Week #4 Science Methods 2




 

The big question addressed in lab, and a description of what you did: How do you design a safe and durable playground surface?

    In the lab, we made a model of a playground surface. We put hay on the bottom, rubber mulch in the middle, and topped it off with hay. We then dropped an egg from 1 meter into the bowl. The egg bounced out of the bowl but did not crack! We learned that it was too bouncy of a surface and if we were going to do it again we would take out some of the rubber mulch. We also wouldn't fill the material to the top of the bowl so that there is some buffer room if it is bouncy and hopefully the egg would be stopped by the small buffer zone. We tried again from 2 meters, Where there was less rubber mulch, and added a little sand. We also left room for the buffer to see if the egg wouldn't bounce out. However, the egg still bounced out but he did survive! 

A description of what you learned in Thursday's lecture.

    It was test day so we did not have a lecture. 

Answer questions about the weekly textbook reading:

    What did you learn?

    Something I learned from the lab this week that I related to our reading from last week was that a formative assessment that is used in science or any subject is walking around the classroom when students are discussing. 

    What was most helpful?

    The most helpful thing from the reading that was applied in the lab was Newton's 3rd law. This wasn't explicitly stated in last week's textbook reading but it was the week before and we did not talk about it, test it, and see it specifically until this week. 

    What do you need more information on?

    Something I would like more information on is Etherm. We learned a little bit about it but I would like to go into more detail to know that I understand it correctly. 

    What questions/concerns/comments do you have?

    Something I want to make note of is that no matter what the force of two things hitting each other is the SAME.

  What did you learn this week?  This week we learned about observation and explanation. We got to observe a few different science experiments. We also made a few predictions. After we made observations and talked about the different kinds of observation (quantitative and qualitative), we tried to explain why what we observed happened which is the explanation.  How can you apply what you've learned to your teaching in the future? I can apply science stations to my classroom in the future. I really liked the idea of doing each experiment and just doing quick little things that are different from each other but are also teaching the same concept.  What are new or remaining questions?  I have a few remaining questions that all have to do with the science stations we went through. Would Coke Zero sink or float in a big can? Were any new chemicals formed when we added baking soda to the vinegar?

  What did you learn this week? This week we learned about mass, volume, conductors, and insulators. We used water in a cylinder beaker to determine the volume of an item. There were differences between the items and differences between the sizes of items which makes for different volumes. I also learned that to accurately determine the volume you have to completely submerge the object you are testing.  How can you apply what you've learned to your teaching in the future? I could see myself using these activities in my future classroom. I especially liked the sink-or-float aspect of the lesson. This was enjoyable and fun. I think students would stay engaged if they did an activity like this.  What are new or remaining questions?  A remaining question I have is how long this activity would take for kids? My group only partially finished our activities and in total it took around 40 minutes for us to do. That's why I was curious about the time frame it would take for our students

  What did you learn this week? This week we learned about density and why some objects have more density than others. We also talked about science models and what a science model may consist of or what it may look like. We discussed that models display a hypothesis.  Which parts did you find clear and which were confusing? One part I found confusing was the reason behind one color of M&M's mixing with the water faster. I hypothesized that the yellow would mix with the water the fastest and I was right but I do not necessarily know why. This was similar to my hypothesis of warm water going faster than cold, which I was also right about but not 100% sure why.  How can you apply what you've learned to your teaching in the future? I can use this lab in the classroom in the future. I really liked the idea of an independent study of the students figuring out how they are going to reach their answers. This makes them more involved in their work since they are determining what the
