Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

Seventh graders observe and test for the presence of carbon dioxide gas. They compare concentrations of carbon dioxide gas and conclude high concentrations of carbon dioxide gas are unhealthy for human beings.

Students experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry instructional activity. The instructional activity was written for an advanced 6th grade...

Second graders work with gases to determine what the effects of temperature are on volume and air pressure by working with balloons. Also, they experiment with vinegar and baking soda. They predict the outcomes of these experiments, and...

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Middle school environmentalists record the pH of four different liquids, including two aerosol cleaning products. They liken the products to acid rain and speculate in writing which might affect the human respiratory system. Although...

Learners identify substances and activities within a household that contribute to water pollution and identify safe cleaning alternatives for commercial cleaning products.

Students investigate landforms by holding a class experiment. In this topography lesson, students define the word "karst" and discover why sinkholes are created on the surface of the Earth by completing worksheets. Students create a...

Students list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their understanding.

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...

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