Week 15


What did you learn this week?

 Today we learned what happens when you increase pressure in a syringe. We got to feel the pressure get tighter when you would keep your finger on the top and push the syringe in. It was harder to push when we had our fingers at the top of the syringe and pulled. We then got to put in a marshmallow and see how the pressure affected the marshmallow. When you pushed the air to make a smaller area with more pressure the marshmallow shrunk and if you opened the space up the marshmallow expanded. 

Which parts did you find clear and which were confusing?

I found it clear as to why the marshmallow shrunk when we added pressure because the pressure pushed on the marshmallow and took the air out of it. I also found it clear as to why the marshmallow expanded. (The opposite reaction and reasoning as to why it shrunk). Something I found confusing is why the marshmallow came out sort of shrunk and wrinkled instead of how it was because everything we did to it we did the inverse too. 

How can you apply what you've learned to your teaching in the future?

Something we learned/did today that I can apply in my future classroom is the guessing activity of what is in the canister. I like how you provide them with all the resources you just do not tell them. This way they get to figure out how to do the investigation and in the future, they will know to think outside the box and use their surroundings.

    Hey Alyssa! I also thought the marshmallow activity was a great activity to show students to concept of pressure. I also want to incorporate this activity in my future classes.

    Hi Alyssa! I also liked the canister activity and want to use it with my students in the future! It is a great way to get them thinking of ways to determine what an object is or if two objects are the same without being able to see the object. Great post!

    Hi Alyssa, it is interesting that the marshmallow expanded as you opened up syringe, I wonder why that is?

Week 11

  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
