Filtration Experiment

Filtration Experiment

In hurumanu 3 today we are going to be doing a Filtration Experiment, we have been learning about particles and today we are going to try and filter them.

Hypothesis: What do you think will happen

Aim: To separate a solution from a precipitate (precipitate is the name for a solid that forms in a liquid during a chemical reaction)

Equipment:
Sodium carbonate

Copper sulfate

Conical flask

Stirring Rod

200mL Beaker

Funnel

Filter paper

Hypothesis: What do you think will happen?
I don't think that much will happen I think it will just stay blue but im really hoping something interesting 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:
When we poured the liquids into the funnel it was a very ultra blue type colour but when it started filtering it turned into a clear colour which was the sodium carbonate we mixed into the copper sulfate , on the filter paper there was a blue residue that we could see.
All of the blue colour got filtered out and left behind a clear liquid.

Hurumanu- Water cycle

How a water cycle works
For science this term we are learning about fossil fuels and climate change. We are doing this experiment where we are seeing what happens when you inclose water in a Ziplock bag and leave it in the sun. The steps and methods below explain what I think is going to happen and what we did.

Title

How a water cycle works 

Purpose

To find out how the water cycle works 

Materials

-Large ziplock bag x 2
-Black vivid x1
- 1 cup of water
- Blue food dye
- Baking soda 
-Litmus paper
-Double-sided tape

Steps

(Experiment 1)

  1. Grab the large Ziploc bag
  2. Draw the water cycle on the large Ziploc bag (in vivid)
  3. Show Mr palmer the drawing.
  4. Mr palmer adds 1 cup of water into the large Ziploc bag
  5. Then he adds 2 drops of blue food dye 
  6. And then you stick it on the window where the most sun gets through and wait

(Experiment 2)

  1. Repeat step 1 and 2 of the first experiment.
  2. Show Mr palmer your drawing on the ziplock bag
  3. Mr palmer will then add 1 cup of water into the Ziploc bag
  4. Then he will add 2 drops of blue dye
  5. And then 1 tsp of baking soda 
  6. Stick your double-sided tape on and then stick it on the window and wait.

Conclusion

Experiment 1

I think the outcome of this experiment will be...
Not so drastic as the 2nd experiment I think the water will either evaporate or collect water.
What actually happened
Experiment 2
I think the outcome of this experiment will be more interesting and have a lot more outcomes than the first mainly because it has baking soda and is enclosed in a Ziploc bag, therefore, creating more carbon dioxide then experiment 1  and carbon dioxide is a fossil fuel.
