Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.  

Students investigate various properties of ice including melting points and the effect of pressure on ice. They demonstrate how increased pressure lowers the melting point of ice and perform a simple experiment proving that water is more...

In this volume worksheet, students take notes on the various ways to measure volume depending on if the substance is liquid, an irregular shaped solid, or a regular shaped solid.

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. They describe how sound needs molecules to move and that changing the medium that it travels through changes the...

Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.

Student examine the physical changes of matter and are able to describe them. They make ice cream in plastic bags to observe the changes in matter. They describe and record the changes in the ice cream mixture as it freezes.

In this states of matter worksheet, students will write 2 things that cause matter to change state. Then, students will write in the effect that cause has on the state of matter.

In this properties and characteristics of substance learning exercise, students review and study six key terms associated with matter and then locate those six terms in a word search puzzle.

Students explore water and ice. In this 3 states of matter lesson, students work with a partner to observe, illustrate, and describe the characteristics of an ice cube in a cup. The ice cube is observed again in 15 minutes and changes...

Students examine water as it changes states.  In water and ice lesson students study the water cycle and what happens to it as it changes state. 

Students study the water cycle and the different forms of water.  In this exploratory instructional activity students observe, measure and describe water as it changes state.

Learners observe water as it changes form.  In this water lesson students observe, measure, and describe water as it changes state. 

Students identify the various states of water. They use hypothesizing and hands-on experimenting on changing the states of water, the properties of water, and the role of heating and cooling in the changes of state.

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Students observe the diffusion of air molecules through a balloon. In this chemistry and molecules lesson, students fill balloons with air and a scented substance and observe whether the scented air is able to permeate the balloon.

In this scientific models worksheet, students will use a model to represent matter in its various states. Students can use a computer graphics program, drawing on paper, or three-dimensional creation. Then students will complete 3 short...

Students discuss a given set of questions based on Chemistry and matter and review a glossary of terms. They conduct experiments on each state of matter: "Dry ice and water, Dry ice and soap and Dry ice and Isopropyl Alcohol." and...

In this thermochemistry instructional activity, learners indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Learners...

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

Learners explore the different phases of a crystal.  For this mineral lesson students grow their own sugar crystals using a sugar recipe. 

Young scholars observe crystals and their shapes and formation. In this crystal formation lesson, the teacher prepares crystal gardens for the students to observe, then the class finds examples of crystals in nature and observe a teacher...

Students use screens of three sizes to separate a mixture of five solid materials. They plan and conduct simple investigations using appropriate tools, measures, and safety rules and record and report observations, explanations, and...

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.

Third graders listen to a talk on phase transitions and view three demonstrations. In this phases of matter activity, 3rd graders complete a worksheet as they listen about phase transitions. They move through three demonstrations of...
