    Week 14- Melting Ice   Learning This Week: This week during lab, we discussed the phenomenon why ice melts faster on metal than it does on wood. We started by doing three different simulations do explain the phenomenon. The first simulation looked at the strengths of bonds and their melting points. The weak bonds had a lower melting point compared the the substance with stronger bonds took a higher heat to melt. The second simulation showed how particles transfer heat by bouncing around and hitting each other. It started with red particles on top and white on the bottom, as the red particles bounce around and hit each other, they end up mixing with the white particles and transferring its heat. The final simulation showed the amount of heat that was transferred based on what material it was. The materials included metal, wood, glass, and stone. The metal transferred the heat very quickly and the wood transferred heat the slowest. We concluded our lab section by creati...

      Week 13- M&M Exploration   Learning This Week: This week during lab, we looked further into the M&M exploration activity. During the first week of physical science, we did an M&M lab where we put M&Ms into water and watched the color run off. This week we ran more tests to decide why this happens and what factors can play into it. We started by putting different colors of M&Ms onto a plate of room temperature water and noted which colors "ran off" quicker. To test this, we took pictures of the plate after 1 minutes, and then again after 2 minutes. We noticed that the red M&M dissolved quickest and the blue M&M dissolved the slowest. We tested the M&Ms again by putting them in sugar water and in cold water. We looked to see how these different water types affected the speed at which the M&Ms dissolved. After all of our trials, we saw that (in order from quickest to slowest) the M&Ms dissolved quicker starting in hot water,...

     Week 12- Why does Matter, Matter?   Learning This Week: This week in lab we looked further into matter and its properties. We spend time brainstorming what constitutes as a property of matter. The list we came up with was mass, weight, volume, odor, etc. Then, we took this into an investigation of certain materials to explore their properties. We looked at if the item could sink/float, if it would produce electricity, if it was magnetic, and its mass and volume. Our group looked at six different materials: marbles, aluminum foil, chalk, playdoh, candles, and paperclips. Each material had a big item and a small item. After observing a property for each we recorded the results on the board.  Our Data Table Application to Future Teaching:  Our lab section this week was based a lot on experimentation and observation. I liked how our learning was up to us instead of getting direct instruction from the teacher. This is an aspect that I want to bring into my ...

    Week 11- Chemistry Exploration   Learning This Week: This week in lab we started our chemistry exploration unit and learning about matter. Throughout this class period we engaged with six different exploration stations. The first station my group went to was the M&M's in water, we noticed that the part of the M&M that was in the water started to bleed its color into the center of the plate. Only the portion of the M&M that was in the water was shedding its color. The next station was the plunger push. We noticed that the plunger stuck well to the table and the floor, but did not stick to the outside of the cardboard. The next station was melting ice on three different surfaces: wood, stainless steel, and a non-stick pan. We noticed that the ice melted the quickest on the stainless steel pot, but melted the slowest on the piece of wood. The next station we looked at condensation on a water bottle and what causes that to happen/not occur. Next, we looked at ...
