Lab 15


1. What did you learn this week? 

This week in lab, we took a deeper look at the relationship between baking soda and vinegar. In order to do this, we were instructed to design an activity with the people at our table, and our goal was to be able to explain the outcome of the activity and why the two materials react the way they do. To model this reaction, we poured equal parts of vinegar and baking soda into a ramekin. We put the lid on and shook the container before observing what happened. We noticed that after we did this, the mass of the materials actually changed. This was incredibly interesting to us, because theoretically matter is not supposed to be able to be destroyed. We guessed that this was most likely due to a tiny amount of air escaping when the lid was screwed on. 

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

I think this experiment would be really interesting to do with my students. I remember doing this when I was an elementary student by doing it using a volcano model. This was really exciting to me, because it created a much more grand-looking reaction. I think it would be a really great way to make young learners interested in why certain things happen and why certain reactions occur. 

3. What are new or remaining questions? 

I am still confused on why the reaction ends up being cold once this experiment is done. I think this would be a really interesting detail to be able to tell my future students.

    Hi Gabby! Great post! I was also very surprised by the change in weight of the mixture before and after the reaction because we know that this is not supposed to happen. This made me very concerned that our group was doing something wrong. I was relieved when we realized that the lid was not as tight as we thought. So I think it would be a good idea to use more air tight containers if we repeated this with elementary students. I think that a volcano model would be a great idea. My school never made one, but I always wanted to as a kid. I think that that would be a very memorable activity for students. I was also very curious as to why the reaction got colder. I would assume that it would heat up if we had not done this activity. I would like to explore the reasoning further. I really enjoyed reading your post. Thanks for sharing!

    Hi Gabby, I also found it interesting that the mass did change after the reaction. Like you, I thought that the mass wouldn't have changed due to the conservation of mass but I am curious as to why it did.

  1. What did you learn this week?  This week we began by discussing our Week 11 Homework assignments with the people at our table. We talked about the things we learned, the things we found interesting, and any remaining questions we still have. Then, we continued our discussion on matter that we had started last week. This week, we talked about matter and its properties. To do this, we tested numerous objects to see if they would sink or float, conduct electricity, and if their masses and volumes changes when broken. We recorded our findings in a data table and then discussed some things we found interesting as a whole class.  2. How can you apply what you've learned to your future teaching?  I think the activity that we did in class was a really great way to test so many different objects and their components of matter. I think doing something like this in my future classroom would be a great way for my students to understand what kinds of things have different k...
