In this grade 5 science test worksheet, 5th graders complete a 30 question multiple choice quiz covering a variety of grade 5 concepts. 

Students research chemical formulas and balance chemical equations.  In this chemical equations lesson students complete a class activity on chemical equations and answer questions.

Students construct flow diagrams of the carbon and nitrogen cycle processes. They identify sequences in each cycle that are affected by human impact and present their research to the class.

Students use research to see how eight pairs of triplets are equivalent to part of a gene and control a part of heredity. They also understand how red blood corpuscles manufacture normal hemoglobin.

In this elements worksheet, high schoolers review the most common elements found in living things. Students color in two pictures with the percentages of the elements found in that living thing.

Young scholars imagine themselves working as research scientists completing the end-steps of a molecular research project and interpreting the data. They compare the gene sequences of normal and abnormal mice and evaluate the protein...

In this chemistry 302 worksheet, students determine if the reaction is a battery or electrolytic. Kids balance the reaction and then indicate which species is receiving the electrons. Students fill in a table for a battery made from the...

Pupils observe a demonstration that shows that the indicator, phenolphthalein, is a chemical that displays different colors depending on either the acidity or the basicity of the environment. They use the substance to reveal secret...

Young scholars apply the scientific method and safety rules to aquatic pH. They test unknown solutions for pH levels.

Students participate in a hands-on activity to investigate how water is recycled in a small environment, and determine how water is cycled on earth.

Pupils explore the tissues of the bone. They discuss bone composition and physiology. Students perform experiments to compare and contrast the decalcifying properties of several liquids.

Learners construct a volcano using baking soda and vinegar. In this earth science lesson, students explain the reaction that takes place when these two chemicals combine together.

Students compare/contrast the DNA sequence data of the rat GULO gene to the inactive human GULO gene. They translate and align the sequences, and propose a scenario to explain the occurrence of an inactive DNA sequence to that of an...

Pupils make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other chemicals.

Students experiment using the basic principles of gel filtration. They use the gel filtration technique for testing for the presence of specific substances. Students discover that starch is a larger molecule than glucose.

Students achieve a week long activity in preparation for a group presentation on a human genetic condition

Seventh graders explore how exercise affects carbon dioxide levels in exhaled air.

Pupils investigate major pigments which occur naturally in fruits and vegetables, and to use them to dye a number of items. They study the effects of pH on anthocyanin on pigments.

Students use the internet to research air bags in cars and trucks. In groups, they discover air bags history and the safety issues surrounding them. They create their own design of a new air bag and test it using a raw egg in...

Fourth graders identify the characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and separate or sort items using these properties. Students explain...

Students consider the role of industry on the American landscape from a variety of perspectives. They investigate a simulated case study. They investigate a chemical spill catastrophe. Students write an informative pamphlet to assist...

Students explore and explain how mutations in the DNA sequence of a gene may be silent or result in phenotypic change in an organism and in its offspring. They analyze how evolution and biodiversity are the result of genetic changes that...

In this bacteria worksheet, students read several elements of bacterium cells, their diet, types, locations, reproduction, resting stages, effects of, and classification. Students also study a cross-section of bacterium cells.

Listen and learn about Arrhenius acid-base reactions while exploring mixtures, solutions, and their reactions. Examine the photos of the examples discussed in this website and discover how arrhenius acid-base reactions occur.
