Math 8L1-We did not have a class today due to the play Math 8L2-We worked in groups on a PEDMAS puzzel.  Once completed students were given the assignment.  This is due tomorrow and I will be marking it. Science 8L2-First class we had a chance to see some lenses.   We also learnt how to draw diagrams for refractions.    Notes are below.-Second class we were in the science lab investigating refraction of light in air and water.   Students worked on the skills of reformulating a question and writing a hypothesis.   Next class we will finish the investigation by sharing and writing our conclusions.  We will also do an extention and look at how liquids with different densities affects the image.  (Thank you to the group who suggested it.)
