Students recognize whether a solution is an acid or a base. In this acids and bases lesson plan, students use chemicals and identify if those chemicals are acids or bases. From the conclusion, students will be able to identify if the...

Sixth graders explore chemical and physical changes. In this lesson about chemical changes, 6th graders observe various items and changes that occur at certain times. Students determine what change took place and observe the change....

For this elements and compounds worksheet, high schoolers review the physical properties of different compounds and elements using websites for information. This worksheet has 1 graphic organizer and 1 short answer question.

In this rate, ratio, and proportion worksheet, 7th graders solve ten multiple-choice problems.  The solutions are provided by clicking on the "show answers" on the bottom of the page.

Students explore seafloor sediment. In this ocean environment instructional activity, students describe the characteristics of different types of seafloor sediment and oozes. They compare and discuss locations of sediments and oozes by...

Students examine amino acids and discuss the properties of side chains.  In this proteins instructional activity students demonstrate the foldings of peptides.

Students explore renewable energy by analyzing a diagram. In this fossil fuel lesson, students view a chart explaining the different energy consumption from automobiles and how they impact our environment. Students analyze a point based...

In this chemistry, students draw the Lewis structures of 20 covalent compounds. They demonstrate how the lone pairs are distributed in the molecule.

Learners list reasons why water is important and investigate and graph the freezing points of different solutions.

Students investigate acids, bases, and pH, and related this knowledge to the problem of acid deposition.

Young scholars identify producers and consumers from marine ecosystems and describe the balance among them in the environments. After constructing a food chain from a marine ecosystem, they examine human activities that can upset the...

Students investigate the affect of soap and water temperature on surface tension.

Students explore the nature and composition of a comet. They research comet facts, legends, and myths. They identify different types of comets and describe what happens to a comet as it travels closer to the Sun.

Students cuminate their study of molecular structure and bonding with this activity.

Students investigate how efficient different substances are at melting snow. Students collect and analysis data.

Tenth graders observe enzyme activity. They discuss the relationship between drug use and enzyme activity.

Learners research various forms of alternative energy sources and examine the pros and cons of each type. They discuss American oil dependence and the Bush administration's policies regarding this issue.

Students view a video on DNA. They discuss mitosis, meiosis and fertilization. They use strips of paper to simulate fertilization and analyze the genotype and phenotype of the combined chromosomes.

Students discover that all paper is recycled the same way, and that some paper requires complex chemical treatments before it can be made into usable recycled paper. They see that we must choose what kinds of paper minimize environmental...

Learners discuss how much fiber and water a person needs each day. They use beans soaked in water to show the benefits of water to the human body. They also learn the health benefits to eating healthy.

Students examine the effects of specific enzymes on samples of liver tissue, muscle tissue (chicken), apples, and potatoes.

Students explore the concept of molecular modeling and differentiate between saturated and unsaturated compounds. In small groups, they identify molecular formulas, complete a chart comparing alkanes, alkenes, and alkynes, and construct...

Students define energy and identify the different types that exist. They identify places they see, hear or feel energy. They understand the role of engineering in finding and testing sources of energy for the production of electricity.

Students will demonstrate knowledge of the structure of DNA by constructing simple models of DNA with materials given to them in class. They will also discover that some female scientists such as Rosalind Franklin have not been given...
