Watch warm water float on top of cold water in this video segment adapted from ZOOM.
This video segment adapted from ZOOM offers a clever demonstration of buoyancy by showing how to pour a cup of air into a cup filled with water.
Will a grape float in oil? Will a metal nut sink in corn syrup? Watch as the ZOOM cast tests the buoyancy of a variety of liquids and objects.
This activity is a classroom experiment where students make observations, state hypothesis and carry out an investigation to draw conclusions.
This activity is a demonstration proving that carbon dioxide is more dense than air which leads to a deeper understanding of the term density.
Students will design, build and test a hot air balloon of their choosing. Students will construct and test components in order find three component optimum design features for final assembly.

Students design and create their own nano-polymer smartphone or tablet case. Students choose their design, mix their nano-polymer (based in silicone) with starch and add coloring of their choice. While thinking critically about their design, students embed strings in the nano-polymer to optimize both case strength and flexibility. Students may apply strings in a variety of ways in order to maximize their individual design’s potential. Determining the best mixing ratio is also key for success in this challenge.
An engineering design project modified to teach the scientific methos, promote team-builing, and engage students at the beginning of a physics course.
In this video segment adapted from ZOOM, cast members design and build door alarms using a variety of materials, including aluminum foil, batteries, and buzzers.
In this video segment adapted from ZOOM, cast members discover that metal is a good conductor of electricity as they play the steadiness tester game.
This activity is an inquiry lab where students are challenged to create a slow moving and fast moving plane and measure the speed.
In this video segment adapted from ZOOM, cast members make a bridge from a single piece of paper. Will it be strong enough to hold a hundred pennies?
Students find and calculate the angle that light is transmitted through a holographic diffraction grating using trigonometry. After finding this angle, student teams design and build their own spectrographs, researching and designing a ground- or space-based mission using their creation. At project end, teams present their findings to the class, as if they were making an engineering conference presentation. Student must have completed the associated Building a Fancy Spectrograph activity before attempting this activity.
Students begin by following instructions to connect a Sunfounder Ultrasonic Sensor and an Arduino Microcontroller. Once they have them set up, students calibrate the sensor and practice using it. Students are then given an engineering design problem: to build a product that will use the ultrasonic sensors for a purpose that they all specify. Students will have to work together to design and test their product, and ultimately present it to their classmates.
Students acquire a basic understanding of the science and engineering of space travel as well as a brief history of space exploration. They learn about the scientists and engineers who made space travel possible and briefly examine some famous space missions. Finally, they learn the basics of rocket science (Newton's third law of motion), the main components of rockets and the U.S. space shuttle, and how engineers are involved in creating and launching spacecraft.
This activity is a physics lab to detect a magnet's field.
In this video from NOVA scienceNOW, learn how scientists detect potential signs of life on distant planets.
