Properties of Matter
The comparison of density when an object is placed in a liquid.
What is relative density?
Needed to start or stop the motion of an object or change its direction of motion.
What is force?

What are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune?
Mix of all living and non-living things.
What is an ecosystem?
3 types of Landforms
What is delta, sand dune, and canyon?
The ability to carry thermal or electrical energy.
What is a conductor?
Reflection.
What is light bouncing off a shiny surface and returns at the same speed and angle?
Fossil fuel.
What is high energy material created from the remains of buried plants and animals?
Describes how energy is passed from one organism to another.
What is a food chain?
How Earth rotates.
What is on its axis?
The ability to be attracted, or pulled, to magnets.
What is magnetism?
