Here is a cut and paste activity worksheet designed for older students. They fill in the blank with information about the composition of DNA, then create a DNA strand with its complimentary nucleotide chain.

For this RNA worksheet, students compare and contrast RNA from DNA. Students complete 1 multiple choice and 8 true or false questions.

Tenth graders complete a vocabulary assignment based on terms in the unit. They complete appropriate worksheets as each section of the unit is completed. They participate in classroom discussions. They construct a model of a DNA molecule.

In this environmental studies worksheet, students create a data table to discover how much water each person uses on a daily basis and what it is used for. They complete a post activity to make and test solutions for pollution using a...

Ninth graders complete an experiment to determine the pH values of a variety of common household substances. They use red cabbage to find the indicator colors of the pH range. They complete a data table that includes a prediction and...

What acids are and how they are named are the main topics approached in this slide show.  Explore the definitions and behavior of acids, along with directions for naming and writing reactions.  The last slide has some practice...

In this chemistry activity, students write the net ionic equations for any precipitation reactions that occur on mixing aqueous solutions for each of the substances listed. Then they write the net ionic equations for the acid/base...

Students think of one way to detect photosynthesis in plants besides those ways shown in class. They identify the reaction that occurs during photosynthesis. Students define the difference between an acid and a base. They identify acidic...

You are what you eat, as they say! Are you more starch or more protein? Young scholars use their knowledge of each component to test different foods for their content. Using multiple indicators, individuals describe the protein and...

Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...

In this acids and bases worksheet, students apply the Bronsted-Lowry theory of acids and bases to write the products for the given acid-base reactions. This worksheet has 7 problems to solve.

Students study descriptions of indicators and the way they are used to identify acids and bases. They use this information to determine if unknown solutions are acids or bases.

Eighth graders experiment what happens when acids and bases are mixed together. In this acids and bases experimental lesson, 8th graders decide which of three solutions of unknown pH will neutralize a fourth solution of unknown pH.
