Eighth graders identify the three main types of chemical bonds. In this chemistry lesson, 8th graders draw Lewis dot diagrams of elements and determine the bond formed. They create a model water molecule.

Here is a laboratory exercise in which chemistry masters conduct an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. This activity is aimed at...

It is best to avoid jokes about noble gases; they get no reaction. Scholars match the noble gases to their symbols and uses. Then they solve three gridlock puzzles reviewing the material while applying some simple logic.

In this descriptive investigation worksheet, 6th graders conduct an investigation to determine if heat energy affects the brightness of a light stick. The students will form a prediction, collect data and answer 3 conclusion questions.

Eighth graders analyze physical change in mass. In this chemistry lesson, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with elements,...

Students experiment with acids and bases. For this elementary level chemistry lesson, students perform activities for testing acids and bases. They use universal indicator paper to determine which substances are acidic and which are...

Students study the chemistry of ammonium nitrate and consider the advantages and disadvantages of this compound. They compare different fertilizers and calculate the molar mass and percent nitrogen in the different fertilizers.

This lab activity is geared toward experienced chemistry learners, in particular, those who are familiar with organic chemistry. They will create a synthetic elastomer  and then make observations and measurements of its different...

Eighth graders give some examples of chemical reactions they see everyday. In this chemistry instructional activity, 8th graders investigate how much water soil can hold. They collect data and compare results with others.

Students write and balance five chemcial equations which have been observed throughout the process of completing the experiment. They use vacuum filtration to recover suspeneded particals from a colloidal suspension. Students correctly...

Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

More extensive than just a general overview of digestion and reactions, this slide show gives information about all areas of enzyme function.  Topics like the chemistry behind efficiency of enzymes, factors that affect speed of...

Students investigate that chemicals may affect different people in different ways. They also realize that their perceptions of dangerous materials may not be realistic and that the news media may not provide all the information needed to...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Lesson 19 in the series of 36 analyzes the element hydrogen and the s-block elements. Through readings, answering questions, and discussion, learners write about and explain their occurrence, physical and chemical properties, and...

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

This series opens with diagrams of experimental setups. A data table is displayed and questions are asked, indicating that the intent is for lab groups to perform the depicted experiments. At slide twelve, a coherent lesson about the...

Thirty-seven slides thoroughly shed light upon the four classes of matter: elements, compounds, mixtures, and solutions. Also covered are chemical symbols, molecules, and chemical equations. The colors and fonts chosen for the...

You didn't know you'd find moles in chemistry class! Through the introduction of moles and molar volume at STP, classes see how to calculate moles using a given chemical equation. The presentation includes a short review of ions in...

Young scholars explore the science of toxicology and the relationship between a toxic reaction (response) and amount of substance (dose). They observe two demonstrations illustrating the concept of dose-response.

Chemistry and earth science meet in a lesson plan on carbon dioxide emissions. After reading about atmospheric problems caused by using fossil fuels, science stars balance equations for the burning of different alkanes. They compute the...

Students develop abilities necessary to do scientific inquiry. They develop an understanding of chemical reactions, structures and properties of matter. They develop decision-making skills in natural and human-induced hazards.

In this chemistry worksheet, students find the words that are related to atoms and molecules. The answers are found by clicking the link at the bottom of the page.

Students explain the process of polymerization. In this chemistry lesson, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.
