Science (Physics): How small is an atom?

Here is another TedEd video entitled "Just how small is an atom?"  It does an excellent job explaining the answer to that question.  The science video compares an atom to the size of a grapefruit and a blueberry.  It is amazing to visualize just how small atoms really are.  If you happen to be teaching about atomic structure, this might help your students understand this particular scientific concept.

Awesome Kids: 3rd Grader's experiment showed interesting results.

This awesome kid bought some potatoes in order to do an experiment for science.  She wanted to soak them in water and watch sprouts come out and grow a potato plant.  The interesting thing was that her first two potatoes didn't grow anything.  This made her curious so she asked questions.  To her surprise she found out that some potato companies spray the potato with chemicals to keep them from sprouting.  She shows the results of her experiment and the experimental process in detail.  I was quite impressed with the questions and answers she came up with.  We need to get all of our students to start asking and answering questions.  Check her video out, shes fun to listen to as she explains the process.

Science (Astronomy): Is it possible to stop an asteroid?

Bill Nye the Science Guy describes how scientists and physicists might be able to stop an asteroid as it comes closer to Earth.  He discusses the possibilities and potential methods of "shifting" an asteroids course.  One thing I liked in the science video is that he discusses some math and units of conversion dealing with weight.  He explains the science and possibilities in a manner that is very easy to understand.  This video might help you as a science teacher visually introduce asteroids to your students.
