Working Scientifically
What does a rating of 1 on the HAZPAK ranking chart mean?
It is very likely that there will be a severe injury or illness from the hazard.
How are the particles in a solid arranged?
Tightly packed together.
What is density defined as?
What part of the bunsen burner should you hold when moving it around the room?
The base
What are animals called that only eat plants?
Herbivores
What branch of Science is "The study of forces, movement and energy"?
Physics
Yes, unless the temperature is at absolute zero.
Water has a density of 1. Honey has a density of 1.36. If we pour both liquids into a measuring cylinder, what one would be on top?
Water
What are the two types of flames the Bunsen Burner can have?
Safety (yellow) flame and working (blue) flame
Mercury
What is an Inference?
A possible explanation for an observation.
What are particles described as in the particle model?
They are small, hard, round balls called particles.
How can I measure the volume of a mass using a measuring cylinder?
Putting it into the water and measuring the displacement of the water. This will equal the volume.
What is the name of the part on the bunsen burner that swivels to cover the air hole?
Collar
What is the order of the planets in the Solar System starting with the planet closest to the Sun?
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
An example of qualitative data would be..
Descriptive, can be observed but not measured.
E.g. colour, smell, taste
What is the change of state called when a liquid changes to a gas?
Evaporation
How does a hot air balloon float?
The heat in the balloon causes the particles to move further away from each other, making it less dense. The gas in the balloon is less dense than the air around it, so it will float.
When lighting a bunsen burner, do you light the match or turn the gas on first?
Light the match.
What are the colours of a rainbow?
Red, Orange, Yellow, Green, Blue, Indigo, Violet
What are the headings that should be in a scientific report?
Title, Aim, Hypothesis, Materials, Method, Results, Discussion, Conclusion
Condensation
What is the formula for density?
Density = mass/volume
What is the name of the man who invented the Bunsen Burner?
Robert Bunsen
