week 13


 

  1. What did you learn this week?

This week we learned that density has a role in if an object will sink or float. It depends on the weight in grams as well. If an object is greater than 1gram per mL it will sink. 
We discovered this through our dice activity also while revisiting the coca-cola activity.
I also learned that salt water is more dense than freshwater.

  1. Which parts did you find clear and which were confusing?
I still am a little confused as to how one of the coke cans floated. However, I do understand that they are made up of carbonation and one can had more sugar than the other. Therefore, that could be a factor. 
  1. What are new or remaining questions? 
What objects/matierals are guarenteed to either float or sink?

  1. Hey Mia! Your blog post was very interesting this week! I think the idea of what objects are guaranteed to sink or float!

  2. Hi Mia! I liked your question because I also was thinking the same thing after reading your blog.

  The big question addressed in lab, and a description of what you did. We started lab having small and whole group discussion about formative assessments and teaching students based off of their questions. Next, we did an activity to determine 'who came first' which translates to how we are currently learning about things in earths history that occured first. We did an invesigation to determine what came fist in the principle of superposition.  - rocks form layers that become buried under more layers over time, the deeper we dig, the farther back in time we see. Fossils found deeper and deeper mean it gets older and older.  We also looked at the layers of earth.  1. sandstone  2. mudstone  3. limestone 4. volcanic ash  5. granite (shifts up, lead to fault line)  sand created through water is polished, smooth, similar in size  glaciers, polished, smooth, irregualr in size  wind  A description of what you learned in Thursda...

  The big question addressed in lab, and a description of what you did. REVIEW: Different types of sand:  water (ocean)- polished,  smooth, similar in size  glaciers - polished, smooth, irregular  wind (dune) - opaque, fine grained, frosted, pitted  characteristics of water eriosion  - (1) headwaters, most gravity, moving faster, can carry mroe sediment - (2) TRANSFER ZONE, starts slowing down (3) depositional zone, U shaped river basin  when glaciers move acorss land, make U shaped valleys, not moving super fast  Transitioned into Climate Science  Measuring & Mapping, Precipitation in Iowa  How do we know if the goldfinch is in danger in Iowa?  I think they are starting to become endarged due to the evidence, but slowly. There has been an increase in rainfall which makes it harder for birds to survive.  A description of what you learned in Thursday's lecture. We took an exam during lecture.  Answer questions abou...
