Matter and Energy
What is the term for "the amount of matter in an object"?

What is the force that pulls objects down?
Gravity
What is an ecosystem?
A community of living organisms and their interactions with the environment (Abiotic and Biotic)
What causes day and night on Earth?
The rotation of the Earth on its axis.
What is matter?
Anything that has mass and takes up space.
Name a property that can be used to describe matter.
"Color, shape, mass, density, magnetic, state of matter"
In an experiment testing magnetism, how can you determine which materials are magnetic?
Use a magnet to see which materials are attracted to it.
What do plants need to grow?
Sunlight, water, air, and nutrients from soil.
Why does the Sun appear to move across the sky?
Due to the rotation of the Earth.
What is a conductor?
Something that ALLOWS the flow of heat and electricity through it.
What happens when a solid is heated?
Can be melted into a liquid
What happens to the speed of an object when friction is applied?

How do animals adapt to their environments?
They develop traits that help them survive in their specific habitats.
How does the Earth's revolution affect the seasons?
The tilt of the Earth's axis during its revolution around the Sun causes seasonal changes (more or less heat from the sun).

How do you separate a mixture of sand and water?
Dissolve the salt into water, filter out the sand, then evaporate the water to get the salt back.
How can you investigate the strength of different magnets?
Measure how many paperclips each magnet can hold at a distance.
A sequence showing how energy and nutrients flow from one organism to another. Producer, to Consumer. Grass to rabbit to fox.
Describe how the position of the Sun affects shadows throughout the day.
Shadows are longest in the morning and evening when the Sun is low in the sky and shortest at noon when the Sun is highest.
