Impacts of Global Change on Ecosystems

CatalystYou want to know which cat food Fluffy (your cat) prefers. You decide to feed him 1 cup of Friskies one day, and 2 cups of Fancy Feast the next day. You repeat this for 3 weeks. At the end of the experiment, there was much less Friskies in his bowl every day you fed him Friskies as compared to when you fed him Fancy Feast. You conclude that he likes Friskies more than Fancy Feast.1. Name the IV, DV, and constants in this experiment2. What are some errors in this experiment?3. What were some things performed correctly in this experiment? Catalyst: Noun: substance in a chemical reaction that increases the rate of reaction (without being used up in the process)Noun: a person or event that causes a change to happen more quickly*Challenge: Use the word catalyst in a sentence with reference to this course.1Experimental ErrorBrainstorm: Sources of errorExperimental error the amount that the measured value differs from the true valueIn other words: How far off is your measurement?

THINK: Why cant we just measure how much Fluffy eats of ONE type of cat food?

Control GroupRecall: What is a control group?Group separated from the rest of the experiment where the independent variable cannot influence the resultsNo treatment is given

CatalystYoure enjoying a nice, cold Coca-Cola with your friend. Your friend throws the plastic bottle into the trash can. After watching the Will.I.am video on Ekocycle:

1. Describe: What is one way that plastic Coke bottle could be reused?2. If you recycle the plastic Coke bottle, what types of plastic products could it be used to make?3. Trace the journey of a plastic bottle from a landfill (where it does NOT break down) to its ultimate destination.

Reduce, Reuse, Recycle and the Carbon Footprint

Ms. Roseman and Ms. Walker

graduating9Reduce, Reuse, RecycleReduce: Limit the amount of materials used to begin with!Reuse:Repurpose old items rather than discarding themBuy used items instead of newRecycle:If the item cannot be reused, place it into a recycling center!

ExamplesReduceUse a reusable water bottle instead of buying a 24 pack of water each week!ReuseShop at thrift stores for items you needRecycle Donate old clothes instead of throwing them away!Put bottles/cans into recycling centers

If we dont RRR, where does our trash go?

Where does our trash go?

LandfillA place where our garbage is taken and buried between layers of dirt

The hope is that the solid waste will ultimately decompose

Paper takes up as much as 50% of all landfill space.

Litter on Land and SeaWhy is this a problem?Well, back in the day, it wasnt!

Human Population and Mentality

Then (20th century)~2.5 billion people

and now~7 billion peopleDilution is not the solutionMore humans, more waste

Why is this a problem?Well, back in the day, it wasnt!Human population, overconsumption, and a disposable lifestyle have led to detrimental effects

How much trash do you generate (make) per day?Americans generate trash at an astonishing rate of 4.6 pounds per day per person= 251 million tons (228 million metric tons) per year

THINK: Whats your carbon footprint? [worksheet]Carbon FootprintThe amount of carbon dioxide (CO2) and other carbon compounds let into the atmosphere (carbon emissions)

Typically due to the consumption of fossil fuels by a particular person, group, etc.

Contributes to global warming

Carbon footprint: area needed to absorb carbon emissions generated by your home energy use and transportation

Use old rags to clean your room or paint with Use Styrofoam, cans, boxes and other containers to make things, like crafts.The next time something is broken try to repair it instead of replacing it The next time something is broken try to repair it instead of replacing it

Have a yard sale with your family or friends. Use cloth napkins instead of paper napkins Make a cloth lunchbox, or use a store bought one to replace paper bags.

In total, more than a million birds and marine animals die each year from consuming or becoming caught in plastic and other debris.
