Week 15 Blog

                                               Week 15 Lab 05/07/25 

     This week in lab, we started off by reviewing the experiments we did a few weeks ago and talked about which ones we felt the most confident in. I feel the most confident in the condensation, why ice melts faster on wood, and the plunger on the table. I still have some questions about the M&M melting activity because I feel like every time we did it, the results were different. Overall, all of those activities we did were very fun and I learned a lot doing them. Then, we spent an hour designing a lab for students in 5th grade and how matter is conserved. We used baking soda and vinegar and a balloon to show how the mass does not change, even after a reaction happens. However, after doing the experiment with the balloon multiple times, the weight changed. Which was due to buoyancy, and we then pivoted and used a little test tube to drop the baking soda into the bottle and then using the cap and the weight stayed the exact same. Then, we talked with other tables about our experiment and everyone kind of went through a similar thing when figuring out how to keep the total weight of the matter the same. 

    Thinking back to my prior knowledge, I do remember learning about the conservation of matter but I have never done an experiment like this before. This experiment was a really good way to visualize the conservation of matter and also a good way to problem solve since we struggled to prove the conservation of mass to be true using the balloon. 

I can apply what we learned this week to my future career as a teacher in many ways. The first being that this lab was a good way to hone in on my problem solving skills as we could have just said the balloon was "good enough" but with science that is not the case so we had to problem solve how we could actually prove the conservation of mass law to be true and not just "good enough". Also, this is a good experiment I could use in my future classroom with my students. Overall, I can apply what we learned in this lab in my future career.

Week 5 Blog Post

                                         Week 5 Blog 02/19/2025  This week, we had lab on zoom, although we were not able to meet in person, we got a lot done and learned new knowledge and also built on upon prior knowledge throughout our zoom lab. We started the lab by going over the five parts of the 5E model which are: engage, explore, explain, elaborate, and lastly evaluate. We then also talked about the lesson plan assignment for this week just to make sure we all understood what we are supposed to do. We then broke up into small groups and made a small google slides presentation over the 5 parts of 5E and what the teacher does in each part and what the student does. Then, we broke back up into our small groups and went over the reader response from last week which was the NGSS classroom video featuring Ms. Copes class and their lesson over changes to the earth and their ef...

Week Four Blog Post

                                              Week 4 Lab Blog 02/12/2025 This week lab was a little different than usual, we had a snow day so the work that we were supposed to do was assigned asynchronously. We learned about a 5E lesson model and what the functions of each section are. Then, we completed an assignment where we had to find the lesson on NGSS with limited information. Next, we had to define the performance expectation of the lesson, and answer 6 reflection questions in regards to 5E. Then, we had to find and write the scientific and engineering practices, crosscutting concepts, and the disciplinary core ideas.  Thinking back to my prior knowledge, learning about 5E was new to me this week but I found it to be very helpful as a future educator. NGSS, I am somewhat getting familiar with due to this class and us exploring it and learning about it often in ...

Week 8 Blog Post

                                              Week 8 03/12/25 Lab  This week in lab we learned a lot. We looked at our fast plants and observed changes we saw. I noticed that the roots of our plant are changing colors and petals are falling off. Then, we shared the baby we created yesterday to the class and talked about dominant and recessive genes. Next, we learned about DNA, mRNA, and Amino Acid sequences and did two simulations that helped deepen our understanding. Then, we did a superhero worksheet where we changed the DNA of a person and made them a superhero and we talked about how mutation happen. Lastly, we talked about our reader response from last week which was about carbon cycles. Overall, we learned a lot this week in lab.  I can relate to what we learned this week to my prior knowledge as I remember learning about DNA, mRNA, and Amino Acids in high s...
