Showing Results for comparing lengths

Compare air temperature with the infrared temperature from a reflecting surface at different times of the day, in shade and in sunlight.

How do cold packs work? Explore endothermic reactions by comparing the temperature change that results from various chemicals added to water to find out!

This measurement activity uses feet to compare objects, but not the ones found on rulers and measuring sticks...the feet on your child's own body!

This science fair project investigates how temperature of a room affects the burn rate of a candle.

Does your child love learning about dinosaurs? Does he like digging around in search of hidden treasures? In this fun activity he'll do both!

Encourage your child to compare and contrast a wide variety of autumn-themed items by weighing various objects and recording their findings.

Give your second grader a chance to get his feet wet with measurement before he moves onto the more complicated stuff by trying this activity with him at home.

The objective of this science fair project is to examine the cleanliness of salad preparation techniques.

Do plants breathe? Not exactly. They do respire though! This activity will help your child with see that plants are producing the oxygen we need to survive.

This project compares different liquids and the freezing, melting and boiling points of liquids.

This experiment works due to a simple principle: plants need light. Build a shoebox maze and watch the plant work though the obstacle course, searching for sun.

Determine how salinity affects the circulation of warm and cold water. Note whether the warm water mixes or forms a layer with cold water.

The objective of this science project is to determine the relationship between carbon dioxide gas and the temperature of the atmosphere.

Learn how to make a hygrometer to measure relative humidity in this project. Make a sling psychrometer hygrometer with gauze, thermometers, and a bottle.

Determine whether magic salt is more effective at melting snow than regular salt. Pour one ounce of salt over the ice cubes, compare the melt downs.

The purpose of this science project is to determine which chemical best lowers the temperature of water in a cold pack and if the amount affects its use.

This project concerns activity happening millions of miles away, on the sun.

The objective of this science experiment is to evaluate the affects of high and low heat capacity on a material's heat retention ability.
