Practice reading a triple-beam balance to the nearest 0.01 g.

A seismograph is a tool scientists use to record earthquakes and measure their strength. In this activity you will build your own seismograph using simple materials.

This resource provides information about obesity, and the importance of weight control.

Students will learn the concept of volume by determining the amount of sand that is needed to fill the long-jump pit at their school (or any rectangular- or square-shaped container). This lesson will explain the importance of knowing how...

A guide to support parents as they work with their students in unit conversions and problem solving with metric measurement.

Convert between metric measures of distance, volume, and mass. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

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...

Students work as physicists to understand centripetal acceleration concepts. They also learn about a good robot design and the accelerometer sensor. They also learn about the relationship between centripetal acceleration and centripetal...

In this unit, students learn the basics about weather and the atmosphere. They investigate materials engineering as it applies to weather and the choices available to us for clothing to counteract the effects of weather. Students have...

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...

Manipulate the mass of a weight and the length of string in this interactive pendulum simulation. Change the speed, friction, and gravity to make the pendulum swing change as measurements are displayed on the screen. Younger students can...

By the end of this section, you will be able to do the following: Perform unit conversions in both SI and English units, Explain the most common prefixes of SI units, and be able to write them in scientific notation.

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,...

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.

Students use a Conductivity Probe to measure change in conductivity during a chemical reaction and determine the equivalence point of the reaction They determine the mass of the product and calculate the molar concentration of the...

Students use the Motion Detector to measure the effect of air resistance on falling objects. They determine how air resistance and mass affect the terminal velocity of a falling object and then choose a force model that fits the data.

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 explore the concept of the mole as a measure of quantity. They build spreadsheets that allow them to convert between moles, grams, and atomic mass units for given quantities of everyday items, elements, and simple chemical...

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"...

Create an Atwood's machine and a modified Atwood's machine in this interactive. Change the amount of mass on either object, introduce friction forces, and measure distance and time in order to calculate the acceleration.

This lab is designed to have students discover the relationship between the work that is done by a force and the speed gained by the object experiencing the force. Students can adjust the strength of the force. They can decide how much...
