Investigate how Vitamin E is used to prevent cell aging. Young scientists coat the surface of apples and bananas with oil, Vitamin E, and water. They place each in a petri dish and cover them to observe oxidation over time. They answer 8...

Students conduct an oxidation experiment in which they must determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.

In this electrochemistry instructional activity, students determine the half reaction and the standard cell potential. Students identify the species that is the strongest oxidizing agent. This instructional activity has 11 problems to...

It's all about the scale—they're not just wires, they're nanowires! The second lesson of the series builds on the oxidation-reduction experiment in the first lesson. Scholars synthesize a sample of nanowires using electrolysis. As they...

In this electrochemistry worksheet, students are given details as to how to solve strengths of oxidizing and reducing agents, battery chemistry and a summary of cell construction and convention.

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

High schoolers observe the rusting process in the lab. In this chemistry lesson, students rank metals according to their conductivity. They give real world applications of this activity.

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

The 2009 version of the first part of a national chemistry competition is posted for your use with olympiad hopefuls. Test takers deal with 60 multiple choice questions covering an entire year of chemistry curriculum. Use this to...

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

This quiz just looks neat! It has two cell diagrams for biology class members to label. They also describe the function of each organelle. A prokaryotic and eukaryotic cell are displayed for them to compare, and then they fill in the...

If you use this as an outline for your chemistry lecture on metals, your young chemists will absorb a well-rounded overview. This is not a activity per se, but a useful summary of the behavior of metals. Save yourself some planning and...

Chemosynthetic communities of cold seep areas are considered in this lesson. Working in collaborative groups, marine biology or oceanography learners research and prepare a report about oxidation-reduction reactions involved with...

In this metabolism worksheet, students name the two mechanisms for ATP synthesis and give an example of where this occurs for each. Then they explain what happens during the oxidation of glucose and the three steps. Students also...

National Chemistry Olympiad tests are released after their use each year, since they cannot use them again for this event. The result: outstanding comprehensive assessment resources for general chemistry classes! This 2005 version covers...

This four-page worksheet queries young biologists about the process of metabolism in the human body. They describe types of energy, laws of thermodynamics, and chemical reactions related to the processing of energy. Plenty of space is...

Learners observe and record the corrosive nature of oxidation-reduction reactions, and determine the electro-chemical series of selected metals.

For this redox worksheet, students determine the oxidation numbers of each element for the given chemical formulas. Students write out the reactions for each example given. Students identify what part of the chemical equation is...

For this electrolytic cell worksheet, students read about car batteries and how they produce electricity for cars to run. They answer six questions about electrolytic cells and oxidation-reduction reactions.

Explore the chemical components of water through an electrolysis reaction. Scholars use a battery to divide various water solutions into different gases. As they collect the gases, they measure the volume and make a comparison to the...

Explore how electricity splits water molecules into hydrogen and oxygen. Learners begin by calculating the voltage necessary to separate the water. They then perform the experiment and measure the ratio of hydrogen and oxygen bubbles.

In this chemical reactions learning exercise, students are given directions about three types of reactions and how to write balanced equations for each. They then are given ten practice problems to complete using the information given.
