Students titrate a sample of fatty acids with standardized sodium hydroxide solution. From the amount of base needed for neutralization and the mass of sample used for titration, the apparent average molar mass of the sample is...

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.

In this percentage worksheet, students calculate percentages given various types of problems. They calculate percent of compounds in a solution, they calculate mass of compounds given percentages of solutions, and they percentages of...

Tidy slides and lecture notes for each are included in this presentation on alloys. Instruction begins with the molecular arrangement of a pure element, gold, and progresses to a few example alloys: brass, steel, and nitinol. This...

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.

Here is a good lesson which aptly describes how to do the classic "Oobleck" lab with your young scientists. Unfortunately, the "Oobleck Investigation Sheet" in the plan doesn't open. However, this is a very clear description about how to...

Don't you wish you had the time to type up a study guide for your chemistry class? With this resource, there is no need! A chart comparing the properties of metals and non-metals tops the handout, followed by notes on the reactivity...

Surface area certainly surfaces as a variable for chemical reaction rates. Scholars perform an experiment to discover how the size of catalysts affect the rate of a chemical reaction. They record their results in tables and graphs to...

Investigate the amazing ability of plants to filter contaminants from water with this series of in-class demonstrations. After placing six small, potted plants in plastic cups, different solutions and mixtures are poured into them that...

Puzzling over what geometry instructional activity to teach next? Look no further. This simple activity teaches young mathematicians how shapes can be decomposed into smaller figures, and how smaller figures can be assembled into larger...

Is the hamburger in that fast food commercial real? Interest your class in this reading assignment by playing a short fast food commercial using YouTube. Then, give your class this reading passage, and have them complete the multiple...

There is more than one way to answer a question; especially when you have fractions in measurement. Here are three questions with real-world situations in which 5th graders are asked to provide answers in three ways: a larger unit of...

Fourth graders explore the many uses of corn-based products and the importance of water resources. They consider how biodegradable products help to keep water clean. They perform experiments to observe how corn pellets dissolve while...

Students make their own recipe. In this art lesson, students mix dry ingredients with a little water and see the changes made.

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.

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.

In this science worksheet, students apply science basic knowledge of chemistry to the puzzles that are listed for the four parts of the sheet while focusing upon the identification of a metalloid.

Learners 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.

Students identify parts of plant and animal cells and describe the functions of each part. They distinguish between plant and animal cells. After a lecture/demo, students perform experiments which help them construct models of plant and...

Students conduct an experiment in which they systematically separate cations from a mixture of substances. They use the following types of reactions to do so: precipitation, acids and bases, oxidation and reduction. They compare a...

Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...

In this solutions worksheet, students read about how people first learned to use metals and to combine metals to form alloys. Students write an essay telling the story of how ancient people first learned to cause physical changes in metal.

Eighth graders determine which of two solutions is more acidic by adding each to a given base. Students have to apply this analysis process to a problem scenario involving an alien creature.

Learners answer questions about how microorganisms can affect our food supply and how they can be controlled. The first set of inquiry activities are directed by the teacher. Subsequent activities are based on students generating their...
