Challenging Concept:<\/p>\n
<\/p>\n
The concept that I choose was one that my grade 4 class struggled with early on in the school year.\u00a0 Understanding the lunar cycle, phases of the moon, along with the tilt of the earth’s axis and its impact on the various seasons was a challenge for them. I used various demonstrations with a globe, flashlight and pictures on the projector.\u00a0 When they completed an extension activity afterwards, many of them still couldn’t explain how those things worked.<\/p>\n
