Week 9


In this lab we reviewed questions for the exam on Thursday. We then mapped out the timeline of the creation of earth, and life. We mapped out on the timeline starting with the big bang, then started at the creation of earth, the moon, first land life, plant life, dinosaurs, and lastly humans. We all guessed on where we thought they would be. We then went on the earth viewer website and found the actually dates. We put them on the timeline then discussed it as a class and realized how off we were. 





Old Lab

13.7 billion years ago is when the big bang occurred. 4.65 billion years ago is when the earth was created, our sun will last for ten billion years. There was a star that existed between the big bang and the creation of our sun. But because it was a huge star it burnt its fuel fast and a supernova occurred. The debris from the first star came together and 99.9 percent was gobbled up by the sun and the last one percent of the debris is what created the planets. We did not come out of the big bang, we are a biproduct of a solar system that used to exist and destroyed itself.

Week 4: Gravity/Swing

  Week 4 Big Question: Main Takeaways on slide and gravity: Weight is how much gravity is pulling down on an object.  When thinking about how things fall weight matters. But air drag also has a huge effect. a crumpled piece of paper, and a loose crumple of paper fall at different rates but have the same mass. The tight crumpled piece of paper has less air drag than the loose paper.  Air drag can cancel almost all or most of gravity on the loose paper. The heavier an object is the longer it takes to slow down or speed up. Gravity does pull harder on objects with more mass, but adding air drag and the time it takes for heavier things to speed up and slow down cancels the forces and makes it even. A rider who weighs more will finish the slide at the same time as a light rider. Because the time it takes to speed up or slow down an object of greater mass, and air drag cancels out the competition. How can we support play that is exciting and not dangerous? What affects a riders...

Week 7: Solar Systems

-
  Week 7  Lab We began by discussing our homework on misconceptions. We talked about strandmap and the purpose of it, and how we can combat misconceptions. We then as a group created a model of the solar system with playdough. We calculated the numbers to try to ensure that they were to scale for distance and size. It was so interesting and shocking to see how far we had to place each planet. Our group had to go into the TLC to measure the distance and it was so surprising how far they were from each other. This was a great activity to use in the classroom to help children understand the distance between each planet.  This activity made all of the misconceptions of what we learned in elementary school seem crazy. The solar systems we would make in class on hangers were no where near accurate in size, or distance. This activity is a great alternative for children to see the accurate sizes and distances. Especially the distance between the sun and the planets.  The vid...
