1. On Target? Do this on your Warm Up worksheet! No warm up today! PLEASE put today’s date (3/25/16) in the Friday box of your warm up, then turn your warm up into the box! Then, sit with your partner, and get out your lab notebook and lab packet!

2. For today 1.Warmup 2.Lab Objective: I can model how carbon moves throughout Earth’s system by completing a carbon cycle lab activity.

3. Carbon Changing Costumes The goal of this lab is to have you model how carbon moves in nature After EACH station you need to add the appropriate arrows to your diagram in your lab notebook!

5. Carbon Cycle Station Lab Checklist: after each station, make sure you have:  Filled out the page in the lab packet  Answered all the questions needed  Added arrows to your carbon cycle diagram in your lab notebook  Cleaned up the lab station

6. REMINDERS Read the alternate instructions/tips at the end of each station! Pay attention to fill lines on bottles and test tubes! Station 2-DO NOT DUMP SOIL DOWN THE DRAIN! Pour out as much water as possible, then put the soil back in the soil tray Station 4-Make sure you zero out the scale with the beaker on top of it and weigh the test tube BEFORE you add your 2 grams (so you can subtract the mass of the test tube! Station 5-PLEASE make sure that you fully rinse out beakers and return the beakers and plastic spoons/knives back to the station for the next group to use. TODAY: DO NOT DO STATION 4!

7. Station 1 This experiment shows that carbon in CO2 moves more rapidly to the atmosphere from _____ water than from ______ water This means that carbon dioxide is more soluble in ______ water than _______ water.

26. Station 8 In the natural world, this experiment represents the movement of carbon from ________ to ________.

27. Station 8 In the natural world, this experiment represents the movement of carbon from _food__ to _atmosphere__.

28. MISCONCEPTIONS! Answer in notebook (you will be sharing these shortly so you need to not be a lazy-bones) 1.Where do plants get the carbon to make sugar (glucose)? 2.How do animals (like humans) get their Carbon? 3.What are the options for CO2 in the ocean to do? 4.Do fish absorb carbon from their environment? 5.Does CO2 evaporate, condense, and precipitate?

29. Find your twin! When I say, find someone that shares a certain trait with you. When you find them, discuss the answer for the question we’re on and if they contribute a different idea, jot it down quickly. – So you’ll need notebook and writing utensil

30. Where do plants get the carbon to make sugar (glucose)? Atmosphere (CO2) NOT from soil Photosynthesis The soil provides other things like nitrogen, phosphorus, and potassium.

31. How do animals (like humans) get their Carbon? Food-not just by magical absorption

32. What are the options for CO2 in the ocean to do? – React with water to make carbonic acid – Taken in by an ocean plant – Outgassing/exosolution (eventually)

33. Do fish absorb carbon from their environment? NO they eat food just like all animals to get their carbon. Stuff in the ocean works just like on land, plants take in CO2 and put out O2, Animals use O2 and eat to get Carbon and put out CO2

34. Does CO2 evaporate, condense, and precipitate? NO: but it can combine with water droplets What happens when CO2 goes into a water droplet?

35. Forms of Carbon Go through your lab packet and circle/highlight any molecule that contains carbon (C) Then, on a whiteboard, work with your group to categorize these into land, ocean, atmosphere, living thing – Place where that form of carbon is found

36. HOMEWORK! Do your Carbon Cycle diagram. Your quiz tomorrow will be asking you to describe the path that a carbon atom could take…

38. Exit Ticket 1.What do you think is the purpose of doing labs? 2.What can you do in the future to make sure a lab is enhancing your understanding of a concept?

39. Warm-up c. __ C 2 H 6 O + __ O 2 → __ CO 2 + __ H 2 O How many on each side to start? Go through and balance 1, then check the others and balance those.

40. What are the options for CO2 in the ocean to do? – React with water to make carbonic acid – Taken in by an ocean plant – Outgassing/exosolution (eventually)

41. Do fish absorb carbon from their environment? NO they eat food just like all animals to get their carbon. Stuff in the ocean works just like on land, plants take in CO2 and put out O2, Animals use O2 and eat to get Carbon and put out CO2

42. Does CO2 evaporate, condense, and precipitate? NO: but it can combine with water droplets What happens when CO2 goes into a water droplet?

43. Go through your lab packet and circle/highlight any molecule that contains carbon (C)

44. Make this table (BIG SPACES) in your notebook Carbon Containing Molecule(s) in... RESERVOIR Carbon Containing Molecule(s) out PROCESS CO 2 Ocean HCO 3 -1 Carbonic acid Acidification CO 2 + H 2 O  H + + HCO 3 -1

45. Help with the table 1.Look at a reservoir (ocean, stream, plant, animal, fossil fuel, etc.) 2. Then go through your packet and figure out what molecule carbon is a part of going in and out (CO2, Glucose, CH4, CaCO3, etc) 3.Write the process by which the change happens (photosynthesis, burning, absorption) 4.*IF you can’t figure out the molecule, do the reservoir and process and we can work on the molecules later

46. List of possible chemicals CO2=carbon dioxide CH4=methane (flamable gas) C6H12O6=glucose CaCO3=Calcium Carbonate (limestone) H2CO3=Carbonate (in water HCO3=carbonic acid)

47. We are going outside! You need to be working on your table Use your packet, drawing, and common sense to figure out what the carbon is in and out of the reservoir. – If you don’t know one (such as what comes out after a fossil fuel is burned) leave the out blank but you should be able to do a lot of these.

48. Outside Expectations 1.What are some “Do’s” and “Don’ts” for going outside? 2.What do you think is an appropriate consequence if people are not following these?

49. Where do the water cycle and carbon cycle meet? (use station # as evidence). How is carbon put into the atmosphere? (use station # as evidence). How is carbon taken out of the atmosphere? (use station # as evidence).

50. Where do trees get most of their mass? Discuss your predictions with your table group. Share out

52. Soooo... Where do trees get most of their mass? THE AIR!! (CO 2 )

53. When you lose weight, where does it go? Conservation of mass means the weight you lose goes somewhere, but where?

54. Use your table to answer 1.How is carbon put into the atmosphere? 2.How is carbon taken out of the atmosphere?
