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

Students discuss the major changes that have taken place in the Hudson Valley over the past 400 years. They use aerial photos to describe major trends in Dutchess County. Students view a PowerPoint presentation. They work in small groups...

A three-page quiz assessing budding biologists' understanding of classification. Middle-level learners may need a little additional time on this, but should be able to handle the concepts with ease.

Fifth graders investigate evidence for changes in matter that occur during a chemical reaction.

For this compounds worksheet, students review the rules for naming compounds. Students apply these rules by writing the chemical name or formula for the 50 compounds given.

For this chemical reactions worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with 34 clues.

Students 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...

Students identify the signs that a chemical reaction took place. In this chemistry activity, students role play the movement of different molecules of matter. They classify matter according to their properties.

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.

In this chemistry worksheet, students examine the concept of thermodynamic equilibrium constants with intense detail. The application of the knowledge is practiced with problem solving.

Students explore chemical solutions. In this chemistry lesson plan, students investigate the relationship between three related experiments about solutions. Students determine variables that affect the chemical concentration of each...

Eleventh graders work together to complete a simulation on infectious diseases. They determine which concepts affect a disease more. They complete discussion questions as well.

Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

High schoolers define what a redox reaction is. In this chemistry lesson, students electroplate some wires in the lab. They research the application of electroplating in the real world.

Pupils 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 write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.

Students calculate the concentration of different solutions. In this chemistry activity, students explain what a solution is. They explain ways to change the concentration of a solution.

This site presents everything you need to know about acids and bases and more! Gives a nice description on what acids and bases are, properties of both, strong and weak acids and bases, an overview of pH, and much more.

An explanation of historical ideas that lead to the current day concepts of acids and bases. The Concept of pH is briefly introduced.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students investigate the different chemical and physical properties of acids and bases.

Listen and learn as you discover definitions for acid, base, and acid-base reaction. View example formulas of Arrhenius and Bronsted-Lowry acid and bases.
