In our Bite Sized science we have been doing mini science experiments to learn the different parts of the scientific process. In each experiment we focused on a different skill that we will need for our own science fair projects.
Drink of density
In the drink of density our science focus was writing a hypothesis. We had to decide what we thought would happen when we layered different drinks into a glass and give reasons why we thought this.
"If the juice has more sugar it will float to the top because it has more sugar molecules" - Sophia
"If you add sugar to the water or juice it will be heavier and sink to the bottom" - Lia-Belle

Paperclip Peril
In this experiment we looked at the fact that a paper clip would sink if it was put into water but if it was placed on a certain type of paper we could push away the paper and the paper clip would remain floating. We discussed surface tension in terms of why this experiment works.
In this experiment we discussed the importance of variables in an experiment. We kept things simple and were only given the option of two things that we could possibly change.

Lava in a cup
In this experiment we poured water in a cup and then poured a layer of oil on top. We then sprinkled salt on top. The weight of the salt pulled the oil down through the water and then as the salt dissolved the oil floated back to the top. In the water we added food colouring so that we could see the movement more easily.
The focus of this experiment was 'observations'. We discussed how we had to look carefully at the experiment and note exactly what we saw and the changes that occurred.

Sparkly Snowflakes
In the experiment of growing borax crystals the focus was on method/procedure. The teachers demonstrated how the experiment worked and the class had to write down the specific measurements and steps so that they could create their own procedure to follow.
