Sixth graders discover the difference between weight and mass. In an experiment, they examine the Law of Conservation of Mass in action and discuss if a physical change causes a change in mass. They observe chemical and physical changes...

High schoolers explore measurement and units. They measure eggs to determine their density, mass and percent composition. An inquiry approach is used for students to ascertain the mass.

Young scholars inquire into how the center of mass is the key factor in designing cars. They construct an oddly shaped object and determine its center of mass. They find that engineers are able to predict how objects will behave while...

Students work together to discover the concept of angular momentum. They participate in experiments in which they test rotation and relate it to an object's mass. They participate in a literacy activity in which they compare mythology...

Students explore the concepts of center of mass and static equilibrium by seeing how non-symmetrical objects balance. They also analyze why all forces on an object must cancel out exactly for an object to be stationary.

Students research the development and implementation of a research vessel/vehicle used for deep ocean exploration. For this oceanography lesson, students calculate the density of objects by determining the mass and volume.

Students parcticipate in a modeling activity that simulates the cyclical role of experimental and theoretical science. Initially, students measure the mass of popcorn. They also record predictions of the mass of the kernels after they...

Young scholars use an Excel spreadsheet to calculate the density various liquids. They take pictures of their results.

High schoolers create balloon and rubber band models of robotic rovers to investigate the concepts of mass, torque, and friction. Through research and planning, students construct a rover test-bed that simulates the Martian environment.

Fourth graders, in pairs, explore the relationship between a star's life and its mass. They use a concept map to illustration the three categories of stars.

Fourth graders see how, when balls are dropped from the same height, mass and size affects the motion of the balls.

Students explain the basics of rocketry and explain the relationships between mass, acceleration, and thrust.

Students conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.

Young scholars demonstrate an understanding of the text by completing a propulsion activity, charting the results, and answering questions that demonstrate an understanding of rocket propulsion.

Chem4Kids! provides an overview of the symbols representing numerical values in chemical equations. Each symbol is defined and described.

[Free Registration/Login Required] Learn about Newton's 2nd Law- the relationship between force, mass, and acceleration, for a wind-powered boat.

[Free Registration/Login Required] Uncover the relationship between weight and mass, on Earth and beyond.

In this student-paced module, students apply Newton's Laws of Motion to everyday life, calculate mathematical relationships involving force and motion using algebraic formulas, and understand the difference between mass and weight.

This interactive resource from the Exploratorium calculates your weight on other bodies in our solar system and offers an explanation of mass and weight and the relationship between gravity, mass, and distance.

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...

This project presents an interesting puzzle. A disk of wood will float face-up, that is, with its circular cross-section parallel to the surface of the water. A long log of wood, however, floats with the circular cross-section...

In this earth science lab, middle schoolers will find, identify, and create a visual presentation of the rocks that are found around their school. They will determine the mass, volume, density, color, texture, and hypothesize what each...

In this activity, students will use a plywood ramp and various tornado tubes (made from tornado tube connectors and 2 liter pop bottles) to calculate the average speed of the tornado tubes. They will set up 4 investigations filling the 2...

In this lesson, students will investigate why the Cartesian diver dives and rises in a 2 liter bottle. They will also, through their own discovery, come up with a question and then change one variable and record their results. Students...
