column Lab - Part 2
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 liquids...
