Social studies

In social studies we were looking at the biggest tsunami that has ever happened compared to some of the biggest buildings in the world.

This is the graph I made

Evaporation

We are learning about evaporation which basically is when water come to into the clouds when it gets drys. They are turning into a gas while they are doing this. 

Aim: To evaporate  copper sulfate to form a solute

Hypothesises: I think after we evaporate it it will turn to a dark blue solid

Equipment: Beacer, element, evaporation dish, copper solfate, heat proof mat, 

Method:
  1. Set up 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 the evaporating basin on top of the beaker. 

  5. Turn on the element to 3

  6. Heat the solution until 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.


Observation :

When it started to get warmer some bubbles started to form, then after a while some condensation and steam started to form.

Conclusion:
The solids in copper sulfate couldn't evaporate so they just turned into crystals on the side of the dish, and the liquid just evaporated into air.

Influences in relationships

In health we were learning about influences in relationships and what they can do to affect any kind of relationship. I made a slideshow to tell you guys a little about it.

Dilution experiment

In science on Monday we did a experiment to less dilute potasium permaaganate in water.

The Aim of this experiment was to see how the colours get less and less vibrant as it gets less dilute.

We did this by first putting 10 ml of water in one of the test tubes and 5 ml of water in all the other ones. The teacher put potasium pernaagante in the test tude with 10 ml of water, and then we keep taking 5 ml out of the tubes we put the solution in to make it less and less concentrated. 

The equipment we had was 5 or 6 test tubes, a measuring thing and a squirting thing.

I think it went pretty well and the teacher accidentally messed up on some but ours she didn't mess up and was what it was supposed to look like. When we first started the 1st test tube was pretty concentrated because there was a lot more potasium permaagante, and the last one was the least concentrated because there was more water. It was all different shades of purple, the first one was the most purple because it was the most concentrated and the last one was the lightest because it was the least concentrated.
