Students watch and learn the different levels of "viscosity" in liquids to explain molten lava after viewing a video of a Hawaiian volcano.

Young scholars examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.

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

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...

In this online interactive photosynthesis worksheet, students respond to 9 multiple choice and fill in the blank questions regarding the information included in the provided paragraphs.

Students make ice cream as a result of viewing changes of states of matter. In this matter lesson plan, students learn how heating and cooling can effect a state of matter to change.

Students explain monomer/polymer chemistry of starches and sugars.

Students write a balanced chemical reaction. They articulate how burning fossil fuels increase the carbon dioxide levels in the atmosphere. Students incorporate all the environmental risks involved as well.

In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...

In this solids worksheet, students review terms associated with solid matter including, freezing and melting point, viscosity, and Brownian motion. This worksheet has 1 short answer and 14 matching questions.

Students study ice worms  and describe how they interact with other species.  In this methane hydrate instructional activity students study ice worms and hydrate shrimp to learn their behavior and can participate in an optional...

in this working with tenses worksheet, students identify time expressions in sentences. Students then determine the tense of each of the verb phrases and create new sentences.

Students study chloroplasts, their structure and evolution.  In this photosynthesis lesson plan students experiment with polarized light and the production of chlorophyll.
