Physics 1-11-19 Collision Homework

PHYSICS: Here’s a new way to study collisions! Somebody’s having way too much fun with veggies!

How are you doing with last night’s homework? Here’s our look at some of the conceptual questions and a look at setting up some of the homework.

Are you ready to crank it up a bit? Here’s a hint – check for connections between the conservation of momentum and the conservation of energy. You can do it!

Hon Chemistry 1-11-19 Photoelectric Effect

HON CHEMISTRY: Wow check out this awesome example of the photoelectric effect – a giant solar flower in Buenos Aires, Argentina! It moves as it follows the sun. Click on the link to learn more. There’s also a link below the vodcast. Giant Solar Flower

Awesome field trip today! Hey what about other applications of the photoelectric effect? Are there tiny people living in boxes above the doors at Wal-mart and Target? What about solar calculators? And hey – what about those automatic flush toilets?!

Chemistry 1-11-19 Structure of the Atom, Pt. 2

CHEMISTRY: Happy Friday! Here’s the last of our discussion on how scientists discovered protons and neutrons. You know, in class yesterday and today I just gave you mostly one name to go with each, but don’t forget they work with other scientists to get the job done!!

Make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries.

Here’s a video clip that will help you review: The Discovery of the Nucleus. And again – do you think there could be anything smaller than protons, neutrons, and electrons? Hmmmmm……
