Week 10



This week in lab, we focused on reinforcing our learning from the past few weeks in preparation for our cumulative exam tomorrow. We participated in a simulation demonstrating natural selection and evolution. In this activity, each group member represented an organism with with a specific trait, symbolized by different utensils. These traits either helped or hindered our ability to pick up beans (prey). After each round, the organism with the least favorable trait, determined by collecting the fewest beans, was allowed to switch to a different trait (utensil). By the end of the three rounds, we used our collected data to evaluate the hypothesis we had formed before the simulation. This activity illustrated the process of evolution, as the most beneficial traits became more common over time. It provided me with a clearer understanding of natural selection and evolution, making it a valuable learning experience.

The simulation effectively demonstrated how natural selection and evolution interact with organisms, but I still have some confusion about what drives evolution. Specifically, I find genetic drift difficult to differentiate from mutations. Since their definitions seem closely related, I am unsure how they function distinctly. However, I now better understand how natural selection contributes to evolution by favoring traits that increase an organism's chances of survival and reproduction, leading to their prevalence over generations. 

Looking ahead to my future teaching, I see a lot of benefits in using this simulation or a similar activity to introduce natural selection and evolution. It is cheap and cost-effective, easy to do, and provides a hands-on learning experience for students. This approach encourages deeper thinking about how organisms adapt to their environments. In class, we discussed the importance of simulations and technology in education, and I hope to incorporate both into my future science lessons. These tools can enhance student engagement and comprehension, which are essential for effective learning.

    Hey Macy! I thought you did a great job of explaining the simulation and how it is connected to the learning of natural selection and evolution. I would also agree with you that genetic drift is still a little confusing to me. This is a great activity to incorporate in a future classroom as it is hands-on and engaging.

    Hi Macy! I can also appreciate that this simulation was cheap and easy to do while still providing an accurate model of natural selection. I had a fun time trying to get the beans in the cup and even noticed more competition as we changed traits.

    Hi Macy! I really liked how you explained the simulation and connected it back to the core concepts of natural selection and evolution. I agree that this activity is a great hands-on learning experience and cost-effective for the classroom.

Week 3

I was gone from lab this week, out sick. That being said, my lab was the online powerpoint that our professor provided, which helped me learn a lot more about life cycles!  Can you connect what you’ve learned to prior knowledge? Yes, I’ve encountered the concept of life cycles in various science classes throughout my education, from elementary to college. It's fascinating how a seemingly simple concept like a life cycle can be taught at different levels and explored in so many different ways. How can this be applied to future teaching? Hands-on activities, such as using playdough to model life cycles, are valuable for learners of all ages. It really helped me grasp how each stage connects to the next. I hope to incorporate similar activities in my future classroom to support my students' understanding. What questions remain? During "lab", I wondered how a plant like an apple tree transitions from a flower to an apple? Dr. You explained that pollination is the key proc...

Week 14

This week, we explored the particle model of matter by revisiting experiments from the first week of the lab. To start, we refreshed our understanding of particle characteristics by creating models of solids, liquids, and gases and examining how their particles are arranged. Next, each group was given a question to answer, such as "Where did the water on the can come from?" or "Why does ice melt faster on metal than on wood?" My group focused on investigating why ice melts faster on different surfaces. We used simulations to explore this, and we learned that metal is a good conductor of heat, while wood is not. This difference is due to the structure of particles in each material. Metal has tightly packed particles with little space for air, whereas wood has many air pockets between particles. For ice to melt, particles from another substance need to transfer heat to the ice, causing its particles to move. The metal, with its packed particles, can transfer heat more...
