Showing Results for comparing sizes

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!

Get estimating with this spooky activity that asks your young mathematician to rely on their problem-solving skills to figure out how many items they believe are in spooky Halloween jars!

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

Help your child learn science and math skills like sorting, sequencing, and ordering while taking a nature walk and collecting and collaging leaves.

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

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

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!

Invite your kindergartener to explore the bright new world of measurement by starting out with nonstandard (and tasty!) units, such as gummy bears or worms.

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.

A fun activity for a hot day, this will give young kids a chance to experiment with beginning science and math â and splash around in the process!

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

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

This science fair project idea discovers the effect of (high) heat on animal cells.

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.
