An interactive tool where students can create a model of a greenhouse and use a light sensor to measure the amount of light it receives from a lamp at various times of the day. Temperature is also measured. Data is plotted on graphs,...

If you have ever had to adjust to a new time zone, you have noticed that it takes a while before you start to feel normal again. By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms....

Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this...

The article explains temperature. Specifically, you will learn about the temperature scale, temperature scale conversions, and the types of instruments used to measure temperature. Included are solved examples and interactive problems...

Based on experimental observations, students describe, on the molecular level, why the liquid in a thermometer goes up when it is heated and down when it is cooled.

If you're lucky enough to live in a place that gets snow in winter, you know that the feel of the snow can vary a lot. Sometimes it can be light and fluffy, and other times heavy and wet. This project shows you how to use data from daily...

Students practice the engineering design process as they explore devices used to measure changes in temperature. They work in teams to design, build, test, and evaluate their own temperature gauge made from everyday materials.

In this science fair project, use an infrared thermometer to measure the temperature of differently colored paper exposed to sunlight, and calculate energy emission using the Stefan-Boltzmann equation. Find discussion questions, a list...

Learn that temperature measures average kinetic energy, and heat is the transfer of energy from hot systems to cold systems. Consider what makes a good conductor. (Requires Java)

See how thermometers measure temperature by the molecular movement of the liquid inside.

To survive, we need oxygen in the air we breathe. Oxygen is also essential for most aquatic organisms, but there is much less oxygen available in water than in air. Learn how to measure dissolved oxygen and then see how oxygen...

For this activity, students will be given a set of materials: cardboard, a set of insulating materials (i.e. foam, newspaper, etc.), aluminum foil, and Plexiglas. Students will then become engineers in building a solar oven from the...

Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to...

This resource explains the structure of the metric system of measurement; the basic units of measurement for length, volume, and mass; and provides charts for each type of measurement. A chart of customary US units is also given.

Learn about the life and work of Anders Celsius, the Swedish astronomer who proposed the Celsius temperature scale which bears his name.

This is a straightforward, fun project to measure the rate of the chemical reaction that occurs when Alka-Seltzer tablets are plopped into water. You'll track the volume of carbon dioxide gas produced at regular intervals after the...

Lesson plan that allows students to investigate the effect of water temperature on fish behavior. Students measure, collect data, and interpret the results.

Instructions for how to make an electrical thermometer. The electrical thermometer works like this - the design consists of four resistors each made from about 40 meters of very thin copper wire. The electrical resistance of wire changes...
