Week 13



 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 they are going to do in the experiment.

    Hi Alyssa!
    I also was confused as to why some colors seemed to bleed faster than others. I wonder if there is an actual reason, or if they are all different all the time.

    Hi Alyssa! I also want to use this lab in the future. I think allowing the students to have more independence would be good in the later grades, but a little harder in the earlier ones. Great post!

    Hey Alyssa! I am also still confused as to why some M&Ms mix with water differently. I think it has to do with the property of substances, as well as what interacts and attracts with the substance of water. Hopefully, we get more clarity on this!

    Hey Alyssa, I agree with you I struggled with the same thing I would create hypotheses and my hypothesis would be correct but I was not quite sure why. I feel if in the lesson we learned more about the importance of M&M color before the lesson, it might have helped us create a more educated guess!

    Hi Alyssa, it is interesting that we can create an experiment to determine which colors spread faster, yet we don't know why! Maybe I'll go look it up now.

Week 1 Science Methods #2

  Big Question: How do you make an exciting race with a slower and faster racer? What we did: We split up into groups and modeled a race. We thought about what we could do to make the race as even as possible. To do this we measured how fast we could walk a certain distance and then calculated our speed. After doing this in small groups, we returned as a whole class and raced different groups to see if we could make an exciting race. My group succeeded.  Thursday Lecture: In the lecture, we discussed the NGSS that went into the race model that we completed in the lab. We discussed that the SEP was used when we made observations about movement, measured time and distance, calculated speed, and asked a question (The big question). DCI was present when we described motion, measured, and predicted. The Crosscutting concept we used was patterns. The pattern we saw was the prediction we made of our future location based off of how fast we could go a certain distance (speed).  ...

Week #3 Science Methods 2

The big question addressed in lab, and a description of what you did: What affects how long it takes a swing to go back and forth?  A description of what you learned in Thursday's lecture. We learned the definition of the period of a swing, which is the time for a swing to go back and forth once. We then discussed the effect of rider weight and the length of the swing. We learned in the lab that rider weight does not affect the time a swing goes back and forth because of Newton's 2nd law.  We learned about the first two of Newton's laws and how they affect the force of something. F=MA. This makes it clear that larger masses are harder to accelerate, slow down, or turn. We learned that the longer the rope or chain of a swing, the longer the period of the swing.  Answer questions about the weekly textbook reading?       What did you learn?      We learned a fancy word for a swing which is a pendulum. This was a nice reminder that there are...

Solar System Scale

Image
 What did you do in the lab?  In the lab, we looked at the scale of our solar system. We took playdough and a tape measure to create an accurate scale of the sun, Mercury, Venus, Earth, and Mars. After doing this we saw how small and far planets actually are compared to each other and the sun.  The big question:  How big is our solar system? What did you learn in Thursday's lecture?  We learned about the seasons and how they occur due to the tilt of our axis. We also learned that the moon's rotation is identical to the rotation of the earth. Which means that the moon does rotate. The best explanation as to why the moon was created is that a giant mass the size of Mars hit the Earth, this also tipped us over causing us to have seasons. We now know that the Earth has gravity however it is 1/6 that of the Earth. The moon is a quarter the size of the Earth. People are always looking for new answers about the moon. The moon has layers, an outer layer that is light an...
