Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

Learners compare slime recipes. In this properties of matter lesson, students make Oobleck and glurch and compare the properties of each and examine the solid and liquid properties of them.

Students differentiate the different phases of matter. In this chemistry lesson, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.

In this chemistry of ice cream worksheet, students investigate colligative properties and how they affect freezing points while making ice cream. Students answer short answer questions to determine if freezing is an endothermic or...

What does it take to be considered a smart material? Learners investigate the properties of Nitinol, a smart material, through a hands-on lab activity. They examine the crystal lattice structure and the conditions required for Nitinol to...

Students explore the definition of matter.  In exploring matter lesson students get into groups and navigate the Internet to answer questions. 

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

In this chemical equations worksheet, students identify the reactants and the products, state what phase each is in, and state the mole ratios of all the products and reactants. Students complete 10 problems.

Middle school chemists visit interactive websites in order to discover what happens to molecular motion when heat is added to matter. They conduct an experiment that demonstrates the expansion of matter with the addition of heat. A lab...

In this heat transfer and phase change worksheet, learners 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...

Young scholars experiment with balloons, soda water and raisins to find out about the states of matter.  In this solids, liquids and gases instructional activity, students complete a group activity with balloons to recognize the...

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. 

Students describe the motion of solids, liquids and gases. In this chemistry lesson, students describe how temperature affect motion of the particles. They determine the physical properties of each phase.

Students observe phase change of matter by making ice cream in bags. In this states of matter lesson, students work in pairs to churn their own ice cream in plastic bags. They make predictions about how long it will take for the milk to...

First graders explore the properties of matter. In this states of matter lesson, 1st graders conduct scientific investigations that require them to mix, cool, and heat objects in order to observe changes in the properties of matter.

Students investigate the concept of dark matter and how it occurs in the universe. They conduct research using a variety of resources. Students use the information by reading at least two articles about dark matter. They also generate...

Examine the effects of temperature and pressure on solubility and the states of matter of ocean water. Learners make inferences about the unique chemistry of ocean water at different depths. They engage in an activity related to...

Wow! This is a nifty presentation for teaching high school chemists about the heating curve. It displays a graph for temperature vs. heat added, then enters the curve itself. The final slide identifies each part of the curve. Notes are...

Learners examine the flow of water. They observe and test the properties of water by using sticks in flowing water. The lesson has streaming video, resource links to access, and a good hands-on activity that is clearly described in the...

Bored with your current biome bag of tricks? This bundle is a bountiful bag of biome fun! Travel the globe with seventh graders and explore the biotic and abiotic factors that define our world's biomes. Then, introduce a little...

Learners investigate refraction and reflection of light. In this light lesson, students perform 3 activities to observe light interacting with matter by using a flashlight. They explore refraction using a glass of water and reflection...

Learners categorize items into one of the three states of matter. They participate in a demonstration in which they represent particles of matter. Finally, they complete an experiment in which they "race" top see who can make acetone...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

For this matter worksheet, learners review the states of matter and the gas law formulas and equations. Students then complete 7 multiple choice questions and 6 problems.
