Unit reasoning helps us make sense of measurements by converting between measurement units and making reasonable estimates. For the Praxis test, we need to know common measurement units for length, time, volume, and mass, as well as how...

The universe goes beyond the sun. Scientists study the amount of mass in the universe, but they also need to measure it in the far outreaches of the universe that are in the dark. Find out how they measure the mass of the entire universe.

Students learn how to measure the volume and mass of an object and use that to compute density. They will then use that density to talk about experimental errors and accuracy of measurements.

In this activity, students measure the maximum slope at which grains are stable (the angle of repose). They explore how different properties of the sediment influence slope stability and lead to different slope failures (mass movements)....

Students are introduced to air masses, with an emphasis on the differences between and characteristics of high - versus low-pressure air systems. Students also hear about weather forecasting instrumentation and how engineers work to...

In this activity, students use a Dual Range Force Sensor to measure the weight of pennies. They understand the difference between mass and weight. Students also determine the difference in weight of an object on the moon, Mars, Saturn,...

By the end of this section, you will be able to define mass and inertia and to understand Newton's First Law of Motion: There exists an inertial frame of reference such that a body at rest remains at rest, or, if in motion, remains in...

Practice converting a metric measure of mass to a smaller unit. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice converting a US customary measure of mass to a smaller unit. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

When electricity became available to the masses, utilities needed meters to record customer usage. This early 20th century model resembles many in use today. (Java tutorial)

About how many cells are in the human body? The purpose of this task is for learners to apply the concepts of mass, volume, and density in a real-world context. Aligns with G-MG.A.2.

Students will measure the length, diameter, and mass of twelve cylinders made of the same element. The first set of measurements are made with a standard metric ruler and 0.1g balance. The measurements are then repeated using a Vernier...

This lesson will introduce students to measuring weight, mass, volume, and capacity using metric and cutomary units. This lesson plan was created by exemplary Alabama Math Teachers through the AMSTI project.

Students investigate the relationship between density of an object, its mass and its volume. They use mass and volume measurements to determine the density of pennies. They compare the density of pre-1983 and post-1984 pennies.

It's difficult at times for younger young scholars 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,...

Use this online tool to convert measurements of acceleration, area, density, electricity, energy, force, length, mass, and other measurable properties.

In this lab students will measure the energy of a bowling ball with vernier motion detectors. The students will calculate the energy of the ball at the beginning, mid point, and end of a bowling alley. Students will inquire about the...

Learners will create a gravity ball launcher to demonstrate their understanding of mass, force, momentum, and motion. The students will use critical thinking, measurement, and observation and analysis of data to make changes and improve...

Could the location of the Olympic host city have an effect on weightlifting events? This activity provides an interesting context in which to engage with weight, mass and gravitation, and is aimed at A-level students (grades 10, 11, and...

Students must find the value of the spring constant based on direct measurements of length.

Practice US customary length, volume, and mass problems that require expressing measurements given in a larger unit in terms of a smaller unit. Students receive immediate feedback and have the opportunity to try questions repeatedly,...

Students will have an opportunity to determine what makes everyday objects move. Students will be given objects and asked to make predictions on how far each object will move after they blow on it. Then they will measure the distance and...

This activity can be used to explore forces acting on an object, to practice graphing experimental data, and/or to introduce the algebra concepts of slope and intercept of a line. A wooden 2x4 beam is set on top of two scales. Students...

Practice reading a triple-beam balance to the nearest 0.1 g.
