Week 13

Density Info

M&M Investigation (Air temp water)

Hot water

Cold Water

This week, we explored the behavior of matter and density through hands-on experiments. One activity involved predicting whether small or large dice would sink or float in water. Without direct instructions, we used tools provided to calculate the dice's densities—both were over 1, so we concluded they would sink. We also created models to explain density, which pushed us to think critically about how to visually represent our understanding.

We began learning about particles by experimenting with how M&M colors spread in water. Each group designed their own method to investigate whether certain colors spread faster. This open-ended structure encouraged creativity, but it was sometimes challenging to know if we were measuring the right things. Still, the freedom sparked curiosity and led to a range of approaches across the class.

From the textbook, I learned that atoms are always moving and interacting. The M&M dye spreading in water helped me visualize this, and the simulation showed how temperature increases particle motion.

This experience showed me how valuable model-making can be in helping students express their understanding. I plan to use models in my future classroom to encourage deeper thinking and creativity. I also want to foster curiosity and student-led experimentation, even if it feels a bit messy. Letting students explore on their own builds problem-solving skills and ownership of learning.

Question: How does the amount of sugar in water affect the rate at which M&M color spreads? And why do the colors dissolve so quickly?

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...
