Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water. 

Through three activities, first-time physical scientists wonder at the properties of water. Freeze some soda cans and a container of water prior to the investigation to show that water expands when frozen. Lab groups experiement with...

Students are introduced to the basic states of matter: solids, liquids and gases. Through experimentation, students determine that liquids and solids have definite volume, that gases do not have definite volume, and that solids have a...

Young scholars explore the physical and chemical properties of matter including phase changes and physical and chemical transitions. Information gathered is imported into video and edited to produce a movie.

A problem from a chemistry textbook is posed on the screen. In this problem, ethanol is used to illustrate how much energy, in joules, is required to change a substance from a liquid to a gas. The boiling point of ethanol is given, and...

Review the states of matter with your second graders using this resource. Learners first review what they know about solids, liquids, and gases. Then, they fill out a chart to show what they have learned. Finally, they engage in a...

Learners explore the concept of evaporation rates in this evaporation rates lesson. They will try to identify the chemical that began a fire, perform an experiment where they use the evaporation rates to determine the unknown liquid, and...

Students investigate the properties of solids, liquids and gases. In this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...

In this matter and energy worksheet, students identify substances as solids, liquids or gases, they use the kinetic theory to describe the motion of particles and they explain the conservation of mass and energy when a substance changes...

In this chemistry worksheet, students read the information on Le Chatelier's Principle. Students apply the information read to determine the volume of increase or decrease in the given equations. Students balance endothermic and...

Here is the first of four experiments to differentiate among unknown liquids by their behaviors and properties. Pupils observe how different liquids respond to being placed on plastic and paper, and they take notes about their...

Blue-tinted water is added to unknown liquids that have been tinted yellow to find out how they interact. This is a memorable activity that is part of an investigation on the properties of liquids, which is part of a unit on the...

Students investigate the properties of plastic eggs filled with solids, liquids, and gases and use these observations to hypothesize whether a chicken egg is hard-boiled or raw.

Students explore physical sciences by participating in a class experiment. In this matter lesson, students identify the three forms of matter and their physical differences. Students utilize cookie dough to create a play dough like...

In this heat transfer and phase change worksheet, students experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

Students read about matter by creating an in-class diagram. For this chemical lesson, students  identify the properties of solids and liquids and discuss ways they can transform chemically and physically. Students define a list of...

In this water worksheet, students read a 1 page article on water, fill in the blanks of 3 words with their missing letters, fill in a crossword puzzle containing 5 clues about water and answer 1 short answer question. Students draw a...

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...

Sometimes a simple explanation is best when introducing new concepts. Identify the three states of matter with this presentation. Each slide provides a simple description and examples for each of the three states. Tip: Show students the...

What happens when solids are added to liquids? After reading an informative paragraph about solutions, learners answer six true/false questions regarding solutions, and what substances will dissolve into liquids they are mixed with. A...

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. 

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,...

Not only is this presentation on matter informative, it includes audio and links for further reading. Perfect for a learning center, whole class instruction, or independent work station, your kids will learn all about the properties of...
