Week 8

 

What Did You Learn This Week?

This week, we revisited the babies we created in last week’s activity. We learned that dominant genes have a 75% chance of being inherited, while recessive genes have a 25% probability. Additionally, we discovered that dark skin color is linked to the dominant gene, which is directly passed down from the parents. This relates to genotype, the combination of alleles an individual has for a specific gene. The genotype influences the phenotype, or the physical expression of traits—such as skin color in this case.

How Can You Apply What You’ve Learned to Your Future Teaching?

I can incorporate what I learned into my future classroom by having students participate in the same simulation we used. This activity demonstrates how DNA codes for proteins, allowing students to observe how codons (sequences of three nucleotides in DNA or RNA) encode specific amino acids. The simulation also illustrates how mutations can occur, impacting genetic traits. This hands-on approach aligns with NGSS standards, as it encourages students to construct models and develop their understanding through real-world applications.

How Does This Connect to What You Already Knew?

I can relate this week’s learning to my past biology studies. In class, we used Punnett squares to predict dominant and recessive traits. I was already aware that mutations can alter genetic traits and chromosome structures, but I hadn’t realized the many different ways mutations can occur. Additionally, while I was familiar with the concept of evolution, I now understand that mutations drive evolution through the process of natural selection.

^ answer for #1 is C instead of D.

    Hello Macy, I found it very interesting that dominant genes have a 75% chance of being inherited, while recessive only have a 25% chance. This fun activity helped me to understand why blue eyes are so uncommon and how skin color is determined. Like you I would love to include the DNA simulations in my future classroom. I think the baby activity would also be useful in a classroom when learning about reproductive and how traits are inherited. I really liked how you connected the hands on activities we have been doing to NGSS. Great post!

    Hi Macy! I enjoyed looking at your blog this week! I like what you said how it is important for students to apply their learning to real life situations. I think that the baby activity that we did is a great way for students to think about their own genes and how this relates to our lives.

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...

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 ...

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...
