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...

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 are able to observe chemcial and physical changes while producing a brilliant formation of foam. They are able to experience the use of an indicator in the reaction. Students record information based on their observations.

Students are introduced to a gas chromatography using a discovery-based approach. They are presented with a scenario/industrial application where their job is to verify that the company's mouthwash contains a specific percentage of...

In this substitution and elimination reactions worksheet, students complete 11 reactions by writing the structural formulas for the products. If no reaction occurs, they write N.R. They also write structures of the products for 3...

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...

From types of rocks to types of weathering, learners gain knowledge on minerals, composition of soil, and the effects of weathering on Earth.

Scratch and sniff an introduction to organic chemical reactions. A creative activity has individuals study the esters commonly used in scratch-and-sniff stickers and advertisements. Following the lab procedure, scholars create the...

Three experiments involving pennies help young chemists see the chemical reactions between copper and other elements. The first experiment is rhetorical (it prompts students to leave a bright penny out for a year) but the second two...

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

Why not get creative and use paper clay to create colorful fish sculptures? All the steps needed to complete this activity are included. Your class will sculpt beautiful fish while exploring color, shape, and creative thinking. Use these...

Students watch a slide show about the Philippine Reefs to explore the topic of fish populations. In this reef and fish population lesson, students watch a slide show about fish populations and how the Peace Corps works...

High schoolers become acquainted with the principles of liquid chromatography and construct a liquid chromatography column. Students also investigate the effects of different solvents and solvent concentrations in the separation process.

In this qualitative analysis worksheet, students read about all the different tests that can be done in chemistry to give qualitative results. Tests include flame tests, forming precipitates with sodium hydroxide, using sodium hydroxide...

Students experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry lesson. The lesson was written for an advanced 6th grade class.

Students test for the presence of enzymes in fruit and the specificity of those enzymes, as well as to identify and show the susceptibility of enzymes to certain environmental factors (temperature and pH) originating in the enzyme's...

In this transition metal ions and redox learning exercise, students read about the formation of metal ions through oxidation and reduction.

Students are introduced to the principles of gel electrophoresis. They practice loading gels and pipetting. In this laboratory activity, food color is separated into constituent pigments. The lab can be run with standard electrophoresis...

In this thermometric titration activity, learners investigate the temperature changes when an acid neutralizes an alkali. High schoolers graph their results from the titration and draw the two best-fit lines on their graph. Where the...

For this catalysts worksheet, students use transition metal ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.

Students observe the chemical reaction that occurs when salt is put on ice, and use the energy that is released to make ice cream.

Students study the concept of ice energy. In this ice energy lesson, students observe what happens when salt is sprinkled on a piece of ice before following a recipe to make two types of ice cream. They note the difference in the two...

Young scholars investigate how salt affects the state of ice. In this ice cream making instructional activity, students change the freezing temperature by adding salt and observing the results. Young scholars use experimentation and...

High schoolers covert ethanol to ethanoic acid using a condenser for this oxidation reaction worksheet. They test the smell of the final product, add sodium carbonate, and test the product with indicator paper. They explain their...
