Earthquake proof house

Was it successful? Why/Why not? NO, because my teammates put a stick platform under the base of our house which made it slippery.

What do architects to make super tall buildings safe? Thicker walls and a lot of reinforcement. They put a make sure they put a strong foundation to keep the building from swaying because of strong winds.



 Empire State Building height: 373m, 443m to tip. The American Society of Civil Engineers named the Empire State Building one of the Seven Wonders of the Modern World.

Acid carbonate+ Carbonate --------- Salt+Water+Carbon dioxide expirement

Equipment:

• 50g of sugar 
• 1 tablespoon of golden syrup
• 1/2 teaspoon of bicarbonate soda   
• 1/2 tablespoon of water

Method:

• Put the ingredients except for the bicarbonate soda into a saucepan and place on a low heat
• Stir until all the sugar has dissolved. Raise the heat slightly so that it bubbles, and stir occasionally until you cannot feel any sugar at the bottom of the pan
• Take off heat
• Add bicornate of soda and stir!
• Watch what happens- it should all froth up with bubbles in the pan
• Pour out into your tinfoil sheet
• Allow to cool 

Observation:

Carbon dioxide experiment

Aim: To show that carbon dioxide gas is produced when a metal carbonate reacts with acid.

Method:

1. Light your Bunsen burner
2. Ass a 'pea-sized' amount of metal carbonate into one of the boiling tubes.
3. place the boiling tube into a test tube rack. Ensure you have the bung and delivery tube ready
4. Add 5 mL of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube.
5. Holding the other boiling tube with your tongs, capture the gas produced as shown in the diagram below.
6. When you think the tube is full, your lab partner should light a wooden splint
7. Carefully remove the boiling tube from under the delivery tube, taking care to keep it facing upright
8. Insert the burning splint into the mouth of the test tube.

OBSERVATION:

E1 - When we put the burning splint in the test tube, it got extinguished due to the presence of carbon dioxide.

E2 - We also tried it with lime water. The lime water turned from colourless to cloudy and it starts bubbling.

Science Expirement

Aim: TO make a metal oxide and observe the difference in properties of the product compared to the reactants.

Equipment: Magnesium, Bunsen burner, safety glasses, metal scissor tongs.

Method:

-Light your bunsen burner
-Hold your piece of magnesium in the scissor tongs. Ensure you are holding onto the very tip of the magnesium.
-Place the other end of the magnesium into the Bunsen flame (at the top of the blue flame).
-When the magnesium begins to burn, do not look directly at it, as the light emitted can permanently damage your eyes.

Metals	Before	After
Magnesium	Metallic lustre	Bright White Light
Iron		Black
Copper	Bronze	Dark purple/Black

Observation

When the magnesium was held over the top of blue flame it started a bright white light while it was burning. Copper, when it started, was bronze then after it burned it turned Dark purple/Black.

Testing Hydrogen gas

Testing for Hydrogen Gas:

Aim:
To show the hydrogen gas is produced when a metal reacts with acid

Equipment:
A test tube, a boiling tube, Bunsen Burner, wooden splint, a bottle of acid, a piece of metal, safety glasses.

Method:
1. Light your Bunsen Burner
2. Add your sample of metal to your test tube. Add to mL of acid
3. Carefully invert the boiling tube above the test tube containing the metal and acid.
4. Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with gas.
5. When you think the test tube is full, your lab partner should light a wooden splint
6. Carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.


When the metal went in the acid it started to sizzle a bit forming smoke. After putting the other test tube over it nothing really was occurring. We lit the fire then put it in the test tube. Gas started forming on the rims of the test tube. After displaying that, there was a loud bang-like sound. That's when you know it works.

Science Expirement (Neutralisation)

Aim: To observe a neutralization reaction

Equipment: Test tube, Test tube rack, Ammonium Hydroxide, Sulfuric Acid, dropper or dropper battle,  Universal indicator solution

Method: Add approximately 1-2 mL of Ammonium Hydroxide and place the test tube into the test tube rack. Add
3-5 drops of Universal indicator solution. Using a dropper bottle, add Sulfuric acid drop by drop. Be careful because adding even a small amount of extra acid can mean you´ll miss the neutralisation.

Observations: Universal indicator turned blue when you put sodium carbonate solution. When you put acid it'll make some bubbles. When you add too much acid the colour changed to yellow, green and red.

How to Extract DNA from banna

DNA Extraction from a Banana

Aim: To successfully extract DNA out of a banana.

Equipment: 

1. 1/2 peeled ripe banana (you can also use strawberries or other fruit)
2. 1/2 cup hot water
3. 1 tsp salt
4. 1/2 tsp liquid dishwashing soap
5. resealable zip-top bag (quart size)
6. very cold rubbing alcohol (isopropyl alcohol) placed in the freezer ahead of time
7. coffee filter
8. narrow glass
9. wooden stirrer

Ingredients and Method

1. Mush the banana in the resealable bag for about a minute until all the lumps are gone and it almost looks like pudding.
2. Fill a cup with the hot water and salt.
3. Pour the saltwater mix into the bag. Close the bag and very gently squeeze and move the saltwater and banana mush together. Do this for 30 to 45 seconds.
4. Add the dishwashing soap into the bag and gently mix the contents. Try to avoid making too much foam.
5. Place the coffee filter in a clear glass cup, securing the top of the filter around the lip of the cup.
6. Pour the mix into the filter and let it sit until all of the liquid drips down into the cup.
7. Remove and discard the used coffee filter.
8. Tilt the glass and slowly add cold alcohol down the side of the cup. You want the alcohol to form a layer on top of the banana mix, staying separated, so be careful not to pour it too fast. Make a layer of alcohol that is 2.5-5cm (1-2in) thick.
9. After the alcohol layer is set up, wait for eight minutes. You may see some bubbles and cloudy material moving around in the alcohol. This is the DNA pieces clumping together.
10. Use the wooden stirrer to start poking the cloudy stuff in the alcohol layer. Spin the stirrer it in place to start gathering the cloudy stuff. When you are done, take a closer look at the stuff on the stirrer. You are looking at DNA!

Results: We successfully extract the DNA out of the banana. It looks like a jelly

Arthritis

Arthritis is an informal way of referring to joint pain or joint disease. There are more than 100 types of arthritis. People of all ages, sexes, and races can and do have arthritis. It affects the mobility of joints.
Common arthritis joint symptoms include swelling, pain, stiffness and decreased the range of motion. Symptoms may come and go. They can be mild, moderate or severe. 



Two common types of Arthritis: 
-Osteoarthritis (is a painful, degenerative joint disease that often involves the hips, knees, neck, lower back, )

-rheumatoid arthritis (a chronic progressive disease causing inflammation in the joints and resulting in painful deformity and immobility, especially in the fingers, wrists, feet, and ankles.)

Interesting fact: After years of treatment, some people who suffer from various forms of arthritis have turned to unusual natural treatments that come from snakes, bees, and ants.
