Learners observe experiments in density and describe the results. In the experiment, milk, corn syrup, and oil are added in different orders to three glasses, while one other glass contains only water. As objects are dropped into each...

Students conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases. Finally,...

Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

Learners examine the properties of a liquid that contains water and food coloring and a liquid that contains water, food coloring and a liquid detergent. They interpret their data, describe properties, and make reasonable explanations...

Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...

Second graders explore states of matter when they change a liquid to a solid. Working students make ice cream in a zip-lock bag.

Students examine the differences between snow and rain. For this precipitation lesson, students measure one inch of rain and snow to calculate the amount of liquid water. Students use a snowfall "conversion" chart to measure how much...

Middle schoolers investigate water vapor. They view and analyze photos, conduct Internet research, and analyze the total water vapor/total liquid water data plot.

In these earth science worksheets student complete this project to model activity in the mantle, one Earth's four layers. The project includes liquid and powder materials in addition to several measuring components. Students must then...

Students determine the differences between the crystallization of igneous and metamorphic rocks. They examine both liquid state and solid state crystallization.

High schoolers are introduced to the laws of thermodynamics. The 1st law of thermodynamics states that the energy must be conserved when two objects of different temperatures come in contact. If one object gains energy, the other object...

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

Students make ice cream from scratch. They discuss the Food Guide Pyramid and what constitutes healthy and unhealthy food choices. Students experiment states of matter - solids, liquids, and gases. They predict each stage of the ice...

Students identify he phases of matter (solid, liquid, gas), and why they take place. They comprehend what a physical change is and what a chemical change is. Students know the difference between a Mixture and a Solution.

For this matter worksheet, students answer five questions about the law of conservation of mass. They identify substances as solids, liquids, gases or mixtures and they identify given items as matter or energy.

Students list ingredients, utenstils, and steps in basic chocolate chip recipe. They evaluate the correctness of each list using copy of recipe, measure all liquid and dry ingredients, read recipe and follow steps to make cookies.

Students rotate through various hands-on experiment stations to explore the concept and properties of different types of matter. They compare some properties of solids, liquids and gases and describe how matter changes from one state to...

Students convert Celsius to Kelvin temperature. Students conduct three lab experiments, gas law simulations using Internet applets, lectures and demonstrations. The Laws included are Boyle's, Charles, Combined Gas, Ideal Gas, and Gram's...

In this lesson, students investigate the phenomenon of sound! Students compare and contrast how sound travels through solids, liquids, and gases. They explain how length and thickness affect sound. Students know the difference between...

Students study effervescence. In this hands-on science lesson, students apply the scientific method as they complete an activity regarding the presence of bubbles in liquids.

Systematically diluting a full-strength sample of food coloring is meant to help earth scientists understand concentration in parts per million. While they will enjoy the lab exercise, it might be a challenge to help them relate it to...

In this math worksheet, students practice finding the 15 vocabulary terms in the word search puzzle. Word recognition is the focus of the activity and spelling.

Students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. They come up with an explanation for their observations about different amounts of liquids a penny can hold.

Students listen to the book, "Oobleck," by Dr. Suess before experimenting with mystery powders. They determine the proper ratio of powder to liquid to make the Oobleck.
