Working Scientifically Flashcards
Identify the parts of a Bunsen Burner and record the steps for lighting it
Base, collar, air hole, gas hose, cone of unburnt gas, flame
Attach the gas hose, make sure the air hole is closed
Light a match
Turn on gas tap
Put the match above the barrel
Blow or shake out match
Identify observations and make inferences form these observations
An observation is what you can see, hear, taste, smell and touch
An inference is what you can infer from the observation
E.g.
Everyone is packing up
It must be nearing the end of the lesson
Identify independent, dependent and controlled variables for a given investigation.
An independent variable is what has changed, only one can be changed or the experiment will not be valid, think about it how will be changed and what equipment will be used. A dependent variable is what is measured, think about how it is measured and what you will measure it with/in. A controlled or constant variable is what is kept the same it NEEDS to be kept the same or else it will not be a fair test.
Write an aim, method and conclusion using given scientific information
An Aim should be not too long, and just mention what you want to achieve in the experiment . The hypothesis should be your prediction as to what is going to happen, it should be clear and short it is an inference based on what you already know. The method is a detailed list of what you did in the experiment. You must include quantities you used and the exact order the steps were performed, a diagram is useful. Conclusion should be short and relate to the purpose, it should also relate to the purpose and hypothesis
Use scientific knowledge to suggest improvements to an investigation.
Using inferences and common knowledge to make changes to the INDEPENDENT VARIABLE, informed changes- not guesswork. Informed decisions based on prior knowledge.
