Particle Theory & Diffusion

Hi Kumusta, This week our focus for science are Particle Theory and Diffusion. Particles are small unit of matter

-Aim: Investigate if particles diffuse faster in hot or cold water.

-Hypothesis: I think it will diffuse faster in hot water than cold Water.

-Result: My hypothesis were right, The hot water diffused first.

-Discussion It happened because heat/hot water gives energy to the particles to move faster.

  Bottom one is the hot water.
 

Where the Black Death Fits in to History

Hi Kumusta, last week we were ask to make a timeline about plagues and sickness that roam the world and this is my work

Super Hero

Arts Kete

In the last few weeks we did our Arts Kete, I choose lazer cutting because the one I want was already full. In my arts kete we designed the thing we want to lazer cut in a paper, others did Maori designs, and cool patterns and  my first Idea was a clock with the purpose word in it then I started to draw it and I came up with another Idea and it was a wood with the word 'Live With Purpose'. Few days later When we did our final design I thought of cutting the wood in half and cut out the P,U,R letters then place it in a paper and then in the other half ill cut out POSE letters in the wood then ill take the wood and place it in the paper.

Evaporation Experiment

Kumusta, In the past few lesson in our science we've been learning evaporation and today were about to do a experiment about it.

Aim: To evaporate Copper Sulfate (Blue Liquid) to separate the mixture.

Hypothesis: I think that there will blue stuff left in the 

Equipment: Copper sulfate solution, 250ml Beaker, heat proof mat, evaporating basin, element.

Method: 

1. Set up the element.
2. Add 100ml of hot water to the beaker and place on the element.
3. Add copper sulfate to the evaporating basin until it is quarter full.
4. Carefully, place the evaporating basin on the top of the beaker.
5. Turn the element to 8.
6. Heat the solution most of the solvent has been evaporated and crystals of solute are forming.
7. Turn off the element-careful not to touch as will be hot for a long time.

Conclusion: I can see that my hypothesis is correct because it left with blue crystals on the evaporating dish.
