A great review of the structure and function of carbon-based molecules important to life, especially with relevance to humans. The chemistry behind the combination of polymers and the breakdown of bonds is covered. Valuable content...

In this acids and bases worksheet, students read about the differences between acids and bases and then complete a table comparing the characteristics of both. Then students determine if the given statements describe an acid, base, or...

Students explore acids and bases and the process of neutralization.T hey practice volume measurements and observe the neutralization of an acid directly through bubble formation and indirectly through indicator color changes.

In this chemistry worksheet, students solve twenty five multiple choice problems about a variety of chemistry topics. Students answer questions about equilibrium, solubility, reaction rates, titrations, and entropy.

You matter—unless you multiply yourself by the speed of light squared, then you energy! Scholars learn about matter, energy, the elements and so much more using an informative presentation. Completing the included worksheet creates a...

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

A half-page chart compares the properties of metals and nonmetals. Properties include appearance, melting and boiling point, density, strength, malleability, ductility, heat and electrical conductivity, and the nature of their oxides....

Explore the makeup of the earth's atmosphere. Using the set of specific experiments, pupils examine the main elements and compounds present in the atmosphere. Their study extends to investigate the effects of atmospheric...

Young scholars describe characteristics and common uses of acids and bases. They describe the role of natural indicators in the chemistry of acids and bases after testing and making observations on a variety of plant extracts. Students...

Young scholars list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their...

Students investigate the protein cytochrome c in an attempt to use its genetic chemistry to study possible evolutionary relationships between organisms. The instructional activity integrates technology with the use computers to perform...

Students test the pH of soil samples they collected from the field trip. In this chemistry instructional activity, students differentiate acids and bases. They write a lab report about the experiment.

Students study the differences between an acid and a base.  In this pH lesson students view a demonstration then test chemicals in groups.

Eighth graders experiment and study about acids and bases by becoming involved in direct hands-on learning experiences and then relate those experiences to their own lives. They experience the Ohio River and what can be done to help...

Although their name makes them sound dangerous or toxic, carboxylic acids are found throughout nature in things such as citric acid, vinegar, and even in your DNA. Through detailed readings, discussions, and answering questions...

In this science worksheet, students examine the safety labels that are displayed in the laboratory and then are expected to complete the homework questions.

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

After viewing this presentation, students create a complete set of notes to support their learning of DNA replication. Each slide has information on a step in DNA synthesis process. The slides focus primarily on the processes rather than...

In this acid and base instructional activity, students review the characteristics of acids and bases, how to calculate pH of a solution, and define a buffered solution. This instructional activity has 16 multiple choice questions and 3...

In this activity, learners review the definitions of acids, bases, and salts. They also describe the differences between acids and alkalis and define neutralization. This activity has two short answers and one problem to solve.

Sixth graders describe the physical and chemical properties of acids. In this chemistry lesson, 6th graders test the acidity of different solutions. They identify acids and bases using the pH scale.

In this acid base learning exercise, students calculate the concentration of solutions as products of acid and base reactions. This learning exercise has 9 problems to solve.

For this biology worksheet, students identify and describe the three types of RNA, messenger, transfer, and ribosomal RNA. Then they write the key features of molecules of RNA for each form.

Chemistry stars calculate ion concentrations, pOH, or pH in different solutions. For questions in the latter half of the learning exercise, they also have to explain why a solution is acidic, basic, or neutral and solve for molarity of a...
