Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

Students study soil and how particle and pore size affect water movement.  In this soil lesson students complete a lab activity to investigate pore saturation and sponge like behavior. 

Students analyze density. In this density lesson, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Students examine the different flow rates of liquids and how lava's viscosity influences flow.  In this liquids lesson students complete several handouts and a lab activity.

For this solid, liquids and gas worksheet, students complete an on-line quiz, choosing questions and matching answers. Students score 1 point for each correct answer; a printed version is available.

In this tracing instructional activity, students trace sentences about solids, liquids, and gases. Students trace 9 sentences total on this instructional activity.

Students examine how water changes state, from a liquid to a solid.  In this water instructional activity students study the water cycle and how temperature and pressure effect it. 

Students observe what happens to water as it goes from a solid to a liquid.  In this exploratory lesson plan students gain an understanding for the water cycle while working in groups observing what happens to water as it 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. 

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

Fifth graders collaborate with other classmates to classify and create mixtures made of two or more substances. In this mixture lesson, 5th graders create solid-solid, liquid-solid, and liquid-liquid mixtures. Students discuss with the...

First graders experiment with different states of matter in order to observe the changes in matter. In this states of matter lesson plan, 1st graders see and explain how solids, liquids, and gases change.

In this science quiz instructional activity, students read and answer 5 short answer questions and 5 true and false questions involving different types of matter in science.

Students observe the melting of ice. For this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

In this changing materials worksheet, students fill in the blanks for questions about dissolving a substance in a liquid and particles in a solvent.

In this chemical change worksheet, students review physical changes such as evaporation and condensation before working with chemical change. They conduct an experiment with vinegar and baking soda before recording the chemical changes...

Students identify the three states of matter and their properties.  In this physical science lesson, students explore a website on the states of matter and complete a worksheet.

Students examine states of matter. In this solids and liquids lesson, students conduct a scientific investigation that requires them to make ooze and record their observations pertaining to it.

Students explore water. In this water cycle lesson, students conduct a scientific investigation that requires build a terrarium models of the earth. Students record their observations of the changes regarding water in the terrarium.

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...

In this solids and liquids worksheet, students analyze the table of melting points of common materials in order to answer the questions given.

Young scholars study the attributes of liquids. In this science exploration lesson, students participate in a hands-on activity that requires them to examine the volume and shape of liquid.

Learners explore the three states of matter. In this matter lesson, students are shown a variety of examples and decide whether it is a liquid, solid or gas. Learners brainstorm what characteristics the objects in each group share.
