Young scholars define and identify endothermic/exothermic reactions. Using a series of experiments, they construct and interpret potential energy diagrams for their reactions.

Students are able to prepare and use pH indicators in paper form. They find out the color of the indicator paper plus test solution may change with time. Students use red cabbage to use for the indicator.

Students identify the difference between some physical and chemical properties and compare some physical and chemical changes. They design an experiment to distinguish between a physical or a chemical property of their choice.

Students explain the implications of particle theory of The Law of Conservation of Matter for problems of pollution and waste disposal. They describe, in terms of atoms and molecules, what happens to materials when they are dissolved or...

Pupils weigh out the proper amount of silver nitrate and prepare the silver nitrate solution. They observe what occurs when pure copper is added to silver nitrate solution. Pupils determine whether the change in the appearance of copper...

In this periodic table I quiz, students select the best answer to the given questions. Students apply their knowledge of the periodic table and the arrangement to correctly answer the questions presented.

Students explore respiration in a lake ecosystem by experiment and research.

Students analyze chemistry by conducting an in-class experiment. In this slime lesson, students discuss what slime is and what form of matter it qualifies as. Students utilize borax, glue, water, cups, food coloring and plastic bags to...

Pupils investigate the absorbency of certain diapers. In this inquiry instructional activity, students examine how much water the crystals absorb. They collect data and share their results in class.

In this irregular verbs worksheet, students write the correct form of the irregular verb in simple past tense. Students complete 12 sentences. Students then make their own sentences using irregular verbs in simple past tense.

Young scholars demonstrate the scientific method by conducting an ice cube melting experiment. They make predictions and observations, and conclude what factors make ice melt more slowly or quickly than normal.

Focus on oxidation-reduction reactions with a review worksheet. Junior chemists answer short-answer questions before they write balanced half-reaction and full-reaction equations.

Calories are not tiny creatures that sew your clothes tighter every night, but what are they? A science lesson, presented at multiple levels, has learners experiment with heat, heat transfer, and graph the function over time....

For this solubility worksheet, students calculate the final concentrations of the ions involved in a chemical mixture. Students calculate the solubility of different compounds. This worksheet has 13 problems to solve.

Fifth graders discuss the differences between chemical and physical changes. In groups, they complete experiments and discover how a physical chnage can be reversed. To end the lesson plan, they review the steps of the water cycle and...

In this acids and bases instructional activity, 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...
