Write YES if it is a part of a cycle Write NO if it is NOT part of a cycle After each answers, write down a number 1-3. 3 = VERY SURE 2 = NOT SO SURE 1 = GUESS

Gas that we breathe. All of life needs it. Animals get it from plants. Bacteria help to fix it – make it usable.

1) YES 2) YES 3) YES 4) YES 5) YES 6) YES

It is part of a CYCLE. Here is the Nitrogen Cycle

They are all part of a cycle somewhere. Like the Silicon cycle. The aluminum cycle. The rock cycle.

1) Matter on earth comes from ____. 2) If humans run out of something, we can _______. 3) A lot of matter that humans manufacture ends up ____________.

The box represents all of the ___ on earth. When someone passes a cork to you…. Pass it on to the next person down the line. See how fast you can complete the cycle.

The box represents all of the ___ on earth. When someone passes a cork to you…. Pass it on to the next person down the line. We need HUMAN VOLUNTEERS…

4) The corks going into a separate box after being manufactured represent______ 5) This game describes a problems we have on earth by _____.

REDUCE: Using less of the material to start with. An example of REDUCING would be ___ Make an icon for REDUCE.

How should we change the matter cycle cork simulation to demonstrate REDUCE?

REUSE: Using the same item again or for a different purpose. An example of REUSING would be ______. Draw an icon for REUSE.

How should we change the matter cycles cork simulation to demonstrate REUSE?

Recycle: Breaking down the product into its base materials and using them to construct new products. An example would be______ Draw an icon.

How should we change the matter cycles cork simulation to demonstrate RECYCLE?

Show your knowledge of the similarities and differences of the Three Rs. 1) Make a poster with three sections. 2) Make a beautiful Venn Diagram. 3) Write the lyrics to the song Old MacDonald.

HowStuffWorks: Recycling Aluminum : Video : Discovery Channel HowStuffWorks: Recycling Aluminum : Video : Discovery Channel How Glass is Recycled How Glass is Recycled Watch the film Sequence the events to recycle an aluminum can.

Composting: Recycling organic material so that it can turn back into soil.

Write down which of the Three Rs saves the most energy and which one saves the least energy. JUSTIFY your answer in complete sentences.

Consider Mark Twain. Find an example of where something is REDUCED, REUSED, and RECYCLED. Find the best examples you can. Put these onto a T- Chart.

REDUCE REUSE RECYCLE Example

Find areas in Mark Twain where things COULD BE: Reduced Reused Recycled Look for the best examples possible. Put these on a second T-Chart.
