Temperature
What is temperature?
Measure of how hot or cold something is.
What is mass?
Measurement of the amount of matter in an object.
What is magnetism?
A force where certain metals attract and repel
What determines if something sinks or floats?
Density of the object.
Name three physical properties of matter.
Mass, state of matter, temperature, magnetism, sink and float.
How do we measure temperature?
Using a thermometer.
How is mass measured?
Using a balance scale pan balance or triple beam balance
What do we call it when two magnets push away from each other.
Repel
Why do some objects float in water while others sink?
Due to the difference in density between the object and the water.
How does temperature affect the state of matter?
It changes; for example, water turns to ice below 0°C and to water vapor above 100°C.
What scale do we use to measures temperature in science?
Celsius
What is the difference between mass and weight?
Mass is a measure of matter; weight is the force exerted by gravity on that matter.
What positions do the poles on a magnet need to be in to attract.
Opposite poles attract. North and South pointing towards each other
If you throw seven wood pencils and four metal washers in a swimming pool what will happen?
The seven wooden pencils will float and the three metal washers will sink.
What property measures how much matter is in an object?
Mass.
How do different temperatures affect the state of matter of water?
The water will freeze at lower temperatures and boil at higher temperatures. It will remain a liquid at medium temperatures.
How does gravity affect mass?
Gravity does not affect mass, but it affects weight.
Explain how the different magnetic poles interact?
Opposite poles attract, like poles repel.
How can density determine whether an object will sink or float?
If the density of the object is greater than the density of the fluid, it will sink. If less, it will float.
What are physical properties?
Physical properties are properties that can be observed without changing the composition of the substance.
How does temperature affect the speed of molecules?
Higher temperatures increase molecular speed.
Which one has the most mass.
300 grams of cotton
300 grams of grass
Or 300 grams of bricks
They are all equal in mass.
What tool do we use to harness the Earth’s magnetism be used in navigation?
Compasses point toward the magnetic north, aiding in navigation.
A pencil, a tree, and a toothpick are thrown in a river. Which one will sink first.
None of the will sink because they are made of wood and wood is less dense than water.
Explain how magnetism is a physical property of matter.
Magnetism is a physical property that explains why some metals attract and repel.
