Biotech in a Bag

Student demonstrate knowledge of recombinant DNA techniques (restriction enzyme digest, gel electrophoresis, and staining gel). They demonstrate skills needed to complete a gel electrophoresis and interpret a stained gel. Pupils solve...

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this lesson: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium with cobalt...

Does mass change during a chemical reaction? Demonstrate the Law of Conservation of Matter while encouraging class members to be creative with a two-part lesson. First, learners use Alka-Seltzer® tablets and water to demonstrate the...

Learners use the internet to research Archimedes' principle of buoyancy. In groups, they summarize the principle and share it with the class. They also participate in experiments in which they test the principle and share their results...

Students are introduced Bernoulli's Principle and how it shows the relationship between fluid speed and pressure change. In groups, they participate in experiments in different processes in the industrial world. They share their...

A blow dryer and ping pong balls are all you need to demonstrate the amazing properties of air flow. In this demonstration, Spangler has a three year old boy as his assistant. Together, they make ping pong balls, a beach ball, and a roll...

What if buildings could grow, adapt, and repair themselves like a living organism? Using the process of self-assembly, this crazy idea may one day become a reality. The video looks at how unordered parts interact with one another and...

Demonstrate lift to the class that is studying aerodynamics. In the stream of air produced by a blow dryer, little physicists place a wad of tissue paper and a spherical figure to compare. Or, if you have a vacuum cleaner and beach ball,...

Not sure how to introduce young physicists to the Heisenberg Uncertainty Principal? Well this short video is a great place to start, as it explains how the particle and wave nature of matter makes it impossible to know both the...

Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...
