Antibiotic Resistance in E. coli

Students observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...

First, young chemists practice polymer identification by density and flame tests. With the data collected, they propose a method of separating polyethylene from other plastics and determine what property makes it desirable for recycling....

Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....

How can one easily classify metals, nonmetals, and metalloids? Pupils answer this question as they experiment with unknown substances and perform tests on conductivity, brittleness, and malleability to determine...

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

Bring algebra to life with scientific applications. Math minded individuals calculate and graph the time it takes a bacterium to double. They discuss geometric sequences and use a chart to graph their findings. There are 38...

Lead your class in a fun-filled team activity that encourages collaboration while learning important concepts. Pupils actively participate in a discussion on the experimental design and the role of mirrors. They perform group activities...

Nickel resists corrosion, allowing it to be used as one of the elements in stainless steel. Nickel stars in the video, the 28th in a 118-part series, filled with facts and curiosities about this metal. The presenters attempt repeatedly...

Though not commonly searched for, this is a vivid demonstration of how a fuse can be blown, or rather, how resistance works in an electric circuit. You will basically set up a circuit with no lights or bells or motors, allowing the wire...

What would it be like to be stranded on Mount Everest? Curious learners view a video clip, test common fabrics to see how they stand up to cold, and develop/answer discussion questions.
