Testing for the Presence of Oxygen

 Aim: To carry out a test for the presence of oxygen gas.

Equipment: A pea-sized amount of manganese dioxide, boiling tube, bottle of hydrogen peroxide, safety glasses, wooden splint, Bunsen burner and a test tube rack.

Method:

1.  Light your Bunsen burner.

2.  Add the manganese dioxide to the boiling tube and place it in your test tube rack.

3.  Add 2ml of hydrogen peroxide.

4. Light  a splint and let it burn for a while.

5. Blow the splint out and insert the glowing embers into the mouth of the boiling tube.



Observation: When we inserted the splint embers into the boiling tube it re-light the splint. It re-light because there was oxygen being produced by hydrogen peroxide and manganese peroxide. 





Trashing our Planet | Social Studies

 Today I am going to make a new blog-post about what we are learning in my social studies. So far we have been learning about the ocean plastic pollution, we looked at Happy broadcast which is a news channel that only has positive news. We watched a few videos about people telling us what is happening in the ocean and we answered some questions about it. 

What does plastic pollution do to our ocean? Plastics are bringing more problems to the ocean and for the marine life, plastics take 500 or more years to break down. Also plastics breakdown to small-tiny pieces called micro-plastics. Micro plastics is bad and dangerous because of the chemicals in it and if it is ingested by a marine animals it can block digestive tracts.


How can we help?/What is something you could do to reduce what goes in your red bins? To reduce what goes in your red bins you should put the right trash in the right bins, recyclable items should go to yellow bin, food compost should go in the green bin and non recyclable or organic goes in the red bin.

Metals and Oxygen

 Last week we did we did another experiment it was about making a metal oxide and Today I will be talking about it.

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

Equipment: A piece of magnesium, Bunsen burner, safety glasses and metal scissor tongs.

Method:

1. Light your Bunsen burner.

2. Hold your piece of magnesium in the scissor tongs. Ensure you are holding onto the very tip of the              magnesium.

3.  Place the other end of the 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 the light emitted can permanently           damage your eyes.

Observations: The magnesium got very bright when it was burning and became like a powder/ash when it stopped.

Metal Reaction

 Today in our Science class we did an experiment about metal and how it reacts to acid. 

Equipment:

  • Test tube
  • Boiling tube
  • Piece of Metal / Magnesium
  • Acid 
  • Wooden splint 
  • Bunsen Burner 
The first thing we did was to put 2ml of acid in our test tube, then we dropped a piece of magnesium in the test tube ad covered it with the boiling tube to trap the gas being produced. After a minute we burned our wooden splint and took the boiling tube filled with gas and we sticked the burning splint inside and it pop.

Acid Rain Expirement

 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 will be to observe effects of Acid Rain.

Hypothesis

Petal, Calcium carbonate, Apple, Universal Indicator, Bromothymol Blue.

Method: 

In a petri dish place items around the edge. Wet dry ingredients with drop of water. in the middle put a weight boat. 

Add a spatula of Sodium sulfate to weight boat, and 5 drops of Sulfuric Acid.

Observation:

The Bromothymol turned yellow, the Universal Indicator turned red, some part of Calcium Carbonate were wet, I'm not sure what happened to the petal and but it kinda turned into a darker colour.
