Students examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.

Young scholars learn how science affects foods. In this chemical reactions lesson, students make two kinds of ice cream. They evaluate the different changes based on the ingredients.

Pupils use one of four absorbent products to separate as much of the oil and water mixture they are able to do. The purpose of this task is for students to collect and analyze data for the purpose of determining which absorbent is best,...

Second graders discover the process of osmosis. For this science lesson plan, 2nd graders learn how different kinds of solutions move through selectively permeable membranes, understand the role of osmosis in the movement of molecules,...

Students make a polymer but they won't be getting instructions. They'll get materials and they must figure it out on their own and report the actual steps needed back to the teacher.

Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...

Students explore biology by participating in a fun science experiment. In this DNA instructional activity, students discuss what DNA is and where it comes from. Students utilize two bananas, a blender and a microscope to view the DNA of...

Students create coal flowers. In this mining lesson plan, students discuss the importance of coal during the 1800s and use ingredients to make coal flowers. Students determine the effect temperature has on crystal formation.

Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...

In this chemistry competencies worksheet, students calculate rate law, balance equations, determine pH of solutions, give the oxidation number for atoms, and write in formulas. This worksheet has 4 fill in the blank questions and 20...

In this equilibrium instructional activity, students predict the concentrations of solutions at equilibrium and apply Le Chatelier's principle to systems at equilibrium. This instructional activity has 15 multiple choice questions.

In this equilibrium worksheet, students solve eight problems including determining the effects of changes to a system as it related to Le Chatelier Principle, calculating equilibrium constants and finding boiling points of solutions.

Students participate in a demonstration that illustrates the relative amounts of salt in various bodies of water including the Dead Sea, Sallt Lake, Ocean water and distilled water. They taste and compare various mixtures.

This is an advanced rates of reactions worksheet. Students will be determining reaction times, molarities, and reactions rates for different reactions.

Students explore composting. In this composting lesson, students use compound microscopes to observe the microbial communities in compost. Observations and documentation of changes will occur over the course of several weeks.

Students make a crystal snowflake decoration out of string, pipe cleaners, food coloring, boiling water, and more. In this snowflake lesson plan, students let it dry over night and see crystals in the morning.

Middle schoolers examine how one of the ways the mining companies extract coal is through the flotation method where air bubbles float coal particles to the top of a solution. The coal is scooped off and separated. They participate in...

Pupils are introduced to the principles of gel electrophoresis and also provides an opportunity for students to practice loading gels and prpetting. In this laboratory activity, food color is used to separate into constituent pigments.

Students conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...

Middle schoolers discover how paint is made, then create their own paint which they will use to create a picture. After witnessing the processes of emulsion and suspension, students work in groups to create their own paint, and then...

Students make their own pH indicator from red cabbage. Red cabbage contains a chemical that turns from its natural deep purple color to red in acids and blue in bases. Students boil the cabbage to get the pH indicator.

Students calculate the concentration of different solutions. In this chemistry lesson, students explain what a solution is. They explain ways to change the concentration of a solution.

Sixth graders experiment with the froth flotation process to extract metallic ore by using basic chemicals and equipment in the science classroom.

For this science worksheet, students find the terms that are related to the concept of the ocean salt and sand. The answers are found by clicking the link at the bottom of the page.
