Earth Layers Model | Science

 Earth Layers

Aim: To make a project that explains each layer. 

Method

• I will make half earth, which shows each layer of the earth. 
• I will make the base which is half earth.
• after I made the half earth, I will glue them together to make a solid base. 
• paint the crust witch is the land and the water of the earth, the mantle, the outer core, and the inner core. 

For this topic, I will be making the Earth layers. this will be describing what the earth inside will look like, and how the layers were ordered. I will also describe what each layer is made of. I made a replica of the earth layer by layer after layer of glue and newspaper. each layer of the earth is getting hotter and hotter, the mantle is the molten rocks due to the hotness of the core. the outer core is a full molten iron and nickel. 84% of the death is the mantle. we also reach this down when we dig 6 km down to reach the mantle.

Earth has been around for billions of years, and eventually, the earth will die in billions of more years. this earth won't last forever, 

 

Kiwi Fruit DNA | Science

 Aim: To get the DNA of the kiwi fruit.

Method:

1. Mush half a kiwi fruit in a ziplock bag with a splash f water and a small teaspoon of salt. 
2. Strain the solution through a cloth into a beaker.
3. Add a squirt of dishwashing liquid and stir. 
4. Pour into the test tube.
5. Place the test tube in a beaker filled with WARM water.
6. Slowly pour 5mL of methylated spirits down the side of the test tube. 

Picture: 

Discussion: Where did the DNA come from? the DNA came from the kiwi fruit we waited a few minutes to settle the mixture of salt and the much kiwi fruit.  after 1o minutes we added the 5mL of methylated spirits and wait for the reaction to happen we slowly can see the type of slime kind and that is the DNA of the kiwi Fruit. 

Conclusion: this actually works, I get to learn the DNA of the kiwi fruit. I've also known that DNA is in layer and layer before you can actually see the DNA properly. DNA is inside the nucleus. 

Wind Racer

Aim: To make the most efficient wind racer which would either go the furthest or looks the most creative. 

Method: 

• Gather all your equipment
• Set up your trolley and your bamboo stick, by placing the stick in the hole. 
• Cut a plastic bag into a partially large rectangle a size that would suit the stick. 
• Repeat with newspaper or paper. 
• Tape your first rectangle to the rod.
• Repeat with your other material. 
• After use sticks to create a structure for the sail, we used skewers but you can use another material. - Since we used a whole newspaper page, we stuck 2 skewers together from the ends. Making it longer. 
• Stick one pair at the top and another one at the bottom
• Depending on the size of your sail and rod place one or two pairs in the middle too. 
• After, make sure everything is secure by using tape in places that are weak. 
• Finally, decorate to make the appearance look more appealing. 

Equipment: Newspaper, plastic bag, tape, trolley, bamboo/metal rod, skewers.

Result: 

Discussion: Pull and friction were acting for the push and stop, but 2 more forces are pushing to each other to not fly the wind racer up or pulled down in the center of the earth. Gravity, and support.

Conclusion: I thought at first the this won't work at all, but when we tried it out is actually pretty cool to do, and it definitely works. 

Metals and Oxygen

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

Equipment: a piece of magnesium, bunsen burner, safety glasses metal scissor tongs.

Method

1. Light your Bunsen burner. 
2. Hold your magnesium in the scissor tongs. ensure you are holding onto this very tip of the magnesium. 
3. Place the other end magnesium into the Bunsen flame ( at the top of the blue flame ). 
4. When the magnesium begins to burn do not look directly at it, as it light emitted permanently damages your eyes.  

Result: I saw how these metals ignited into the light. I can only look at this for a couple of seconds or otherwise, this may permanently damage my eyes. 

Discussion: this happens because of the magnesium, when magnesium gets hot, the metal will turn into a hot light. it also because of the strong flame that we use. 

Conclution: yes, this works. this works as I think of it, I wouldn't change a thing about what we did in this experiment. this was a fun experiment I would like to do it again. 

Pop test

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

Equipment: A test tube, bunsen burner, wooden splint, a bottle of acid, a piece of metal, safety glasses. 

Method

• light you bunsen burner
• add your sample of metal t your tube. add 2 mL of acid. 
• carefully invert the boiling tube above the test tube containing the metal and acid (as shown in the diagram below). 

Result: the result is very surprising, it pops that's why the title of this experiment is the pop test. I saw how the pops happen. it is very cool it smokes after the pops happen. 

Discussion: it happens because of the hydrogen gas. this makes the pop sound because of the gas in it we trap it in the test tube so we can make the popping sound. 

Concussion:  yes, it did work. I wouldn't change anything in this experiment, I think that this experiment went really well. 

Indicators

 Aim: To make acid-base indicators using everyday substances.

Equipment: 

• Red cabbage
• Tea 
• Beetroot
• Turmeric
• Cranberry juice
• A beaker
• Water

Method:

Task One:

1. You now have five beakers, each containing a different indicator. 
2. Using a pipette, place 5 mL of the cabbage indicator into two test tubes.
3. Add 5 mL of HCI (Acid) to one test tube and 5 mL of NaOH (Alkali) to the other test tube.
4. Record the changes in the table below.
5. Clean the test tubes and repeat for the Beetroot, Tea, Cranberry, and Turmeric indicators.         

Discussion: For this experiment, we didn't use any burners. because our room is a classroom it's not a science room. so we found not to use any burners. but it still works and uses all of this to see if it's a base or an acid.

Conclusion: the experiment works. it was really fun, especially with my friends I'm working with. we were just having fun experimenting this indicator. 

PH test | Indicators

  Aim: To test the PH of a range of household chemicals.

Equipment: A variety of household chemicals, spotting tile, red litmus paper, blue litmus paper, Universal indicator solution, safety glasses, and a pipette.

Method: 

1. Add a few drops of each chemical to a spot on your spotting tile. If a substance is solid or powdered you will need to mix it with a few drops of water before testing it. 

2. Test the chemicals with litmus papers.

3. Test each chemical with a few drops of Universal indicator.

Result:

Discussion: We tested 4 types of chemicals. wich is spray and wipe, fabric softener, floor cleaner, vinegar.  These are the chemicals we use and tested their PH. this is the result that is shown. it showed different colors. we were making an indicator out of these chemicals. 

Conclusion: the Experiment works. the colores tell that the experiments are working. 

Model Atom

 Aim: To make a model atom 

Method: 

1. Chose an atom to make (between hydrogen and neon) 
2. Work out how many protons, neutrons, and electrons it has. 
3. Assign protons and neutrons to a particular color bred.
4. Get a ball of a blue-tac ad to stick the protons and neutrons to this to make your nucleus.
5. Cut out the appropriate electron shells and draw on the electrons with vivid. 
6. Connect the nucleus and electron shells with a piece of string. 
7. Create a label to go above the model so people know what you have created. 

Result: 

Discussion: In the periodic table I used N which means Nitrogen. the atomic mass of nitrogen is 7 and the mass number of nitrogen is 17, the amount of protons, electrons, and neutrons has the same number which is 7. I used 14 bids and stick them together with blue tac. and half of it has a different color than the other bids. in order to make atoms I have to use half electrons and half neutrons. N has no odor, is tasteless, and colorless.

• Nitrogen gas is inert.

Conclusion: my conclusion the model atom work than I expected. I would not do anything different things to the model.  

Circulatory system | Science

 Heart the heart is the part of the body that pumps blood to your body. one tube brings the blood then the other tube will bring the blood to your body and also pumps oxygen to your body. the common thing why people have a heart attack is because the heart stops pumping oxygen to your body. and veins are also connected to the heart. The atrium is the part of the heart that pumps blood to the heart and the ventricle is the part of the heart that takes the blood away from the heart. Aorta also takes the blood away from the heart and to the rest of the body. the vena cava is a large vein that carrying deoxygenated blood from head to heart.

Sport Science

 Why do road bikes have thin tire? 

they have thin tires because to lessen the pressure on the road and it also helps the biker to lighten the pedal in order to get faster. it made the bike faster because of the lightness and the less pressure on the ground. for decades bike tire has been adjusting to 19mm to 23 mm till 25 mm they try to see what is the right tire to be an aerodynamic, a 

why do mountain bikes have fat tires? 

they have fat tires because they need to balance into a rocky road if you have a thin tire to a mountain you have a big chance that you get injured.  and also one of the reasons mountain bikes have fat tires is because it contacts the grounds and less pressure it gives. 

tires are made out of rubber, this makes it perfect for a rocky surface but thin tires are smooth and its only capable of riding on the road.
