Using the "magnetic" strips we made in class yesterday, we created a model of the Atlantic Ocean sea floor and saw how new crust could ooze through a crack in the floor and then spread away from the center, causing the sea floor to spread. We then talked about how the iron in the new rock material would align to the poles as it hardened, causing magnetic stripes to appear in the rock material. We will continue to use our sea floor spreading model in class for the next week or so.
In math, we shared multiple ways to figure the percent discount something is. Some students shared a fraction-based approach, while others used an algebraic approach. Both are fine ways to solve percent problems. Hopefully, having more than one way to complete a problem will help students with their future attempts to complete problems involving percents.
Tonight's Homework:
Math--ACE 5 (1-6 and 17)
Science--Read pages 88 - 94 and then answer the 4 questions on page 94.
