Chantelle asked “Why is gold so hard to find?”
Shelby asked “Why is gold so heavy and hard to pick up ?”
Mary asked “Why is gold so expensive?”
Chantelle, Shelby and Mary some great questions , thank you. But are they science questions? Lets look at what a science question is.
A science question is a question that may lead to an idea and help us in answering (or figuring out) the reason for some observation.
For example ‘Why is gold so heavy?” …so firstly let us look at what gold is. Gold is a solid – Is it a rock? Is it wood? Is it plastic? Is it a metal? ……it seems to fit into the group called metals (it’s cold to the touch, it’s solid, it can be scratched, it’s shiny, it’s heavy) it’s a metal. So Shelby’s second question is a good science question.
Is it heavier than other metals? It doesn’t seem to be heavier than other metals but how do I test this? Fair tests are important in science investigations. Being fair I compared my gold with with metals of comparable size? It is heavier, why? Maybe the bits which make up the gold are heavier than the bits that make up other metals?
Chantelle. I think gold is quite easy to find compared to other metals. Lots of other metals, iron, silver, copper and aluminium exist as minerals so they are quite difficult to find. What is a mineral? Look at the following page.
