Extremophiles are organisms that are capable of thriving and surviving in environments that would usually be detrimental to most organisms on Earth. The extremophile shown below is Pyrolobus fumarii. It is a hyperthermophile, meaning it can withstand extremely high temperatures. Pyrolobus fumarii was first discovered in 1997 in a black smoker hydrothermal vent at the Mid-Atlantic Ridge, setting the upper temperature threshold for known life to exist at 113°C. Strain 121, a microbe from the same family found at a vent in the Pacific Ocean, survived and multiplied during a 10-hour interval spent at 121°C in an autoclave. It was finally killed at a temperature of 130°C.

HOW TO MAKE A BED
1. Put the fitted bottom sheet in place. Pull the fitted bottom sheet elastic tightly and evenly over the mattress corners. Smooth from the center, then tucking under the sides.
Objective: To successfully make a bed in a neat manner.
Materials:
-fitted sheet
-flat sheet
-pillows
-blanket
-pillows
-blanket
1. Put the fitted bottom sheet in place. Pull the fitted bottom sheet elastic tightly and evenly over the mattress corners. Smooth from the center, then tucking under the sides.
2. Add the flat sheet. Spread it out evenly across the bed, allowing any extra to fall at the bottom edge. Tuck in the bottom edge. Pick up the side edge at the bottom corner and hold it out. Tuck in what is left hanging down at the corner, then let the edge fall and tuck it in as well. Repeat for the other bottom corner.
3. Put blanket over the sheets. Place blanket right side up with the top of the blanket at the point where you turn down the flat sheet. Fold down the top sheet over the top edge of the blanket. Now the good side of the sheet is showing. Tuck in the entire side by the wall.
4. Fluff out the pillows and place them at the top of the bed.

Plant Growth Journal
Day 1 (February 14, 2011): My seed was planted. I named it Tina.
Day 2 (February 15, 2011): I watered Tina. Friends told to talk to the plant, so I did that as well.
Day 3 (February 16, 2011): Still no signs of growth. I did not water Tina today for fear that I would rot the seed.
Day 4 (February 17, 2011): I think i over-watered Tina. I am sad :(
Day 5 (February 18, 2011): I got a new seed and planted it. Its name is Tina, Jr. :)
Day 6 (February 19, 2011): It's my birthday. I did not water Tina, Jr. for fear of of over watering the plant.
Day 7 (February 20, 2011): I watered Tina, Jr. No growth yet.
Day 8 (February 21,2011): Still no sign of growth.
Day 9 (February 22, 2011): I decided to put Tina, Jr. outside Maybe she will get more sunlight this way. I also watered the plant.
Day 10 (February 23, 2011): I forgot to check Tina, Jr. today.
Day 11 (February 24, 2011): I went to check Tina, Jr. this morning and I found out that my sister threw my plant away! She thought the random cup on the porch was trash!!! :(

Deductive and Inductive Reasoning
Although often misused by people, inductive and deductive reasoning are actually quite opposite. After the class lecture on inductive and deductive reasoning, I just realized that I, myself, had been using the terms of logic incorrectly. Inductive reasoning is “reasoning from a specific case or cases and deriving a deriving a general rule. On the other hand, deductive reasoning “assumes that the basic law from which you are arguing is applicable in all cases.” Overall, inductive reasoning makes conclusions and assumptions from observations in order to make generalizations about something while deductive reasoning begins with the generalizations and “deduces” specific instances. Use of the following reasoning techniques helps one to make more educated guesses and think more effectively.
