Filtration Experiment

Today in hurumanu 3, we were doing chemistry we did a filtration experiment.

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:I think everything is going to go through the filter.

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: After we put it in the funnel, it went through and turned clear. 

 

Health- Relationships

In class we have been talking about relationships. We were talking about " Online relationships are not as important as real life relationships." We had to write a paragraph on what we think of this statement. Here is mine...

Some people may think online relationships are not as important as real life relationships. I honestly think they are the same, you just don't see them. I think that if you like them then you should still talk to them even if it is online. You should make sure they are who they say they are though, but if you trust them then its a healthy relationship. On the other hand, some people think there not as important as real life relationships, which is fine everyone has there own opinion. In conclusion, I think they are both important. 

Sustainability

In Sewing we had to find things we could make over the next few weeks. Here are my ideas....


Memory box- Paint the outside of the box. Then use scrap material to write something on top. 

Mat- Use wool to make pompoms, then put all the pompoms together to make a mat.
