Science: Making Water

Science: Making Water

Aim: 
To try and make water by using hydro gas vapor.

Hypotheses: 
I think that it will make a popping sound. 

Equipment: 
Hydrochloric Acid, Magnesium, Glass tubes, Bunsen burner 

Method: 
  1.  First gently grab some glass tubes, a big one and a small one. After that get one piece of magnesium, then put it in the small tube. 
  2. Afterwards go to the teacher to get some acid to pour it in the same tube and then put the big tube on top of it.
    Let it sit for a few minutes then quickly try and get the gas on to the burner and try and hear a pop sound.    

Observations: 
What we saw was people using the tubes and opening them and putting the flame on top of a bunsen burner and trying to hear it make a pop sound. 

Discussion:
What we found was that some of the experiments didn't quite work like some others, and some of the sounds were really good popping sounds which were cool to hear.  

Conclusion: 
At the end of the experiment it was cool to do and learn something new that was interesting.

2040

2040 documentary by Damon Gameau.

What are 2 things you learned?
1 Things I didn't know what could/might happen in 2040 and what damage can happen

2 Knowing that there could be more electricity and power. But which we should have more trees because they get cut down and we need vegetation.   

What I would like to see in 2040? 
I would like to see more less pollution and no climate change that can happen to the earth and some electricity that can help.

Science

Aim: To learn about the different emissions of climate change 

1. Methane is a greenhouse gas that is 25 times more powerful than carbon dioxide.

2. Our landfills are growing and using up more healthy land.

3. Electricity can come from renewable sources ( water wind sun) and non-renewable sources like fossil fuels (oil and gas). 

4. Making clothes, car's, electronics, and processed foods creates a lot of pollution. 

5. The carbon dioxide in oil goes into the atmosphere when the car is running.  

6. Clearing the land for farms and farming practices also creates greenhouse gases.

The case of the Barefoot Burgular


In groups of 3 you are going to need to use your forensic knowledge to solve a crime. You must use the web page: Barefoot Burglar Evidence



  1. Determine which of the four suspects is the "Barefooted Burglar"? 
  2. What do you think was the motive for this crime? 
  3. Write the results of your findings and convince a jury of your peers


The Crime

At approximately 7:15 a.m., Friday morning, Mrs. King, the science teacher, thought something was fishy as she walked down the hall and noticed that her door was open. She walked into her classroom and immediately discovered that the small aquarium had been broken and her prized gold fish were gasping in the sink. Beside the broken aquarium were the shattered remains of the pink piggy bank that had been on the shelf above the aquarium. A can of blue paint was spilled on the floor. Footprints of a barefooted burglar led to an open window. Bits of a white powdery substance were found next to the broken, empty, piggy bank. The only other item found was a half-eaten large chunk of chocolate candy.

When the police arrived they immediately began to gather forensic evidence.



Dan the Man

Height : 176 cm
Alias: The General
Dan was wearing a woollen general's uniform with small holes when apprehended in the woods. He claimed to be gnawing on wood for moisture and insects to practice his survival training. His teeth look like a beavers from gnawing. His wife complains that she never has any baking soda due to Dan's compulsion about storing clothes in mothballs. He thinks the baking soda takes away the mothball smell, so he stuffs his pockets with the substance. Also, his wife reports that her giant chocolate kisses continually disappear from the candy cupboard. He blames their dog Patton, an English bull terrier, who patrols the neighbourhood. His neighbours report that Dan loves the military. He was very regimented about playing taps on his bugle every day at sunset until an irate neighbour broke his bugle. Dan has been trying to save money for a new one.
Peg the Leg

Height: 152 cm
Alias: Lucky Lady
Peg is a librarian known for hanging horseshoes and four leaf clovers in her library. Employees say she is so superstitious she insisted on carpeting in the library instead of laying tiles so she would not step on the cracks. She wraps construction zone tape around open ladders so no one can walk under them. Cola bottles litter her office, which she drinks with chocolate chunks. Her teeth are chipped from knocking the bottles against them. She is always throwing salt over her shoulder for good luck and keeps a salt shaker in her purse. Her alibi is that she was busy closing open umbrellas the morning of the crime.



Jake the Jock


                                                                         Height 201 cm
                                                     Alias: Armchair Quarterback

                                                                                         
Jake the Jock is known for quoting statistics on every sport from boomerang throwing to sled dogging. His neighbour report that he is the neighbourhood pitcher for baseball games. Last year a baseball hit him in the mouth and knocked out his front tooth. This has cramped his eating style of chocolate chunks, candied apples, and corn on the cob. His wife claims that on the morning of the crime Jake was rubbing his hands with cornstarch to keep them dry in preparation for an important baseball game.




Lou Lou

Height: 160 cm
Alias: Sweet Tooth
Lou Lou is so addicted to sugar that she never leaves home without it. She loves to bake sweet things and has an entire pantry full of sugar bins. She claims to have been baking her famous chocolate chunk cookies the morning of the crime (although not a morsel of cookie or chocolate chunk was left when the police arrived.) Lou Lou rarely wears shoes, which often causes her to slip and break things, especially her collection of ceramic pigs.

Evidence:
  • Fingerprints: Sticky, 'swirl' fingerprints were lifted from the aquarium and piggy bank. 
  • Footprints: The painted footprints were measured and were for 26 cm feet. 
  • Teeth: The chunk of chocolate candy was collected for examination. It appeared there were teeth imprints.
  • White Powder: The white powdery substance by the piggy bank was carefully placed in a plastic bag and taken to the forensic chemist for identification . It had very small grains and when mixed with Iodine it reacted making the colour brown. It did not have a smell.
Name: Dave                       
Fingerprints: No.
Mouth prints: Has a chipped tooth.
Shoe size: 16
White powder: None found.
Name
Evidence
DanFingerprints: Whirl
Mouth prints: No missing teeth
Shoe size: None
White powder: Baking soda
PegFingerprints: Whirl
Mouth prints: Chipped teeth
Shoe size: None
White powder: Salt
JakeFingerprints: Swirl
Mouth prints: One missing tooth
Shoe size: None
White powder: Cornstarch
LouFingerprints: Arch
Mouth prints: No missing teeth
Shoe size: None
White powder: None

Findings: ( What did you find. Summarise what you have written in the table above)

I found out that nobody had a shoe size, Dan and Peg had the same whirl fingerprint Lou and Dan had no missing teeth


Verdict: ( Who is the burglar and why)

I think that Peg is the burglar because she eats chocolate chunks. Her teeth are chipped from knocking the bottles against them and she throws salt over shoulder for good luck so maybe she cant get caught.
