Metal Reaction

Testing for Hydrogen Gas, Sound of POP test.

The aim is to make a metal oxide and observe the difference and properties of the product compared to the reactants.

1. MEtal + Acid

• Equation 

Metal + Acid = Metal salt + Hydrogen

Magnesium + Sulfuric Acid  = Magnesium sulfate

•  Method 

1. Put 2ml of sulfuric acid and a piece of magnesium metal inside the test tube.

2. Boiling tube inverted to collect any of the gas that is produced.

3. light up a splint and hold the boiling tube that has gas inside 

•  Conclusion

When I inserted the flaming splint inside the boiling test tube while the Hydrogen gas was inside, It made a pop sound so it means that there oxygen that is trapped in a boiling tube. 

Testing Out FOr the Presence of oxygen.

Aim: To carry out the test for the presence of gas (O2)  

Equipment: A pea-sized amount of manganese dioxide (MnO2), Boingtube, bottle hydrogen peroxide (H2O2), Woden splint, Bunsen burner, test tube rack, and don't forget a safety glasses.

Method

1. Add manganese dioxide in a boiling tube. 

2. add 2 ml of hydrogen peroxide.

3. lit up ur splint with a bunsen burner.

4. Blow up ur burning splint and insert the glowing embers into the mouth of the boiling tube.

5. You will see the tip of the splint will get reignite and it's bery bery aswesome!!!.

Thae Conclusion:

When the acid was added into the boiling tube I can see a bubble of gas that was released.

Acid Rain experiment

 Hello again my precious prends!!

So today my class is gonna experiment with something but I do not know yet, but I think we're experimenting with something about acids. So here we go guys, but i write about the acid rain first.

What is acid rain?

Acid rain, or acid deposition, is a broad term that includes any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms. This can include rain, snow, fog, hail or even dust that is acidic.

What is our Aim????

Our aim is to observe the effects of acid.  "Aaah ok ok".

Hypothesis.

Petal, Calcium Carbonate, Apple, Universal indicator, Bromothymol Blue.

Method.

In a Petri dish place items around the edge. Wet dry ingredients with a drop of water. In the middle, put a weight bout.

Observation

The Universal indicator changed its color to red, Bromothymol blue to yellow, and Petal to lighter clour of its color. and the only color that didn't change were calcium carbonate and apple.

Atomic Science: Periodic Table

 Hello guys, today I am writing something about the periodic table that i learned in science.  

What does the periodic table show us?

• Mass Number

• Element

• Atomic

• Different column

• Different rows

• Features of the elements.

Alkali metals

Transition metals

Gases

The Periodic Table shows us the mass numbers on each element / atomic. On the Periodic table, there are different columns and rows on each. On each row, there are different features of the elements (Alkali metals, Transition metals, and Gases)

Alkali metals: Alkali metals react with any other element on the periodic table. Alkali metals have an unstable outer shell, so… The Alkali metals consist to get rid of their electrons by sharing. And that is why they react and explode because they have reacted.

What are alkali metals 

• 1st column

• Electron in outer shells

• What does it mean?

Separating a mixture using distillation

Separating a mixture using distillation

Aim: to separate a solute from a solvent in a solution using distillation

equipment:
1. coke zero
2. conical flask
3. delivery tube
4. bung
5. element
6. retort stand
7. ice to cool up the gas
8. boiling tube

method:
1. set up the equipment as shown on the diagrams
2. add the conical flask 50 ml of coke zero
3. put the flask on the element and turn on the element.


discussion:
we used a conical flask to hold our solution of coke, then we boiled it using an element with the coke in the flask. and after the coke zero evaporated into a gas we used the delivery tube to transfer the gas to a boiling tube, then we put the beaker that has ice inside, under the boiling tube to cool up the heated gas to a liquid/Condenses. after the coke zero evaporated, the sugar was left behind inside the flask.

Looking inside rat's body, Science experiment

this weak on a science experiment, we look at the inside of the dead rat. We were excited experimenting with a dead rat and some others were not and they were discus and they were not even want to participate with the experiment.

The equipment we used was.
Tweezers to move the organ around.
scissors is to cut thru the bone and stuff.
scalpel for slicing the skin open of the rat.

Our teacher gathered us showed us how to cut thru the rat's body and explained us how to use the equipment she was using, some others was discussed while the body of the the rat was sliced up thru the body. When she was done showing and explaining us the body of the rat, our teacher split us up into 3 groups and gave us a death rat.

When it is our time to do some experiment, we opened the body of the rat we were looking and finding the Liver, intestines, heart, lungs, stomach, and more. Were going to see how lots of organ reacted to the rat's body, and our teacher were explained fun facts about the organs.

Testing For Nutrients

Testing For The Nutrients 

Hypothesis: I think bread will be a complex sugar, I think the egg will be a Protein, I think the glucose/sugar/lolly will be a simple sugar, I think the apple will be a simple sugar, I think the milk will be a complex sugar.

Aim: To test if a sample of food contains protein.

Method & Result: 1&2&3
In 1 test, We tested Apple, Bread, and potato on two drops of Iodine and it just turned black because the Iodine was brown and brown means simple sugar and the black means complex sugar. Next, we tested Milk, Egg yolk, and sugar and we put two drops of Iodine and it did not turn into black so it means they all simple energy and it is fast to run out of energy. In test 3, we tested the 6 of the food we tested before and we put 5 drops of Benedict's reagent and then we boiled them, there was only 1 of testing food that did not change its color, It was bread I think that is because the bread is a complex sugar and the apple, egg yolk, milk, glucose was a positive and I don't know about the potato because its kinda turn into greeny ish. In test 3 we tried 5 drops of Sodium Hydroxide/NaOH(aq) and Copper(II) Sulfate/CuSO4(aq) on 6 of the food and 4 turned into purple wich is Glucose/sugar, egg, bread, and milk, then App and the potato didn't turn into purple, so in my belief, the purple means its complex sugar and the apple and potato are simple sugar.

Equipment:

Bread

Egg

Glucose/sugar/lolly

Apple

Milk

Potato

Discussion:

Protein	Complex	Food	Simple
no	no	Apple	yes
no	yes	Potato	no
yes	yes	Bread	no
yes	yes	Egg yolk	no
yes	no	Milk	yes
yes	no	Glucose/sugar	yes

Conclusion
 I have learned a lot.  I've learned how long it takes for stylophone to rot it takes thousands of years so it means that it takes the longest to break down.  Banana is also the easiest to rot out of the four it had already gone mouldy.  I'd like to finish off with I would like to do this again.
