Scientific Diagrams
What equipment is used to heat substances?
Bunsen burner
What variable do you change in an experiment?
Independent variable
Pushing a door is an example of what type of force?
Direct force
What area around a magnet is affected by its force?
Magnetic field
What force makes everything fall towards the ground?
Gravity
When drawing a diagram, should you use shading?
No
What variable do you measure in an experiment?
Dependent variable
What is the name of an indirect force that causes objects to fall?
Gravity
What happens when two north poles of magnets are placed close together?
They repel each other
Do you weigh the same on Earth and the Moon?
No, your weight changes because gravity is different
Name an item used to measure liquid volume.
Measuring cylinder
Name an example of a controlled variable.
Type of plant or amount of water
True or False: Static electricity is an indirect force.
True
Name a material that is magnetic.
Iron Cobalt Nickel
What stays the same everywhere: mass or weight?
Mass
Why is it important to label all parts of a scientific diagram?
So the diagram is clear and others can understand or repeat the experiment
In an experiment testing water temperature and sugar dissolving, what is the dependent variable?
The speed the sugar cube dissolves
Give an example of a direct force.
Kicking a ball
What is an electric field?
The area around charged objects where electric forces act
What unit is used to measure weight?
Newtons
What tool would you use to ensure straight lines in a diagram?
Ruler
Why do scientists use controlled variables in experiments?
To make sure results are fair and only the independent variable affects the outcome
Explain the difference between direct and indirect forces.
Direct forces require physical contact, indirect forces do not
How do field lines behave around a magnet?
They go from north to south outside the magnet
Explain how weight and mass are different.
Mass is the amount of matter; weight is the force of gravity on that mass
