Chemical fizz

WALHT: understand the areas of the what our senses from constiuents.

It was the year eight’s eighth week in Technicraft (science class), it had begun with 5 substances; Icing Sugar, Sodium Carbonate, Vita fresh, Citric Acid and Tartaric acid, following with a saucer.

Paper towels were provided for each person in able to observe the senses (of the state, texture, smell, colour and taste) from the substances. With these levels of substances and senses left the year eights thinking in a whole new different level of understanding, from which of a chemical reaction would the substances create once combined? There wouldn’t have been a chemical reaction as a state of a liquid hasn’t been added.

When H2O combines with a series of solid (powder) combined together it creates a chemical reaction which activates gas pockets.

States of matter

WALHT: Observe and discuss the relation when 2 states of matter when combined.

Cornstarch is a substance which has a solid state of matter. Water is a substance which has a liquid state of matter and mixing these two substances creates a colloid which has a combination of 2-3 states of matter.

Materials:

50mls Cornstarch

15mls Water

Knife

Container

Method:

1. In a shallow clear container add the cornstarch
2. Add the water bit by bit and stir while doing the process.
3. Once done, experiment on this solution and see the changes from the state of matter.

The reaction between the substance of cornflour and water mixed together created  a solution that has the ability to have strong viscosity when strong pressure is applied to the colloid and as when you apply a gentle pressure to the liquid it instantly forms its state to a liquid.
