Filtration Experiment

Today in Hurumanu 3 we are doing Filtration Experiment for chemistry. Aim: To Separate a solution from a precipitate (precipitate is the name for a solid that forms in a liquid during a chemical reaction).

Hypothesis: what do you think will happen...

Method: 

1. Pour approximately 50mL of copper sulfate solution into a beaker.

2. Add the same volume of sodium carbonate solution. A reaction will happen, you should see a cloudy blue precipitate form. Called copper carbonate. 

3. Watch demo then fold filter paper to fit inside the funnel

4. Place the funnel with the filter paper inside of it, into the mouth of a conical flask. 

5. Stir the mixture in the beaker, then carefully pour it into the funnel. 

6. Observe what happened.

Observations and Discussion: what you saw happen and why do you think it happened.

The copper sulfate + Sodium sulfate were clear but then when you mixed them together it made to foggie and you couldn´t see through it anymore.

Serial Dilution: repeated divulting (making it weaker)

water + potassium permanganate - mixture/solution.

1.Water 10 mL 2. 5mL 3. 5mL 4. 5mL 5. 5mL 6. 5mL

         + 

   KMn04

Most concentrated.                 Least concentrated.

Most KMn04.                         Most Water

least water.                             least KMn04

least Dilute.                            Most Dilute.

The biggest one had the most purple and had the most in it, you had to put 5mL in each one so it can be all even. Number 6 was the lightest because it was the last to go in and that you couldn't take any of the purple stuff that was in the the biggest one from the start, it had to be all even so at the end they could be the same hight.

Well being!!!

       Online relationships are not as important                      as real life relationships:

In class we were talking about is " Online relationships are not as important as real life relationships, why? probably because in real life relationship, you actually get to spend time with your boyfriend/girlfriend!. You get to have them really good moments with them we do spend time with them. In my opinion I reckon that real life relationship is important!. Some other reasons why real life relationship are way important then online relationships, is that you wanna try spend as much time with them because they will most likely know that your still in love with them and wanna be there for them 24/7.

Online relationship I reckon isn´t really a good thing because you might be living far away from them (long distance relationship) You won´t be able to spend as much time with them, it might be a stranger who you´ve never met before. Their could probably be cat fishing you or something. They could be lying about who they really are.

But when I have a think about, I reckon that online relationship could be kind of important because what if you´ve been with your boyfriend/girlfriend for ages and you would need to go online to use Facebook, Instagram and Snapchat, You would at least need to contact them by using online apps. 

Some people might have different opinions about online relationships are not as important as real life relationships.

The Great bubble.

Kia ora everyone today at period 2, we had to do this activity with the class, we had to choose some colours first, I choosed, blue and red because they were my favourite colour. After we got to choose our colours we had to answer the question that our colour was. I decided to choose red because we had to choose one colour for our choice.

My question was, (what was something funny that happened in lock down) something funny that happened in lock down was playing WWE 2k16 and I made my character really funny and ugly. After the rest of the class explained their colours, we had to design them with these thingy. Here's what I made...

That's what we had to make for last period. I hope you enjoyed the blog. Please leave a positive, helpful and a thoughtful comment down below.
