Participate in the investigation of a virtual crime scene using chemistry concepts to solve a mysterious death. The 40-50 minute activity can be used as a classroom lab or as a homework assignment. Additionally, teachers may request a...

Discover the many disorders associated with obesity, and learn how this epidemic affects us in today's society.

Students explore Hooke's law while working in small groups at their lab benches. They collect displacement data for springs with unknown spring constants, k, by adding various masses of known weight. After exploring Hooke's law and...

By the end of this section, you will be able to define net force, external force, and system; understand Newton's second law of motion; and apply Newton's second law to determine the weight of an object.

Want to lose weight in a hurry? Just step on a scale on almost any other planet! This page allows you to enter your weight on Earth and it will calculate your weight on all of the other planets, some moons and even some stars. Requires a...

[Free Registration/Login may be required to access all resource tools.] Convert metric units of length, mass, or capacity by multiplying by powers of ten.

A lesson where students collect trash, sort, and record the mass in grams. They will use their knowledge of numbers to figure out what category of trash had the most. The biggest idea of the lesson is that students will be more likely to...

[Free Registration/Login may be required to access all resource tools.] For this learning module, students must subtract mixed metric units of weight. Includes video demonstrating a sample problem [0:53] and a set of practice questions.

An interactive simulation with weights and scales that teaches about balancing chemical equations and conservation of mass. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional...

Newton's three laws are deceptively simple, but they are the underpinning of all of physics and govern the mechanics all of your actions in everyday life. Take an in-depth look at these laws in this learning module.

The Center for Mathematics and Science Education at the University of North Carolina at Chapel Hill provides an interesting and easy-to-use dictionary of the history and meaning of many measurement terms. Metric, International, and...

Conversion calculators galore! Convert just about anything from one measureable unit into another measureable unit here with over two dozen calculators. Each of the links is specific to a measureable quantity. Some examples include...

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

Weigh five little creatures on a metric scale, and subtract to find the mass to the hundredths place for each. A timer calculates your speed of computation.

Use this converter to find equivalent units for a measure. You can convert measures for area, length, weight, temperature, and volume.

Discussion of molecular formula and how to determine it from empirical formula. Practice problems are available.

This online textbook chapter provides learners with advanced-level reading and practice material on stoichiometry

This interactive game gives you a variety of measuring tools and measuring opportunity. For this game of chance you choose the correct tool for the job that needs to be measured. Everything you need for this game is listed and/or...

In this science lesson students will be asked the question, "Does air take up space?" and "Does air have weight?" Students will conduct experiments that prove that air has mass, takes up space, and exerts pressure.

It's difficult at times for younger students to realize that air has mass. Matter is something that has volume (takes up space) and has mass (*can be weighed). Air does take up space, even if we can't see it, and air has weight, even if...

A huge collection of teacher resources to aide in the teaching of all types of metric measurement: length, distance, mass, weight, capacity, and volume. Activities include measuring, estimating, converting, investigating, and finding...

This site contains an extensive list of various units of measurement known internationally and across several disciplines. Unit symbols are also included.

Students explore the creative process and understand the invention/innovation process through examining how paper bags are constructed. Teams of students work cooperatively to design, innovate, and then build their own paper bag models...
