Week 15 - Conservation of Mass

What did I learn? 

Today we got to use vinegar, baking soda, and bottles to measure the reaction of the two being mixed together. We were observing the way the mass is conserved when things are mixed. My group chose to investigate whether the reactions that occurred would differ in the size of the bottle. We used the same amount of vinegar and the same amount of baking soda in each bottle. We also measured the mass with the limp balloon on the bottle both before and after the reaction. We found that there was a difference but it was less than have a gram that decreased from the mass. 

How can you apply what you learned to your future teaching? 

In this weeks lab, we were given the option to choose what we wanted to collect data over to see how mass might change when you have two things mixing together. It made the experimenting really fun and exciting as we got more freedom and flexibility with what we were observing. 

What are new or remaining questions that you have? 

I'm still confused and unsure as to why the mass changed as we assume that it will stay the same as nothing is leaving the bottle.

    Hi Maddy, My group did the same experiment and found the same conclusion. It is interesting to see how other experiments compared.

    Hi Maddy! I like that you pointed out that being given freedom and flexibility made the experiment that much more engaging and fun! I definitely think that's something to keep in mind when considering how you can apply that in the future!

Week 8 - Genetic Materials

  1. What did I learn this week?  This week, we continued talking about DNA and how DNA is the blueprint for living things. We watched a few videos explaining DNA and how it's located within the nucleus of a cell. DNA looks like a twisted latter that has bases paired together. We talked about how Adenine is paired with thymine and cytosine is paired with guanine. It seems like a twisted ladder and we were actually able to participate in an activity where we created our own strands of DNA. We mix and matched the sides that bases were on and even twisted it to create something that actually looked just like DNA! We also took a look into creating our children and used a coin to determine the genes that the parents had. It was very similar to an activity that I did back in 7th grade where we did something similar. It puts a different perspective on genealogy and how hard it is for recessive traits to be passed down to offspring.  2. What parts were clear and what were confusi...

Week 11 - Chemistry

M&M's in Water  Are you able to relate what you learned to what you already knew?   During the stations, we were using terms to describe what we were observing. Some of the observations were things that we already knew, or things that we predicted and expected to occur from these experiments. Some of the experiments felt very familiar to me and like i've done them before, but it was definitely fun to get to participate in them again.  What did you learn this week?   This week in lab we went around to different stations observing different things that we noticed happening, how we could explain these happening to students, and came up with questions that students might have come up. It was cool to observe and take note of all the things we we observed from the different stations, connecting what we predicted and expected to happen to what actually did, and tired to make sense of it all just as our students would.  Cold Soda Station How can you apply what you l...
