A science teacher’s presentation of scientific numbers
How a science teacher presents scientific numbers – presented by a young energetic science teacher. Could either show the video or “borrow” the ideas on showing mass of the sun and mass of a proton as your lesson hook. Good question at the end for students to work out.
Investigating Scientific Notation
An investigation of some real objects using Wolfram Alpha. The worksheets formed the basis of the investigation looking at the mass of a grain of rice, the diameter of the earth, the speed of light and the distance to Proxima Centauri (the star closest to earth).
