Young scholars 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...

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...

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.

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.

High schoolers 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...

This metric system tutorial is compared to the U.S. standard system so that students can comprehend the measurement of length, volume, mass and the like.

[Free Registration/Login may be required to access all resource tools.] Choose appropriate tools and metric units for given items and measurement situations.

[Free Registration/Login may be required to access all resource tools.] Choose appropriate metric measurement tools when finding various lengths.

Decide whether you want to measure in Standard or metric and at what level (i.e. inch, half inch or centimeter, millimeter) and begin practice. Computer will generate a line above the ruler and the player enters the length and checks for...

In this lesson plan site, students will learn how to use a metric ruler to measure length, accurately read and record measurements taken in centimeters and millimeters, and collect and analyze data using a stem and leaf.

Practice using metric rulers and rulers with inches. Includes helpful feedback when questions are answered incorrectly.

This interactive activity gives young students practice measuring lines with a ruler using centimeters.
