This lab demonstrates Hooke's Law with the use of springs and masses. Students attempt to determine the proportionality constant, or k-value, for a spring. They do this by calculating the change in length of the spring as different...

Students act as chemical engineers and use LEGO MINDSTORMS NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and...

For this biology classroom lab, students investigate the affect of soaking a Gummy Bear in water. They collect measurements of height, width, and mass before and after the soaking of the candy overnight. Students calculate % change for...

Disappearing Wetlands: Explore the relationship between mass, density, and salinity by measuring the mass and volume of four saltwater solutions of increasing strength.

Rainforests at the Crossroads: Use a TI-73 Explorer to become familiar with a graphical technique for measuring the amount of leaves Leaf Cutter Ants chew. Measure the mass of a chewed leaf and then find its area.

For this activity, students first work in groups to collect information about a set of pennies. They measure and record the mass for each one in a table using a spreadsheet program if possible. They also record its year and, for 1982...

Students observe the relationship between the angle of a catapult (a force measurement) and the flight of a cotton ball. They learn how Newton's second law of motion works by seeing directly that F = ma. When they pull the metal "arm"...

In these KQED Lowdown infographics, explore how adult obesity rates in the United States, as measured by body mass index (BMI), have dramatically changed in the past half-century. A circular graph and a pictograph depict data by decade,...
