Fifth graders construct a voltaic battery. They change chemical energy into electrical energy by inserting copper wire into a lemon. They discover the tingle of the wire on their tongue is due to the movement of electrons.

Students investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the balloon...

Students state the physical, chemical or biological processes associated with these environments: Pelagic ocean zone, California coat Cave, Indiana Barrier island beach, North Carolina Sand dune, Dunes National Park, Colorado Wetland and...

Students consider what happens to herbicides or insecticides that are used in agricultural practices, especially herbicides that are used to control noxious weeds. They become acquaint with a chemical assessment method known as...

Students explore light, and how it travels in straight path, recognize that light-sensitive chemical processes can be used to create images using light as catalyst, discover that light can be refracted by convex lens to focus camera,...

Students explain chemical, cultural and biological weed control methods. They design and conduct an experiment to simulate a weed control method and explore various ways to prevent weed dispersal.

Give this summary of 16 pages of a text to your class to deepen understanding of cell permeability, diffusion, ions, and more. The handout portion includes vocabulary clarifications, detailed color diagrams, and important information;...

Time to turn the heat up on your next bonding lesson! Young chemists explore temperature, kinetic energy, and bonding through an interesting interactive. The controls allow individuals to vary the temperature, as well as pause progress...

To go or to not to go — the question for a mission to Mars. This resource provides details for a possible manned mission to Mars. Details include a launch schedule, what life would be like on the surface, and how the astronauts would...

Sometimes modeling is the best approach to working with microscopic particles. A lab investigation models a fictional element using pasta. The setup uses three different pasta types to represent three different isotopes. Learners...

Many periodic tables mention specific heat, but how do scientists determine those numbers? Scholars attempt to find the specific heat of a metallic element by using a calorimeter. Three experimental trials ensure accuracy, and analysis...

As the most abundant element on the earth, hydrogen requires no replacement. Yet scholars learn to replace hydrogen with a metal to liberate the hydrogen gas. A simple procedure and data table include the necessary information and...

Whether your young biologists realize it or not, humans play a significant role in marine ecosystems. To help them understand this fact children first create graphical representations that show homo sapiens' place in marine...

Six questions make up a mixed practice worksheet. Scholars use their knowledge of addition, subtraction, multiplication, money, perimeter, ounces, and pounds to solve word problems with numbers up to 66,000.

How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

Soften up an egg. Learners use vinegar to test for calcium carbonate in an egg shell and an antacid tablet and compare the reaction with vinegar to the reaction with water. In a second experiment, class members break down an egg shell...

Pupils solve chemical equations. In this chemistry lesson, they balance chemical equations after completing a lab. They can use a TI for this assignment.

Students investigate polymers and their uses in everyday life. In this polymers lesson, students are assigned one of the 10 areas of polymer science and they do research on their assigned area using the internet. Students gather their...

Students prepare an ad for an element, including properties and uses, in an attention getting format such as that used in the advertising business.

Identify the properties of proteins and amino acids. Name the groups of elements that identify an amino acid Describe the chemical structure of protein Explain what happen during the denaturation of protein and how the process occurs

Students participate in a hands-on activity in which they observe the effect of temperature on the rate of chemical reactions. Using Alka Seltzer tablets in different temperatures of water, they record the amount of time it takes each...

Students compare the characteristics of a fired porcelain sculpture to the clay used to create it. They discuss the physical and chemical changes that occur in the clay as it is heated and then create their own clay sculpture. This...

Students find moles and molecules used when a candle burns. In this moles and molecules lesson plan, students calculate the initial mass of a candle and the mass of a candle after it burns for 3 minutes. They calculate the mass lost when...

For this chemical compounds worksheet, students draw and correct Lewis structure for the given compounds or ions. Students draw the resonance structure if applicable. This worksheet has 8 problems to solve.
