In this solubility activity, students test a variety of polar and non polar substances to determine which ones will dissolve in vegetable oil and which ones will dissolve in water. Students collect data and answer 2 questions about their...

Physics lab groups finagle with laser lights to determine the critical angle of refraction for both water and Lucite. Because there are no detailed steps or an answer key for this enlightening exercise, an inexperienced physics...

In this crystals activity, learners complete a graphic organizer by filling in the characteristics of the different crystal types including melting/boiling point and electrical conductivity.

Students examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.

Students, through video segments, explore what types of animals live in the Arctic and Antarctica. They also clear up any misconceptions they have about penguins or polar bears.

Students experiment with the decomposition rate of garbage. They discover that environments are fragile and need to be protected and resources are not always used wisely. They then think about their own environment and then about the...

For this chemistry of life worksheet, students will review key terms of plant cell structure and chemistry by reading 13 clues to complete the puzzle. Word bank is included.

In this solutions worksheet, students compare situations that increase or decrease the solubility of a solute. Students describe how surface area, stirring, and temperature can increase the rate of dissolving a solute. This worksheet has...

Pupils apply problem solving techniques to answer a question. After reading a passage, they compare and contrast three species of whale in a quantitative fashion.

Fifth graders research life in Alaska and compare life there to their lives in this instructional activity. They read "Julie of the Wolves." They research through the novel and other reference books facts about the Alaskan climate and...

Students examine maps of different projections, mathematically calculate distortions, and note the advantages and disadvantages of each map. They study the different maps and transfer the map to graph paper.

In this organic molecules worksheet, students solve nine problems involving reactions of organic molecules. They must draw and label reactions, explain the processes of the reactions and predict products of reactions
