These 37 slides start with definitions of six types of functional groups, their molecular structure, and multiple examples or each. During the rest of the presentation, organic chemistry learners are given an opportunity to practice...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

In this chemistry olympiad laboratory learning exercise, learners design and carry out two experiments. They design one experiment to test for the percent mass of a substance in a solution and they design another experiment to identify...

In a hypothetical scenario, food chemists use titration to concoct a brine solution for producing the crunchiest pickles. They also analyze store-bought pickle juices. In addition to reinforcing titration techniques, the instructional...

The University of the State of New York has designed a series of exams for high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety of styles,...

In this acid and base worksheet, students calculate the concentration and pH of solutions. This worksheet has 7 problems to solve.

Learners explore pH levels of different substances. In this lesson about pH, students work together in three to four groups to test substances. moving between three different stations performing tests on the substances to determine...

In this RNA instructional activity, students determine the function of mRNA and tRNA and create an mRNA strand from a given DNA strand. Students describe and compare the 3 types of RNA. This instructional activity has 1 drawing, 2 fill...

Junior biologists compare the amino acid sequences from fragments of five different globin molecules. They count the letter differences between each species pair. They construct a graphic representation of the evolutionary relationships...

Students study acidic and alkaline balance. In this acid and pH levels lesson, students read information about pH, the formation of acid rain and its impact on environments. Students then complete an experiment to learn about the...

Determine the number of possible genetic codes. Class members are challenged to determine the number of possibilities of a genetic code that is 20 bases long. They continue to explore the average lengths of broken RNA molecules.

Though there are technically only 13 questions on this exam, they take up six pages and make a thorough assessment of organic chemistry principles. There are plenty of diagrams to label or complete. Emission spectra are displayed for...

Amphoteric compounds act as both an acid and a base. Scholars apply their knowledge of the four oxide types while completing four puzzles. They match a sample of each type of oxide with the corresponding reaction.

In chemistry, organic means something contains a carbon base. A helpful presentation starts by defining macromolecules as large organic carbon molecules. Scholars answer questions about each topic on the associated worksheet. It covers...

How do mice have so much fur color variation over generations? Scholars illustrate protein structures based on amino acid sequences. Then, they analyze the signaling pathway in different-colored mice populations. This allows them to...

Finally, a chance for the class to play with their food! Allow pupils to simulate stomach acid with common foods, and introduce specific macromolecules into the mixture to explore characteristics of carbohydrates, lipids,...

What happened when the chemistry teacher told a bad joke? There was no reaction! A creative take on the traditional reaction types lesson invites learners to draw their own conclusions about how compounds and elements combine. Groups...

Whether you are teaching environmental science in junior high or studying recycling in kindergarten, there is something for all in this set of lessons designed for environmental education. The 110-page packet comes with tips for...

In this acids, bases and salts worksheet, students solve five problems in order to determine the molarity of solutions or the volume of substances to be added to make molar solutions. They also solve five dilution problems about acids.

Middle schoolers explore acids, bases, and indicators. They use turmeric solution, phenolphthalein, and goldenrod paper to determine the acidity and basicity of a variety of common household substances. A worksheet is included to record...

For this biology worksheet, students identify and label the diagram shown by stating what each part of the diagram represents on the line. Then they use the DNA strand as the original strand and complete the data table. Students also...

In this equilibrium instructional activity, students solve nine problems related to acids, bases, buffers, ionization and calculations of pH.

Students investigate acids, bases,and pH. They test the acidity and basicity of various household items using litmus paper. Using their results, they rank the substances according to pH and identify the contributing chemical on the label.

In this volumetric analysis instructional activity, learners experimented with a known amount of hydrochloric acid to determine the relative molecular mass of an unknown group 1 carbonate. Students use volumetric analysis to determine...
