Week 12: Properties of Matter

-

 

What did you learn this week?

This week, I learned that when things are broken into smaller pieces, the mass and volume decreases, but most other properties will stay the same. I also learned that chalk floats for a little bit, but eventually sinks. Pennies, paper clips, and aluminum foil conduct electricity, but wax, erasers, and wood do not. 

Are you able to apply what you learned to what you already know?

I already knew many of the properties of matter and that they vary from object to object. I didn't know that pennies weren't magnetic, which was pretty interesting because it's made of metal. I thought all metals would be magnetic. I also already knew that pumice floats, but I didn't know why it floats, which was pretty interesting to hear about. 

What are your new or remaining questions?

Not necessarily a question, but I'm curious about what other properties we could test that would show interesting results, like what things float that you wouldn't expect to float - like Diet Coke.

Week 5: Ecosystems, Habitats, and Food Chains (on Zoom)

-
 This week in lab, we learned about habitats and ecosystems and how some places can be both. We also learned about how some animals interact with their environments, like how dolphins create mud walls to trap fish, leading them to try jumping out of the water and landing in the dolphins mouths. Then, we learned about food chains and how they are different than food webs. Food webs are like food chains, but show more than one chain of consumption.  I already knew most of the stuff that we learned. Although, I didn't know the difference between food chains and food webs, I thought they were the same thing. I also was a bit confused on the difference between habitats and ecosystems before this week, but now I understand the relationship between the two.  I could definitely apply my learning on food chains and food webs to my future teaching. I would like to do on lesson on the differences between them and have my students make their own chains and webs, maybe as posters show...

Week 1: NGSS

 This week, I learned what the NGSS is. Before class, I didn't know what it was or how it was relevant to my future teaching. Now, I have a decent understanding of how to read standards and where they apply in the classroom. Iowa is one the many states that has adopted the NGSS, so I will definitely need to be able to read and understand the standards in my future teaching career. One question I have regarding the NGSS is why only some states use it and others use different standards. I think it would be beneficial for all American students to be taught science using the same standards, especially for students that move frequently, so they can pick up where they left off at their previous school. In lab, we also drew our future classrooms with features we want to include. One thing my group included is pod seating, so students each have their own desk, but can also do group work frequently.

Week 2: Characteristics of Living Things

-

 This week, I learned the 8 characteristics of living things and used those characteristics to determine if things are living or nonliving. I also learned that a seed is not a living thing, but it has the potential to be one, with the right conditions.  This can apply to my teaching, as this week has given me some great examples of ways to incorporate hands-on learning in a science classroom by making posters of what we have learned and growing plants to show the different stages and what conditions they need to survive and grow.  After this week, one question I have is what ways (other than making posters) can we help students to remember the characteristics of living things in a fun and hands-on way?
