Mystery Matter # 2: Living or Not?.... Hypothesis: Aim: To test if a "mystery matter" is alive by providing it with water and an energy source. The mystery matter is living because it seems to be able to survive in water as well as consume food and produce waste. Where does life grow ? Experiments: Set up: Bottle 1: 1/4 teaspoon - myster matter
None - sugar/glucose
100ml - Hot water 1/4 teaspoon - myster matter
10 grams - sugar/glucose
100ml - Hot water Bottle 2: 1/4 teaspoon - myster matter
20 grams - sugar/glucose
100ml - Hot water Bottle 3: Bottle 4: 1/4 teaspoon - myster matter
30 grams - sugar/glucose
100ml - Hot water Observations/data: Initial observations- Bottle 1- Bottle 2- Bottle 3- Bottle 4- Appearance Froth/Bubbling Inflation of Balloon Glucose Presence -very cloudy

-Pale cream color -None -None -None -None -None -None Summary: On the first day all the bottles were cloudy, however, on the final observation I realized that the cloudy-ness had settled to the bottom, leaving the top clearer and almost translucent. Throughout the experiment, the bottles were a creamy white sort of color and smelled horrible. There was slight froth in bootles 3 and 4 on the Initial observation, whilst bottle 2 barely had enough froth to qualify it as frothing. Bottle 1 had none throughout. Strangely there was no Inflation of the balloons on all bottles, though bottle 4 had barely a slight inflation on our 3pm obsevation. The glucose presence was a bit more complicated, there was only Glucose presence in bottles 2-4 on our initial observation. (We didn't put any in bottle 1 anyway), we couldn't check the glucose presence on our 3pm observation due to the fact that we might interfear with our balloon inflation data. There wasn't any glucose presence in all 4 bottles on our Final observation. Conclusion: The aim of this experiment was to test if the mystery matter was living or not and to confirm the statement of M.R.S.G.R.E.N.
My hypothesis was that the mystery matter was living because I already saw the finished product and, of course, I was right.

The reasons that my hypothesis was right was because I saw the finished product before stating my hypothesis and because the food we provided for the mystery matter had been consumed. However, I had a few doubts, the balloons on all 4 bottles hadn't inflated at all or just a little bit (in bottle 4's case). The water level did rise so perhaps the mystery matter had forced the water level upward.

I think that the mystery matter is alive because our observations to the experiment prooved that it consumed the glucose, breathed (a bit) and because it ate it most likely excreated (perhaps the frothing) There were a few complications that might have changed the results, first of all the baloons weren't sealed that well and there were cracks in the nozzle of the bottle (Rim). The mystery matter was yeast. Bacteria culture:
Where does bacteria grow ? Bacteria Bacteria Location: Jordan's Pencil case
Date: 13th September 2010
Time: 1:40 pm
Observations: Seems to be everywhere, a beige-ish sort of color with tints of white and yellow. Location: Carla's Fablehaven book
Date: 13th September 2010
Time: 1:40 pm
Observations: Not much bacteria cultivation, digusting and an an off white color. Not all connected. Seperate colonies? First observation- Bacteria Other Colonies Bacteria Location: Jordan's Pencil case
Date: 15th September 2010
Time: 12:55 pm
Observations: There has been more bacteria growth though there's a spot begining to open up. Location: Carla's Fablehaven book
Date: 15th September 2010
Time: 12:55 pm
Observations: Some are deterorating but new colonies are starting to form in a yellow-ish white sort of color. Opening Conclusion: Bacteria grows everywhere including the air we breathe. The perfect breeding grounds are in dark, dirty and damp areas as well as your cell-phone. By: Jordan Kim
Block E Mystery Matter # 1: Living or Not?.... Final observation- Hypothesis: I think that Life can grow anywhere as long as there is air to breathe, nutrients to absorb and water to drink. Characteristics of life: The thing is, there is no single characteristic that fits all forms of life, there is also no single test that can test the presence or absence of it either. There are however, some characteristics that fit most forms of life. Two characteristics that can help (not exactly) determine if "something" is "living", however, is if it can reproduce and create "look- alikes" without any manufacturing on mankind's part. Most living things require water, nutrients and energy. Energy Water Nutrients And And And And And Shelter Conclusion: By these experiments and my collected data, I conclude that life is found everywhere. NASA looks for life by looking for water, "for when there is water there is growth and when there is growth there is life." - Anonymous (actually I don't know who said this) We may eventually change our "definition" of life because life is always changing. That's why the hardest questions to ask is always "What is the meaning of life?" What is the meaning of life?What is the meaning of life?What is the meaning of life?What is the meaning of life?What is the meaning of life?What is the meaning of life?What is the mea ning of life?

Question: Can fire excreate? Note: "MRS GREN" isn't the real way to determine life. vs. vs. Hypothesis: The "mystery powder" is probably not alive considering powder is powder, isn't it?
The Rubber fish is definetely not alive, it's rubber.
The blob isn't alive either, it's just plastic put together. Test 1 (Mystery powder, Rubber fish and "blob": Observations: Mystery powder - it's rather dissolved and something is moving inside the water, some of the boys say that the powder was mosquito larvae. Rubber fish - not moving, staying at the bottom of the jar, molding, slightly puffed up. ----------------------------------------------------------------------- ----------------------------------------------------------------------- "Blob" - It has puffed up into larger ones, it's actually waterbabies, they have water inside them. Set up: Place all of the experiments into it's own jar of water, observe. The mystery powder was live mosquito larvae, the fish sank like a stone and molded, the "blob" was waterbabies. The mosquito larvae was obviously living but the Rubber fish and the blob was not. They puffed up but they still aren't living. Conclusion: Charateristics: - Eats
- Excreates
- Breathes
- Is able to live in water Charateristics: - Reproduces into Colonies Charateristics (Fire): - Moves
- Breathes
- Grows
- Reproduces
- Excreates (?)

- Can survive in water - Expands/Inflates
- perhaps molds Charateristics (Rubber Fish and Water babies): Test 2 (Microscopic cells): Name of Specimen: Source: Magnification: Details: Euglena Prepared slide x43 It's sort of gooey, Single celled, Cell wall not visible Cell membrane Nucleus Cytoplasm Test 3 (Microscopic cells II): Cell membrane Plant Dirt Nucleus Water Slug-like unknown specimen Magnification: Details: Source: Name of Specimen: Micro-organism (specimen) Pond water x40 Single celled, eats (each other), moves (by wriggling) Lives in dirty water Characteristics (Euglena): - Unknown - Lives in Dirty water
- Eats
- Excreates(?)
- Moves
- Breathes(?)
- Grows
- Reproduces Characteristics (Micro-organism): Where can life be found?: Life can be found anywhere, underwater, deep in the Earth's core, everywhere. Some more likely to be found than others, the bathroom for example, you'll find lots and lots of bacteria there. The bathroom and other not very hygenic places aren't the only places, my pencil case had probably even more bacteria than on a toilet seat. Bacteria usually lives in colonies and they breed very fast. The perfect breeding grounds for bacteria is anywhere though most are commonly found in dark, dirty, damp areas. Your cell-phone is another good place.
