Addy- Science Methods 1

  What did you learn this week? This week in discussion, we were asked to create a lesson for fifth graders using baking soda and vinegar to help answer a question about matter. Our table group had a lt of trial and error when doing this experiment. Once we finally figured out how we should do it, we put baking soda into our balloon and weighed it and it was  0.561 ounces. Then, we measured the vinegar in the water bottle and it ame out to weigh 3.002 ounces. Then we put the balloon onto the bottle and dumped the baking soda into the bottle and the balloon inflated. The mass should have been 3.563 ounces but, it ended up being 3.507 ounces. Are you able to relate what you learned to what you already knew? I was able to relate some of it to what I knew. I knew that vinegar and baking soda would react in the way it did, but I could not fully understand why it weighed less than what I predicted it to. After we discussed it in class it began to make more sense and then it would be...

  What did you learn this week? This week we talked a lot about the states of matter, which are solids, liquids, and gases. We did some simulations to help see the particles and how they differ from one another. The solid particles stuck to their neighbors and wiggled back and forth. The liquids moved around a little more and faster. The gas particles moved everywhere, all going at different speeds. We then made a flip video explain why ice melts faster on stainless steel versus wood. Are you able to relate what you learned to what you already knew? I knew most of these things regarding the properties of matter, but the one new thing that I did learn was really why ice melts faster on stainless steel versus wood. Its because stainless steel has more points of contact than wood which makes it melt faster because the particles are moving quicker. How can you apply what you've learned to your teaching in the future? I can do the ice experiment with my students. I can also show them si...
