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...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

In this phases of matter worksheet, students complete 13 fill in the blank spaces with science words from the given word bank. The blanks are placed within an informational paragraph about solids, liquids, and gases. 

A teacher with talent has created a fun set of review questions on the changing states of matter. Cycle through 15 questions, multiple choice answers, and a monetary reward for guessing correctly. Use this game show PowerPoint to help...

After having a class discussion on the three states of matter, young scientists utilize the wonderful substance, Oobleck in order to experience something that changes states of matter. They also create "sparkle jars" which...

Little chemists address whether or not you can get sugar back out of tea after it has dissolved. The PowerPoint itself simply walks them through the questioning process, considering different possibilities. The final slide settles on...

Students explore the states of matter. They discuss the different phrases of matter and categorize everyday substances as solids, liquids, or gases. Students explore the relationship between the phases on an atomic level and the role of...

First graders are read a story about the various stages of matter with a focus on gases. Using a ziploc bag, they capture as much air as possible and discuss how it takes up space even though it is invisible. To end the lesson, they blow...

Using a famous children's story as the hook, learners explore the concept of changes in matter. First, they make a cake similar to the one made by Alice in the story Alice's Adventure in Wonderland by Lewis Carroll. Next, they let their...

Learners predict if icebergs melting has an effect on the sea level rising.  In this global warming lesson students complete an experiment to see the effects of melting icebergs and write a conclusion on their data collected.

Students experiment with the cohesion of water molecules. In this surface tension instructional activity, students estimate how many drops of water a full glass can take before overflowing. They watch a video that explains water molecules.

Students observe and explain how a change in temperature causes a physical change in a substance.  In this physical science lesson, students use a soap making kit to observe the effects of adding heat to the bar soap as they...

For this states of matter worksheet, students are given a summary of the particle arrangement, the motion of particles, the properties of particles and models of particles in solids, liquids, and gases. Melting, evaporating and boiling,...

Students examine the changes as water goes from solid to liquid. In this states of matter lesson, students observe and record the changes to water as it changes from solid to liquid and back to solid.

Students investigate common household items and classify them into types of matter. In this matter instructional activity, students group given items into categories based on their characteristics. They also complete a concept map about...

In this thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Kids complete the phase change diagram as well as define a given set of vocabulary words. Students calculate mass...

Students explore matter through the concept of displacement. They perforrm an inquiry experiment with a glass, paper and a bucket to demonstrate that gases take up space.

Fourth graders define the term matter. They compare properties of solids, liquids, and gases. They describe how matter changes from one state to another. They classify objects as either solid, liquid, or gas.

Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...

Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe what happens when they try to put two kinds of matter into the same space and conclude that solids, liquids, and gases occupy space.

Second graders identify and describe properties of matter. They identify three forms of matter- solids, liquids, and gases with 100% accuracy. The student describes the properties of solid objects.

Students examine the processes of melting and freezing.  For this matter lesson students complete a lab in groups, discuss what they learned and view a teacher demonstration. 

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.
