Design and construct buildings with rooftop gardens. Junior engineers work in groups to build two buildings and then perform experiments to determine whether or not a garden affects the building's temperatures. They graph and interpret...

Construction leads to habitat loss and local wildlife suffers. Scholars must build a reptile egg incubation device that meets many constraints. Various experiments help them discover the chemical reaction needed to reach...

Build problem-solving skills with science! Step-by-step videos walk investigators through each stage of completing a science fair project. Scientists learn to formulate a testable question, design an experiment, collect data, draw...

Brainstorm ideas to design a sustainable guest village in the Sonoran Desert. The first installment of a nine-part unit teaches young environmental scientists about the basics of the Saguaro National Park and about sustainable design....

Putting glow sticks in the freezer makes them last longer, but why is that? Lesson focuses on how temperature impacts the rate of a chemical reaction. It begins with a teacher demonstration, then scholars design their own experiments...

Take your class up, up, and away with an engaging weather balloon simulation! Individuals get hands-on experience in creating and launching their own airborne labs to study how temperature and pressure affect substances at 100,000...

You're getting warmer. Groups conduct an experiment to determine which of four chemicals are in hot/cold packs. They learn about exothermic and endothermic reactions and use this knowledge to design a hot/cold pack that is small enough...

Do you find the idea of having a science fair with all of your students intimidating? Use a guide that provides everything you need to know to make project-based learning manageable. The resource includes options for four...

How does dirty water get clean enough to drink? After viewing a PowerPoint that outlines the process water goes through at a water treatment plant, groups work together to design a chlorination chamber for a treatment plant.

Get things moving with this extensive collection of physical science resources. Covering the fundamentals of measurement, graphing, lab safety, and experimental design as well as the specific scientific concepts...

Now it's time for all of the data collected in previous lessons to be applied to the design of a rain garden. This resource can only be used as part of the greater whole, since learners will need to rely on gathered knowledge in order to...

Don't just sink the boat. Using a closed container as a submarine, pupils experiment to see what to add to the container to make it float, sink to the bottom, and hover in the middle. After finding one option, learners see if they can...

Students explore botany by participating in a seed experiment. In this plant nutrition lesson, students define several science experiment vocabulary terms like observation, treatment, and replicate. Students utilize soaked seeds in a...

Learners apply their knowledge of friction, drag, mass and gravity as they design, build, and test mini-bobsleds.

The inside of the spacecraft Messenger, which explores Mercury, will experience temperatures from 32 to 91 degrees Fahrenheit. In the final installment of a series of four space-related activities, groups spend time discussing and...

Encoding What I did Last Summer. Class members develop a way to encode a personal experience using a top-down approach to determine components and sub-components of their experience They then pick one portion of the experience and go...

Waxed paper, newspaper, or aluminum foil? Keeping an ice cube from melting may require one or more of these materials. Learners design a box that will provide insulation so an ice cube stays intact for at least 90 minutes.

Students explore the concepts that enable them to design and conduct sound scientific experiments. They critique a faulty experiment and become familiar with some of the criteria of a good experiment. They conduct their own experiment.

What will it take to explore space? Teams of pupils determine the needs of a lunar outpost and research the required systems. The pupils then learn about the past space exploration vehicles. The third and final lesson challenges project...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

Does sound travel faster in water or in the air? Put the question to the test with a science experiment. After reviewing a table of data, third and fourth graders decide which statements are true and which ones are false. The bottom of...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...
