How do you measure big forces accurately? By calibrating your force transducer on the world’s biggest weight – 1,000,000 pounds of force. This machine ensures planes don’t break apart, jets provide required thrust, and rockets make it to their destination. Continue reading
Concept attainment exercises often use verbal or written forms of thought. The attached student exercise uses visual imagery to teach the concepts of Elements, Compounds and Mixtures at the atomic and molecular level. Continue reading

In 2020, NASA will send a new rover to the Martian surface with one of its objectives to search for evidence of ancient life on the planet. I made this clip as a correspondent for Bill Nye Saves the World on Netflix. Continue reading
The contest is to have students design an elemental tile for each of the four newly named elements, nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og). Voting for the winning tiles We are now down to the final four! During the month of May, we will have an online vote to decide which of the final four will be added to our Periodic Table Project. Encourage your students and all chemistry enthusiasts to check out the creative work done by high school students.
Check out the source link below for details on how to vote.

This demonstration shows some differences between potable (drinkable) water and non-potable (non-drinkable) water. Variations in temperature, turbidity and pH level also determine the types of microorganisms that can thrive in each water sample. Continue reading
On April 26, the Cassini spacecraft flew closer to Saturn than ever before — between the gap that separates the planet from its rings.
Since then, Cassini has been transmitting dozens of images of Saturn’s surface. Here, NASA has compiled all the images into one, incredible video that reveals exactly what Cassini saw.
One of the sights that surprised scientists most was the sharp edges of Saturn’s hexagon and its central vortex. Saturn’s hexagon is a giant cloud system on Saturn’s north pole, and it contains a central vortex.
The sharp edges scientists saw in these latest images suggests that the cloud system and its vortex are not mixing with their surroundings. But what’s preventing the clouds in the hexagon from mixing with the clouds right next to it is a mystery.
This first dive marked the beginning of the end for Cassini. For the last 13 years, Cassini has explored Saturn and its moons. But its time will come to an end this September, when it will enter Saturn’s atmosphere and burn up.
