Lesson 7
What is a feedback loop?
A feedback is a cause and effect cycle that occurs (one event leads to another)
What is qualitative data? What is quantitative data?
Qualitative Data: Data that can be observed using your 5 senses.
Quantitative Data: Data that can be counted/#'s.
What are the 4 types of water that makes up Disko Bay (the Ilulissat Glacier drawing)
*HAS TO BE FROM LEAST TO MOST DENSE*Listed from Least to Most Dense Water:
1. Warm Fresh
2. Cold Fresh
3. Warm Salty
4. Cold Salty
What are examples renewable? (Have at least three examples for full credit)
1. Hydropower
2. Solar
3. Geothermal
4. Biomass
5. Wind
How can we calculate change in temperature? Must write the full equation for full credit
Change in Temperature = Final temp - Initial temp
True or False: All positive feeback loops are good.
FALSE
Example: If we put more CO2 in the atmosphere, what happens to the temperature on Earth (why does it get hotter)?
What are some methods of passing down qualitative data? 🤓☝🏻
1. Talk story (mo'olelo)
2. Seeing changes in land/ice structures over time.
3. Observing the endangered/addition of new plants/animals.
What is density? Give me the definition and equation pls 🤓☝🏻
Density is the amount of space an object takes up.
D=mass (g)/volume (mL)
Why is coal, nuclear, natural gas, and oil nonrewable energy
These are all energy types that can only be used once and it will be gone. 🤓☝🏻
In class yesterday, what unit did we say is also on food labels/nutritional facts on food?
calories 🤓☝🏻
What is a negative feedback loop? ☝🏻🤓
When one event occurs and neutralizes/balances the other event out.
What is a similarity that qualitative + quantitative data share? (HINT: Can we use the same objects to describe an object's qualitative data and quantitative data).
ABSOLUTELY WE CAN :)
Please give us one of our class examples.
What is the relationship between particle movement and different temperatures of water?
(Tell us + model/draw out the particles) 🤓☝🏻
Warm water = faster moving water particles
Cold water = slower moving water particles
True or False: Wai'anae High School uses renewable energy systems (if true, list an example we can observe throughout campus).
ABSOLUTELY TRUE 🤓☝🏻
- We use solar energy to generate electricity through campus buildings.
- Marine Science (directly below us): uses hydropower to regulate oxygen and pH levels in student-led experimental fish tanks. (iydk, now yenno 🤣)
If we were to put in units, "the amount of heat needed to raise the temperature of 1 gram of H2O by 1 degree Celsius" for specific heat capacity, write the correct units for this variable.
# of calories / (grams) x (degrees Celsius) 🤓☝🏻
What is a another misconception/misunderstanding of feedback loops (HINT: the other type of feedback loops)
Not all negative feedback loops are bad.
HINT: What's the example of this that is shown in humans in order to regulate our body temperature?What is the significance behind why we need to know how to take qualitative and quantitative data in our own environment?
Describe how types AND temperatures of water effects the melting of the Ilulissat Glacier.
Due to the density of salty water, it is more heavier than fresh water. If salty _____ water sank to the bottom of the glacier, salty water particles will move faster than cold salty H2O particles. Thus, causing the glacier to melt from the bottom.
Even though nonrenewable energy can't be used again, generally, where does all materials to make these energy systems come from?
FROM MADA EART 🌎🤓☝🏻
- All materials from nonrewable energies are retrieved from Earth to make them.
What could be a possible misconception/misunderstanding between the variables "Q" and "c" in Q=mcAt?
Q and c can both mean "calories" 🤓☝🏻
What type of feedback loop would the microbead solution be?
Teacher's Discretion: USE EVIDENCE FROM NOTES TO BACK UP YOUR STATEMENTS.
How can we apply our knowledge of qualitative and quantitative data to sea level rise?
Teacher's Choice
Make sure to discuss as a group first before giving us your reasonings w/ evidence.
Now tell us... on your last quiz... tell us why ~ 50% of the class said "salty cold water particles move faster than salty warm water particles" 🤯 ... why is this statement ABSOLUTELY FALSE?
Please explain/model your answers to back your teams up. 🤓☝🏻
Why do you think crucial nonrenewable energy systems, such as nuclear, isn't as often used compared to others?
Please discuss with your groups and mention possible risks that could be brought up with the use of these energies.
Now with everything that we know about energy transfer and where it's happening on our glacier, what solutions (berm or microbeads) would be most beneficial to use? 🤓☝🏻
Be sure to discuss with your groups and use supporting evidence (what the solutions do) to help with limiting energy transfer.
