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...

Students research number values by participating in a candy exercise. In this math function instructional activity, students utilize baking ingredients to create cookies and multiply how many M&M's will go into the batch if you want...

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...

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...

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.

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...

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

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

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

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.

Ninth graders identify the characteristics of fish.

Students practice calculating density and examine examples of the physical characteristics of soil. They solve a "crime" based on the evidence and laboratory investigations.

Tenth graders explore DNA using online tutorial. They perform their own DNA extraction from a clove of garlic and identify the key components of DNA.

Learners read about a cholera outbreak in the 1840's. They read maps, predict how cholera moved throughout the country and participate in a lab activity that demonstrates how disease is spread. They compare cholera through time.

Sixth graders create a type of notebook or journal using colored copy paper on which to take notes. They complete research on a certain disease and report on it and then design their own disease causing bacteria or virus. Finally, 6th...

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

Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Young scholars 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...
