In this equilibria worksheet, students are given detailed information about LeChatelier's principle and how to solve equilibrium problems. They then calculate concentrations of compounds in solutions.

In this polymer worksheet, students make two types of cross linked polymers and they test their physical properties. These include their response to agitation, stretchability, viscosity, and resilience.

Students use short-chain polymers and borate ions to produce cross-linked polymers in the lab. In this cross-linked polymer lesson plan, students produce polyvinyl acetate slime and polyvinyl alcohol slime and test their physical...

Students investigate the effects of four different shaped wands and geometric shapes in a bubble solution. In this bubbleology lesson, the students build water and soap molecules. Students work in cooperative groups and conduct...

Pupils investigate the mixtures of solutions. They utilize cups filled with bases and acids. Students test and determine the pH of each cup. The multiple cups are compared to each other in order to chart acids and bases according to pH...

Students make ice cream as a result of viewing changes of states of matter. In this matter lesson plan, students learn how heating and cooling can effect a state of matter to change.

Students observe an experiment of freezing point depression using club soda. Through observation, they note that the carbon dioxide molecules disrupt the capacity of the water molecules to solidify. Precautions must be taken to assure...

Students describe pH and the importance of it in the natural world.  In this Biology lesson students compare the pH of different mixtures.

Students perform tests on different chemicals to determine their chemical properties. In this forensic science lesson, students identify an unknown sample using its physical and chemical properties. They solve a fictional crime using...

Students isolate DNA from kiwi cells, spool DNA from a kiwi, describe role of the DNA and genes, and explain how knowledge of DNA and genes can be used in genetically modifying foods.

In this chemistry of life worksheet, students will review key terms of plant cell structure and chemistry by reading 13 clues to complete the puzzle. Word bank is included.

What constitutes a good soap bubble? In the second installment of a nine-part series, scholars apply their understanding of surface tension to soap bubbles. They experiment to determine the best solutions to use for the...

Third graders use the scientific method as they separate the colors used in ink. For this chromatography lesson, the teacher introduces students to how chromatography is used in several careers, then students perform an experiment to...

Students analyze and classify substances.  In this classifying matter instructional activity, students look at various substances and identify them as heterogeneous or homogeneous mixtures, pure substances, or solutions. ...

Students participate in a variety of activities that involve bubbles. In this bubbles lesson plan, students make bubbles out of a soap solution, make bubble domes, make bubbles with their hands, and more.

Students predict, observe and draw conclusions while working on an experiment with "slime." Students accurately record observations and draw conclusions about the experiment.

Young scholars mix two different solutions to become more familiar with molecules and polymers. In this chemistry lesson, students decide whether or not the reaction between two solutions is chemical or physical. Young scholars then...

Students participate in an experiment in which they culture bacteria in a lab setting. They record their observations and analyze the data. They answer comprehension questions to end the lesson.

Weighted averages can be tricky to explain! However, this study guide makes it easy for teachers by including definitions, explanations, and breaking down problems into three steps. Includes mixture problems and uniform motion problems.

Who's going to get slimed? Your entire class! Scholars create slime using Borax, water, and white glue. Some food coloring can give the slime a bit of color.

Let the lab be a catalyst to learn about enzymes. Scholars create alginate beads filled with yeast. As part of an investigation into enzymes, they see how these beads provide a catalyst to the reaction of glucose into ethanol.

Students explore conductivity and productivity in aquatic systems.

Students determine what characteristics are useful in classifying items.  In this sorting organisms instructional activity students create and explain a classification scheme using familiar organisms. 

Learners explore acids, bases, and indicators. They observe the various colors of an acid-base indicator solution and the neutralization of an acidic solution by an antacid.
