Blog Post Week 15

 


1. This week in lab, we designed a learning activity that looked at what happens when you mix vinegar and baking soda. We learned how to develop a question, describe how students might collect and analyze data, and how students should use evidence collected in their investigation to answer the question. The question that we asked students was, does the baking soda completely disappear when you add the vinegar? Where does it go? I learned that it is important to use plan language questions. We figured out the ratio of 1:2 with the baking soda and vinegar to make sure the baking soda completely dissolves. This way, students will be curious to see if the mass stays the same and why this is. The mass will stay the same. 

4. I can apply what I have learned to my teaching in the future. I would like to use a similar experiment with future students where they investigate if mass stays the same during a chemical reaction. I will make a few changes to our experiment by making sure nothing escapes the bag when we close it. This way, the mass will stay the same. I will do this by putting the vinegar and baking soda on separate sides of the bag where they do not touch and close it carefully after this. I will also used what I have learned by developing simple questions that will develop student interest. 

5. Is it possible to get the exact same mass before and after mixing the vinegar and baking soda together?

How can you test a students knowledge based on this experiment?

Would it be more beneficial to do this experiment as a whole class or in groups?

    Hi Abby, this is a great post! I really like your questions at the end. I think it would be interesting to see students complete this experiment and see if they had any more ideas of how to make sure all the matter stills captured. I think ideally it would be best for students to do this in groups, but if you wanted to do it with a younger grade maybe have the whole class observe.

Week 13

  What did you do in lab today? In lab, we looked at various graphs of different climate change. We found from the measurement of different variables that climate is overall warming in our area. These graphs showcased a longer growing season, wetter spring, more summer precipitation, wetter springs and summers, higher humidity, and drier autumns. We also looked at how climate change has affected the growth locations of different plant species.  What was the big question? How is climate change specifically happening in Iowa? What did you learn in Thursday's discussion? In lecture, I learned why some regions have a hot climate while others have cold. I learned that one of the factors that plays a role is latitude and that places closer to the North and South poles will have colder temperatures while places near the equator will have warmer temperatures. As well as this, the temperature of an ocean current will affect the temperature of the air that passes over it. Elevation also...

What did you do in lab today? In lab, we first looked at the law of superposition. I learned that this law says that rock layers closer to the surface are younger than rock layers at the bottom. This is the way geologists find the relative dates and ages of different rocks around the globe. We looked at several visuals that showed the law of superposition and determined the oldest to youngest order of the rocks. Through this, I learned that an intrusion or igneous dyke, which was showed in many of the visuals, has to be younger than all the things it's going through. This is because the rocks had to be there before the intrusion went through them. We also reviewed erosion and sand. We had the opportunity to view several different sands under a microscope and learned where each was form.  What was the big question? What is the Law of Superposition? What did you learn in Thursday's discussion? In lab, we examined water displacement/buoyancy. I learned that buoyancy is the ability...

Blog Post Week 1

  The big question addressed in lab, and a description of what you did. The big question that was addressed in lab this week was, why should elementary students learn about science? Another was, how should elementary students learn about science? After discussing these questions, we watched a video of students playing on a playground and noted what we noticed and wondered. Following this, we explored how we can support play that is exciting but not dangerous. To explore this question more, we did an experiment on how to make a race exciting by ensuring the racers will cross the finish line close to each other. To do this, we measured the distance of our race and the time it took us to walk this distance. After figuring this out, we were able to determine how much time one racer should start before the other to make the race close.  A description of what you learned in Thursday's lecture. In Thursday's lecture we looked at the SEPS, DCI, and CCCs that are in 3-PS2-2. ...
