In this activity, students' will use temperature sensors to measure temperatures of water samples before and after mixing. They compare the mixing temperatures to a linear prediction.

In this week's Afterschool Adventure, Appetite for Fractions, children will explore fractions as they help create, divvy up, and serve a variety of real and virtual snacks.

In this activity, students' will use a Voltage Sensor to measure the voltage produced by an electrolyte. They will understand that acids and bases are electrolytes and compare voltages of acids to the voltages of bases. Students' will...

Students use the EasyTemp Probe to measure the temperature of hot and cold water before and after mixing. Students compare the mixing temperatures to a linear prediction. EasyData is needed for this activity.

In this activity, you will make a liquid thermometer to track how temperatures vary with location, indoors or outdoors.

In this video from Cyberchase, Bianca is babysitting infant twins. As she tries to give each twin the same amount of liquid baby formula, she discovers that all the baby bottles are different shapes. Learn how she finds two that hold the...

Here are three activities--concentration, matching, and flashcards--to help learn or review the units of customary measurement.

Students learn how volume, viscosity and slope are factors that affect the surface area that lava covers. Using clear transparency grids and liquid soap, students conduct experiments, make measurements and collect data. They also...

Students calculate the viscosity of various household fluids by measuring the amount of time it takes marble or steel balls to fall given distances through the liquids. They experience what viscosity means, and also practice using...

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...

Read the die to find out what exercise to do and how many repetitions are needed, keep a running tally of rolls to see who gets the highest score.

Use this site to find out how humidity works and perform some activities related to humidity.

Students determine the refractive index of a liquid with a simple technique using a semi-circular hollow block. Then they predict the refractive index of a material (a Pyrex glass tube) by matching it with the known refractive index of a...

Concluding a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate densities of several household liquids and compare them to the densities of irregularly shaped objects (as...

Students learn the importance of heat transfer and heat conductance. Using hot plates, student groups measure the temperature change of a liquid over a set time period and use the gathered data to calculate the heat transfer that occurs....

Students are introduced to the physical concept of the colors of rainbows as light energy in the form of waves with distinct wavelengths, but in a different manner than traditional kaleidoscopes. Looking at different quantum dot...

Students will study temperature changes caused by the evaporation of alkenes and alcohols and relate this data to the strength of intermolecular forces of attraction. They will also predict, and then measure, the temperature change for...

Surface tension accounts for many of the interesting properties we associate with water. By learning about surface tension and adhesive forces, students learn why liquid jets of water break into droplets rather than staying in a...
