Beware the falling fruit. Scholars design and build parachutes that can help protect fruit as it falls. They test out their creations, learning about gravity, weight, air resistance, and measurement concepts along the way.

Why do you weigh more in space? Each individual in your class explores this question and others as they determine the mass and weight of different objects using two types of scales. They perform conversions and discuss their...

Bend it, but don't break it. Groups investigate the strength of different materials. Using a procedure in the seventh segment of a 22-part series on aviation, pupils determine how far a rod will bend. They determine the strength-to-mass...

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

Slide books with a little assistance from Newton. Using books, groups create a demonstration of Newton's Second Law of motion. Pupils compare the distance traveled by one and two books when they apply a force to them.

Stop and drop what is in your hand! Pupils investigate how form effects drag in the 12th part of a 22-part unit on aviation. Groups create equally weighted objects and determine which one falls the fastest by collecting data.

Get into the swing of things. Pupils use a pendulum to demonstrate the conversion of potential energy to kinetic energy and back. After measuring the speed of a pendulum and compare it to the calculated theoretical speed, they...

Create an egg-citing study of energy. Pupils investigate the effect of height and mass on the overall amount of energy of a falling object. The fourth segment in a six-part series on energy uses a weighted egg falling from different...

If you have a rotating office chair in your classroom, you can have physics pupils participate in this simple, yet effective demonstration of angular momentum. One partner sits in the chair, arms outstretched, holding heavy weights. The...

Test the limits of gravity while encouraging full class participation with this thrilling lesson. Pupils investigate the meaning of work and how it is equivalent to energy. They explore the joule and apply it as a unit of work. They...

The last segment of the nine-part unit makes a connection between springs and linear equations. Groups hang weights from the spring and measure its length. Then, using the data collected, they calculate the slope to find the k-value...

Every child's dream: stuffing as much candy into a bag as possible. Doing this, though, requires a nice sturdy bag. Scholars design the sturdiest bag they can and test the limits of those bag using a sweet treat!

Scholars build robotic arms that swing back and forth and use them to collect velocity and acceleration data. To analyze the results, pupils compare data to the equations for angular velocity and centripetal acceleration.

The learning activity explores weight. Students weight different items and compare their mass from smallest to largest.

Students learn about standard units of mass. Topics include ounce, pound, and ton. Practice problems are included to check for comprehension of the concept.

This site allows you to convert weight/mass measurements. For example converting tons to grams. CCSS.Math.Content.3.MD.A.2 Measure and estimate liquid volumes and masses of objects using standard units

If you like tackling formulas, then this math challenge is for you. See if you can calculate Helix's BMI (body mass index) and find out if his health is at risk. A one page NCTM Math Challenges for Families activity that engages learners...

Students learn the difference between weight and mass. Practice problems are included to check for comprehension of the concept.

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...

Grams, kilograms and tonnes are explained, and real life examples are given for each.

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

Students learn about the concept of pushing, as well as the relationship between force and mass. Students practice measurement skills using pan scales and rulers to make predictions about mass and distance. A LEGO MINDSTORMS NXT robot is...
