Tuesday, October 31 Today’s agenda: Warm up questions
Ecology - HS-LS2-4 I will be able to use evidence to support the claim that human actions highly impact the environment and I will be able to design solutions to it. Today’s agenda: Warm up questions Mini-interactive lecture Solutions SEP 5: use mathematics and computational thinking Disciplinary core idea: LS2.B: Cycles of Matter and Energy Transfer in Ecosystems Biomass, trophic levels, ecosystems
2
Use this diagram to write THREE claims that explain how carbon gets recycled
3
What is this graph telling you?
4
Warm up Photosynthesizing plants affect the carbon cycle by…
Creating more carbon atoms Reducing the amount of carbon in the soil, reducing soil fertility Absorbing CO2 from the atmosphere, lowering atmospheric levels of carbon None of the above; plants to do not affect the carbon c
5
Warm up Which of the following take carbon dioxide (CO2) in? Plants
Animals Decomposers All of the above
6
Write at least three questions about this picture
7
Would you leave your dog in a car in a hot day? Justify your answer
8
What is a greenhouse?
9
What is a greenhouse?
10
What is the greenhouse effect?
Students might also have experienced this feeling when they get into a car on a hot day. It feels much warmer inside the car because of the trapped air. So, it is different than the greenhouse effect but a connection to their experience. Students might be able come up with other examples as well. Air in the car is trapped and can’t get out. On Earth, there is no physical boundary, so it is the gases that actually work to hold the heat. After these three slides students should be able to fill out the graphic organizer comparing and contrasting a greenhouse with the “greenhouse effect”
11
This is what you have in your guided notes
12
In your guided notes you should have something like this
13
What does the greenhouse effect have to do with global warming?
14
How Global Warming Works
CO2 Carbon Dioxide (CO2) Fossil fuels (coal, oil, natural gas)
15
How Global Warming Works
Carbon Dioxide (CO2) CARBON DIOXIDE (CO2) TRAPS HEAT RAYS Fossil fuels (coal, oil, natural gas)
16
Explain how a car left in the sun in a hot day is like a greenhouse
17
Example of the Greenhouse Effect
The Sun’s energy passes through the car’s windshield. This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.

19
LOOK…Is there a correlation between temperature and CO2 levels?
20
Why should I care?
21
Why should I care? Without the greenhouse effect, the earth would be much cooler than it is now and life would be difficult. However, too much greenhouse warming could raise global temperatures to a level that is significantly different than the current climate.
22
What are the consequences of global warming?
23
Drought and crop failure which leads to FAMINE
Global warming causes the polar ice sheets melt. It increases the sea-level. Flooding will probably occur in lowlands. Many cities along the coast may be under sea water. Hurricanes will become more frequent, intense and will happen in places that currently do not suffer them Drought and crop failure which leads to FAMINE Health issues (due to poor air quality)
24
REMEMBER TO TURN IN ANY MISSING ASSIGNMENT!!
Wednesday, November 1 Ecology - HS-LS2-4 I will be able to use evidence to support the claim that human actions highly impact the environment and I will be able to design solutions to it. REMEMBER TO TURN IN ANY MISSING ASSIGNMENT!! Today’s agenda: What can YOU do? Assessment SEP 5: use mathematics and computational thinking Disciplinary core idea: LS2.B: Cycles of Matter and Energy Transfer in Ecosystems Biomass, trophic levels, ecosystems
25
Global warming: write down three things you already knew and one thing you learned
26
CARBON DIOXIDE So, the main culprit is……
List all the ways that you have contributed to global warming in the last 48 hours!
27
Just think for a moment about how much electricity we all use…..!
So where are these gases coming from? Power stations release huge amounts of carbon dioxide as they burn coal (a fossil fuel) in order to produce electricity. Just think for a moment about how much electricity we all use…..!
28
ELECTRICITY
29
What can you do to help solve the problem?
30
Simple Things To Do Turn off your computer or the TV
when you’re not using it. Take shorter showers. Heating water uses energy. Keep rooms cool by closing the blinds, shades, or curtains. Turn off the lights when you leave a room. Use compact fluorescent bulbs.
31
What’s being done now to reduce our emissions?
Wind Power Solar Power Fuel-Efficiency
32
What can we do to preserve the environment?
