Science with Lexi

 What I learned  Today we learned about different models and what they are used for. I thought it very interesting when we looked at two different types of maps and what they are "better" used for. For example, a flat map is misleading instead of a round map.  I learned that when we are picking what type of a model to use, we have to think about how every model has its limits, but picking the best model, we should ask these questions first. - What's involved  - What's not  - What are we looking to answer This is the first model we made to explain why the plunger sticks to the table. We then did an Ice Melting simulation and touched deeper on what we had already done in one of our first labs of this unit. It was cool that it was an online simulation, so students could do it anytime. We then made a flip grid which I  will attach here.  Relation to Prior Knowledge  I knew that a can will sweat when they come from a cooler to the outsid...

  What we learned this week This week in our science lab we learned from a new guest teacher, she taught us about the idea of how things change based on what they are put in. We did M and Ms and we tested what happens when they are submerged in different types of water. One group had salt water, one had normal water (control), and one had sugar water, and hot water (my group). We placed the M&Ms on a paper plate and we put the water assigned to the group in the plate and then the same formation and colors of M&Ms For hot water, we noticed that the color came off of the M&Ms  extremely quick, there was not even a moment of pure water.  The sugar water did not melt very quickly at all, this is at 5 minutes of sitting, because the water had so much sugar already in it there was nowhere for the sugar to mix into. The salt one did not melt at all, this was at the end and there is absolutely nothing We then drew our completed M...

  What we learned this week In this week we learned about different types of matter. We did the mass, volume, and density of many different objects and their size. One example of this is we did different paperclip sizes, one small one and one big one and we tried to see what the differences in them were. I thought it was really interesting how not much changed based on the different sizes of objects. We got to see whether objects were magnetic, floated, sunk, their volume, and their masses of them. This lab was great at showing us different concepts within the concept of matter itself.  Relate what I knew to what I learned Something I knew was that aluminum didn't rust and that it isn't magnetic, this lab really reminded me of how much I already know but it did remind me that I know a lot of things but once you ask me "why" I might get a little stuck. Clear and Confusing The only thing I thought was confusing was when our light kept...

What we learned this week This week we did different stations that all had to do with chemistry and figuring out why certain things happen. We did six different labs, cold soda, plunger push, ice melting, coke float, baking soda and vinegar, and M&Ms in water. During these labs, we did the hands-on experiment at our own pace.  Station 1: Coke Float  We all had a close hypothesis for this station, but none of us were correct. For some reason, the big Coke sunk, but everything else floated. This was interesting; we think it's because the big Coke is denser.  Station 2: Baking Soda and  Vinegar  This station we were all familiar with and have done many times; we knew that the baking soda and vinegar were going to combine and bubble. We didn't realize that when it bubbled and released the air, it became a super cold substance.  Station 3: M&M in Water  This station we were also familiar with this. We knew the M&M c...
