Methods 2 week 14

 

  1. The big question addressed in lab, and a description of what you did.
We went over our interviews with elders. 
We watched a video called, "The science of Climate change" 
During this video we saw the CO2 levels rise and fall throughout the past and now on a constant uprise.
Greenhouse gas is a gas that absorbs and then reemits. 
We did a simulation looking at greenhouse gasses and its effect. 
  1. A description of what you learned in Thursday's lecture.

We learned about climate change:

Lakes are calm at night because of albedo. 

White reflects sunlight.

Black absorbs light.

Snow reflects more, color absorbs more. 

Informed molecules vibrate, trapping energy. 

Climate science is all about energy. 

A lab that can be done with kids is having different containers that are different colors and seeing which one melts faster. 

Albedo is measured 0 to 1. 1 is totally reflective 0 is totally absorbed. 

Turf is hotter than natural grass. 

Glaciers melt then there is dark water that will absorb more sunlight and heat up.

  1. Answer questions about the weekly textbook reading:
    1. What did you learn?
Climate change is caused by humans (according to MOST scientists). 
The effects of melting sea ice. 
Climate change can also cause very cold temps. 
Climate change causes billions of dollars to try and fix, ex. droughts, floods, wildfires, etc. 
The suns radiation causes oceans to heat up because of the reflection of the water. 
    1. What was most helpful?
The different videos provided that went into depth on timelines of climate change and making videos easy to understand like "Earth has a fever" 
    1. What do you need more information on?
If there is not land under the north pole glaciers and ice what is under it? 
    1. What questions/concerns/comments do you have?
N/A

methods 2 week 2

 Science Methods II Week 2 Grace Stutting The big question addressed in lab, and a description of what you did. "How can we ensure that a race is exciting?" We were able to go off this question in a fun way! We as table groups were able to come up with diverse ideas to ensure a race that included a sorts of ways would be fun and exciting. We were able to use things like running, walking, rolling in a chair, crawling, speed walking or whatever mode of transportation.  This was a very important lab because we were able to create a way that there is still excitement in races when it is evident that not all people are the same speed when running.  A description of what you learned in Thursday's lecture. In lecture this week we learned the importance of measurement, time and speed. This in very important when it comes to units, there are imperial which we use in the US but there is also metric that is used in other countries but it is important for our students to understand b

Methods 2 Week 5

 Week 5 Blog Post  1. The big question addressed and what you did in lab? How can we design a playground surface?                                             (Not sure if these videos will work but they are our slow motion videos of our experiments!)  We used different material to make a surface for an egg to land and not break.  We used rubber pieces, sand and seran wrap.  It worked from one meter up but broke when dropping at 2 meters. This was because our surface area was smaller, and it had more length to drop creating more energy making it bounce off/ out of the bowl landing on the hard floor causing it to break.  Small light thing hitting big heavy thing stays equal forces.  Forces are equal but thing that is bigger will take it better, EX. big car little car crash, bug hitting a moving car, etc.  Newtons 3rd Law: Objects exert forces on each other that are equal in magnitude and opposite direction.  - Forces come in equal parts. "If A pushes B to the right, B pushes A to th
