Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Here is an attractive worksheet that walks chemistry learners through a review of aqueous solutions. There are matching, short answer, and multiple choice questions dealing with boiling and freezing points, precipitate, molality, net...

Students examine water. In this chemistry lesson, student examine the physical properties of water and how it changes from a liquid to a solid or a gas. This lesson contains links to a second and third complimentary lesson on...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...

Crazy fact—freezing liquid actually gives off heat! Young scholars investigate the transfer of energy when liquids freeze using a chemical heat pack. The heat pack gives off heat as its liquid core freezes.

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Students observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

Sixth graders study heat, temperature, and heat transfer. Using probeware, the teacher demonstrates boiling points. Students participate in experiments and record the beginning and ending temperatures and mass of objects. After...

Students differentiate the three states of matter. For this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

In this ice and water worksheet, students read about the energy needed to transform ice to liquid water. Students solve 3 problems where they calculate the energy needed to melt ice given different scenarios in space.

Learners observe the melting of ice and explore the basic physical changes that occur. They gain information of how different substances change the rate of melting. Students discuss the properties of water and ice, the definition of...

Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Who knew that learning about the states of matter could taste so sweet? This fun hands-on lesson plan captures the attention of learners as they use what they know about solids, liquids, and gases to create their very own batch of ice...

Tenth graders observe the processes of evaporation, condensation, melting, freezing, boiling, and sublimation. They do a quantitative investigation of the freezing of water, to explore explanations that involve particles.

Students experience problem-based learning as they use prior knowledge of the states of matter to keep a frozen juice bar from melting.

First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

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...

Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

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.

solid, liquid, and gas. The three different forms of water are the subject of the article used to assess reading comprehension. After reading the article, kids respond to a series of comprehension questions based on the text.

In this recognizing the water cycle cloze activity worksheet, students use the words in the word box to fill in the blanks about evaporation, condensation, precipitation, and runoff. Students write 23 answers.

First graders conduct a science inquiry by comparing water in its liquid and solid form. The students describe the different stages of water and complete a worksheet answering questions about each form of the water. Teacher assessment...
