Fifth graders investigate chemical reactions. In this physical science lesson, 5th graders make dry ice root beer and identify the type of change that occurs to the root beer mixture.

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...

Second graders discover what changes occur in various types of matter under different conditions. They make predictions about the changes in an apple left out in the air, water placed in a freezer, and a nail left in a cup of water. They...

Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe water evaporating from an open container and water evaporating and condensing in a closed container. The students assess that a...

In this chemistry review worksheet, students answer a variety of questions about matter, elements, the kinetic theory, chemical and physical properties and the distillation process. They complete a concept map about matter.

Middle schoolers utilize their knowledge of the physical properties of matter such as mass, volume, and density to solve a problem. They utilize the scientific method to solve a problem. Pupils analyze their data to determine whether...

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.

Third graders understand that the smallest particle is an atom. In this matter lesson, 3rd graders make a piece of aluminum smaller and smaller to see that what's left is still aluminum. Students recognize that cutting into smaller...

Learners investigate the three states of water. In this physical science lesson, students watch the video "Earth's Ecology" and observe water in its' three states. Learners record observations.

Ninth graders discover the reasoning behind spraying water on fruit and seedlings in preparation for hard freezes. In this conceptual physics lesson, 9th graders conduct an experiment to measure the heat released when water goes from a...

There are so many topics touched upon in this Jeopardy-style science game, that it is difficult to classify! The categories include electricity, matter, ecology, earth and space, and scientific investigation. This would best be used at...

In this matter activity, students identify words and match them to their definition. Students identify words dealing with matter, its physical changes, and the effect of heating and cooling matter. This activity contains nine matching...

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Students explore the physical process of melting. They observe melting ice and answer questions related to energy transfer during phase changes.

Students investigate how information about the atom has been determined. In this atomic structure lesson, students draw what they think an atom looks like. They conduct Internet research about the types of atomic models and how...

In this matter worksheet, students read statements about changes happening to matter and classify the change as either a physical or a chemical change. This worksheet is a graphic organizer.

Students observe changes in water. In this lesson about water and its forms, students perform an experiment to determine how water changes. Students analyze what causes water to be solid, liquid, or gas. Students record their...

Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Chemical and physical properties give compounds an identity. Learners use the identity of a compound to predict what it is. By performing different tests like solubility, flame, heat, and reactions, individuals attempt to identify an...

Second graders identify physical and chemical changes of matter. They distinguish between physical and chemical changes. They classify changes as physical or chemical.

In this matter worksheet, students answer ten questions about matter including the phase of matter, mixtures and how they are different from compounds, the physical and chemical properties of matter and the difference between homogeneous...

In this matter and chemical changes worksheet, learners write symbols and formulas for 2 chemical reactions. They write words for 1 chemical reaction given in symbols and formulas. They draw a diagram representing a chemical reaction and...
