In a fun lesson, kids learn about states of matter by identifying solids and liquids, then experimenting with gas to see if it has energy. Young scientists place raisins in a jar of club soda to see how the gas affects the floating or...

The first in a six-lesson mini unit, all using M&Ms® candies, this physical science activity gets kids to observe a single piece and discover what happens when it is placed in a plate of water. The activity can be used to introduce...

During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Solids, liquids, gasses oh my!  Young scientists will be amazed when they try this experiment, which uses dry ice to discover the states of matter through sublimation.  

Who knew that learning about the states of matter could taste so sweet? This fun hands-on lesson captures the attention of students as they use what they know about solids, liquids, and gases to create their very own batch of ice cream.

Fascinating reading about nanotechnology, nanoscale properties, and liquid crystals precedes a fun activity for young engineers. They measure their hands in nanometers, research, and then investigate how heat effects a sheet containing...

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-lesson unit on dissolving, this installment investigates the effect of temperature. If you consult the...

Fahrenheit? Celsius? What's the difference, and where did these two temperature scales originate? Your pupils will learn all about these topics by reading the passage included here. After reading, individuals respond to five questions...

Your physical science class learns that there are three states of matter, and that adding or removing heat can cause it to change from one state to another. By the animations, printed information, and discussion between RJ and Zoe, they...

Differentiate between temperature and thermal energy. Your class will build a thermometer using simple materials and develop their own scale for measuring temperature. Discuss with your class and consider why engineers need to understand...
