Water 3: Melting and Freezing

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

Young scientists investigate chemical and physical changes to the states of matter—gas, liquid, and solid—as well as solutions and suspensions with a variety of demonstrations, grand conversation, and an interactive quiz to check for...

Solids, liquid, and gas, the three states of matter, are the subject of a cross-curricular reading comprehension exercise that asks kids to first read an article about these forms, and then to respond to a series of questions based on...

Students participate in a science experiment to understand that matter takes up space.  In this matter lesson, students experiment with solids, liquids and gases to recognize that matter is everywhere. Students make observations and...

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

Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...

Investigate the properties of solid and liquid materials. This very complete slide show is perfect for introducing liquids and solids to children in grades one or two. It describes multiple properties of solids, metals, plastics, wood,...

Students explore solids, liquids, and gases. For this states of water lesson, students conduct a scientific investigation that requires them to observe and note the differences among solid, liquids, and gases.

Kids will have clarity in understanding the differences between solids, liquids, and gases. They Might Be Giants perform a catchy tune to help. [1:22]

Observe the differences between solids, liquids and gases.
