Term
What is the formula for finding the volume of a regular shape?
Definition
Volume = length X width X height

288 cm3
Term
Name the three most common states of matter. Give an example of each.
Definition
Solid – table, Liquid – water, Gas - oxygen
Term
Describe the movement of molecules in each state of matter.
Definition
Solid – vibrate or shake in place
Liquid – can move around and slide passed each other
Gas – can move about very freely
Term
What is an atom?
Definition
The smallest, or most basic, unit of matter

Contains only one type of atom
Term
What is a compound? Give at least one example.
Definition
Consists of two or more types of atoms bonded together. Example – salt
Term
What is a mixture? Give at least one example.
Definition
A combination of different things that stay the same individual thing when mixed and can be separated physically. Example: fruit salad
Term
Name 3 ways to separate a mixture.
Definition
Magnets, evaporation, filtering
Term
Describe the particle arrangement and movement in a solid.
Definition
Tightly packed together, constant motion by twisting and vibrating.
Term
Describe the particle arrangement and movement in a liquid.
Definition
Spread out and move constantly more freely than a solid, but not as much as a gas.
Term
Describe the particle arrangement and movement in a gas.
Definition
Spread far apart, move constantly and the most freely of all states of matter.
Term
What are physical changes? Give two examples.
Definition
A change in any physical property of a substance, not the substance itself. Examples: shaping a piece of clay, or painting a house
Term
What are chemical changes? Give two examples.
Definition
A change of one substance into another. Examples: burning wood or iron rusting
Term
What is an insulator? Give an example.
Definition
Material that does NOT allow electricity to flow easily. Rubber.
Term
What is a Conductor? Give an example.
Definition
Material that does allow electricity to flow easily. Metal
Term
What is the difference between current electricity and static electricity?
Definition
Current electricity is a continuous flow of electric charge while static electricity is a buildup of electric charge.
Term
In a series circuit, if one appliance stops working, what will happen to the other appliances in the same circuit?
Definition
They will stop working because they share the same path to the voltage source.
Term
In a parallel circuit, if one appliance stops working, what will happen to the other appliances in the same circuit?
Definition
The other items will still work because each has its own path to the voltage source.
Term
What is the purpose of a circuit breaker when the circuit is overloaded?
Definition
To open the circuit and turn off the power.
Term
List and describe the four basic characteristics of living things.
Definition
1. organization – have cells that allow them to get energy and to move.
2. growth – consume food to get larger
3. reproduction – form other organisms like themselves, DNA is copied and passed on to offspring
4. response to their environment – react to light, temperature and touch
Term
Define symbiosis. Describe the three different types of symbiosis.
Definition
A close relationship between 2 different species that live close together
1. Mutualism – both species benefit
2. commensalism – one species benefits, the other is not affected
3. parasitism – one species benefits, the other species is harmed.
Term
How are organisms classified?
Definition
kingdoms
Term
21. Most scientists consider viruses to be non-living. Explain why. What do they have in common with bacteria?
Definition
They do not respond to their environment, don’t grow, and don’t take in energy. They have DNA like bacteria do.
Term
What are bacteria? List the defining characteristics.
Definition
Simplest form of life. Single celled, no nuclei
Term
Define cell.
Definition
Smallest unit of life that is able to perform the basic functions of life.
Term
Compare and contrast plant cells and animal cells.
Definition
Compare – both have nuclei, cell membrane, mitochondria
Contrast – plant cell has chloroplasts, animal cell does not. Plant cell has cell wall, animal cell does not. Plant cell is rectangular shape, animal cell is circular or irregular shaped
Term
Explain photosynthesis.
Definition
Process in which producers use energy from the sun to make sugar.
Term
Explain cellular respiration.
Definition
Process in which cells use oxygen to release stored energy.
Term
What 2 factors make up an ecosystem?
Definition
Abiotic factors - non living
Biotic factors– living thing
Term
What is a habitat?
Definition
The physical location where plants and animals live.
Term
Explain the difference between deciduous and coniferous trees.
Definition
Deciduous – broad leaves, drop leaves in winter time, dormant in winter time
Coniferous – needle like leaves, keep leaves in winter time
Term
Give 2 examples of animal adaptations.
Definition
Thick fur for cold climates
Skin/fur color for camouflage
Term
Explain how living things cooperate and compete.
Definition
Cooperate – working together to benefit all, ants bring food to the nest
Competition - a struggle for limited resources, hyenas and vultures fighting over remains of dead animal for food.
Term
What is a producer?
Definition
An organism that makes its own energy using sunlight.
Term
What is a consumer? Explain the 3 levels.
Definition
An organism that gets energy from eating other living things
Primary – first link between producers and the rest of the consumers
Secondary – eat primary consumers
Tertiary - eat secondary consumers
Term
Explain the role of decomposers.
Definition
An organism that breaks down dead organic matter
Term
What is an energy pyramid?
Definition
The amount of energy decreases as you move up the pyramid
Term
Compare and contrast food chains and food webs.
Definition
Compare – both show feeding relationships, both have producers and consumers
Contrast – food chain only show a single chain of consumers, and food web is many overlapping food chains.
Term
What would happen if an organism were removed from its ecosystem?
Definition
Other organisms that rely on it for food could die out.
Term
What is a pollutant?
Definition
Substances that are harmful to the environment.
Term
Explain the difference between erosion and weathering.
