Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

Let's have a gas. Individuals mix baking soda and vinegar in a bottle. Learners view the interaction between the solid and the liquid and notice that a gas is formed. Scholars notice the gas inflates a balloon stretched across the mouth...

Add a little heat to your science lesson. Young experimenters work to understand the chemical reaction taking place when a candle burns. They experiment with both oxygen and carbon dioxide to make conclusions about the reaction.

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Teach young environmentalists to protect their planet's resources with a set of interactive experiments. Kindergartners and other youngsters learn about watersheds and the water cycle, while older elementary learners focus on fertilizer...

Precipitation reactions are always interesting. How about one that forms a precipitate using a gas? Chemists of any age will enjoy this twist on a standard solubility lab. Partners observe the lack of interaction between sodium...

Energize biologists with colorful images in an activity that captivates the imagination while demystifying the subject of cellular respiration. Participants build comprehension skills and access core content knowledge by analyzing text...

Salinity is the focus of two experimenters that work to answer the question, How does salt change the physical properties of water? Super scientists compare the freezing rate of salt and fresh water, combine the two waters to...

Capillary action is the frugal chemist's dream ... the less liquid used, the more tests they can run! Learners experiment with the best design to maximize the benefits of capillary action. Using a liquid sample, they design a capillary...

Turn your classroom into a pollination station as your kids transform into moths or predators trying to survive and aiding in plant reproduction along the way. Using silent party blowers as proboscises, the moths will have two minutes to...

Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...

Just because we can't see it doesn't mean it isn't there! A growing concern for environmental scientists is toxic nanoparticles in our air and water. Young scholars conduct an experiment to demonstrate how these particles can cross our...

Winogradsky columns are ideal for observing the role of bacteria and other microorganisms in an ecosystem. This student activity guide is complete with data tables for observations and analysis questions for processing what was observed....

Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

An interactive simulation with weights and scales that teaches about balancing chemical equations and conservation of mass. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional...

[Free Registration/Login Required] Move the timer by dragging the red dot in order to observe what happens to the experiment over time. You will need to sign-in to access this interactive, but it will be well worth your time.

An interactive simulation that teaches about chemical reactions and limiting reactants by creating sandwiches to represent chemical reactions. See how many can be made using different amounts of reactants. This simulation can either be...

Simulations that can help students visualize and understand concepts in chemistry like the collision theory, chemical reaction equilibrium, and polymerization.

The University of Arizona's Biology Project provides background information on toxic materials and the body's responses as well as interactive tutorials with assessment questions and an activity in which students can actually acquire and...

This activity is an easy way to demonstrate the fundamental properties of polar and non-polar molecules (such as water and oil), how they interact, and the affect surfactants (such as soap) have on their interactions. Students see the...

Students act as engineers to learn about the strengths of various epoxy-amine mixtures, and observe the unique characteristics of different mixtures of epoxies and hardeners. Student groups make and optimize thermosets by combining two...

A collection of over 30 virtual chemistry problems with accompanying interactive activities. Each problem includes a word file for potential differentiation in your classroom.

Observe how ice and salt crystals interact by using salt to help adhere a string to the top of an ice cube in a glass of water, then lift the cube out of the water.
