Sort the pictures into three categories – solid, liquid, and gas. Cut, sort, and glue.
Science Stars: 1st Grade Lesson Plan States of Matter: Making Ice Cream Standards: 1.a. Students know solids, liquids, and gases have different properties. b. Students know the properties of substances can change when the substances are mixed,
Next, we select a constant pressure P 2 and gradually increase the temperature. There are two phase transitions: We first pass from the solid phase into the liquid phase, which is called melting, and then we pass from the liquid phase into the gas phase, which is called evaporation.
of aluminum. Starch, lime, and sodium sulphide are some examples. Cryolite, a chemical compound composed of sodium, aluminum, and fluorine, is used as the electrolyte (current-conducting medium) in the smelting operation. Naturally occurring cryolite was once mined in Greenland, but the compound

Aerogel is a synthetic porous ultralight material derived from a gel, in which the liquid component for the gel has been replaced with a gas. The result is a solid with extremely low density and low thermal conductivity.
Let’s find out whyWhat happens to water as it changes from a solid to a liquid to a gas? The changes from a solid to a liquid to a gas or from a gas to a liquid to a solid are called a phase changes.
Learn about solids, liquids and gases as you experiment with the conditions that change them from one form to another in this fun, interactive science activity. Water is a common example as it exists in all three forms, you’ve no doubt seen it as ice, liquid water and steam. Challenge yourself to
At the start of the unit I got the pupils to brainstorm everything they know about solids, liquids and gases on A3 sheets. From them, I compiled this powerpoint ‘quiz’ to address and question their ideas as a whole class activity.
One of the most basic things we are taught in college science classes is that water can exist in three different states, either as solid ice, liquid water, or vapor gas.
