Mention 3 characteristics of a Pseudoscience claim.
1. Does not follow the scientific method. 2. Lacks supporting evidence 3. Cannot be reliable tested.
100
What are the 4 states of matter?
Solid, Liquid, Gas, and Plasma

100
What are isotopes?
They are atoms that have the same number of protons but a different number of neutrons.
100
What's the difference between homogeneous and heterogeneous mixture?
A homogeneous mixture has the same appearance through out and a heterogeneous mixture has visible different substances.
100
What happens when a a gas loose heat energy and how is this process called?
It transforms into a liquid and is called condensation.
200
Mention 3 characteristics of a Scientific claim.
1. Follow the scientific method 2. Can give supporting evidence 3. Is reliable/repeatable
200
What is atomic weight?
Is the average mass of the naturally occurring isotopes of an element.
200
What is a solution?
Is a type of homogeneous mixture formed when one substance dissolves into another.
200
Mention 2 traits of solid.
-Definitive shape. - Definitive volume.
300
What is the formula to find the density of an object?
Density ÷ Mass = Volume
300
What is sublimation?
When a solid changes into a gas.
300
What is an ion bond?
When the charges between each atom are no longer balanced.
300
What is a Covalent Bond?
Electrons that are shared between atoms.
300
Which state of matter has enough energy to slide past each other?
Liquid.
400
What is a circle graph?
A circle graph is a graph that is made by dividing a circle into sections or categories.
400
Give 2 examples of plasma.
Stars and lighting.
400
Why isn't a good idea to classify matter by its phases?
Because one kind of substance can exist in more than one phase and matter changes phases rather easily.
400
What are the 3 characteristic properties of ionic compound?
1. Crystal Shape. 2. High melting point. 3. Electrical Conductivity.
400
What is Bernoulli's Principle?
Are states that as the speed of a moving fluid increases, the pressure within the fluid decreases.
500
Mention the scientific method in order.
1. Purpose 2. Hypothesis 3. Materials 4. Procedure 5. Data 6. Conclusion
500
What is Archimedes’ Principle?

The buoyant force acting on a submerged or floating object is equal to the weight of the displaced.
500
When a radio decay occurs?
A radio decay occurs in nucleus that are unstable.
500
Mention 2 chemical properties.
Flammability and reactivity.
500
Why the sky is blue?
Because molecules in the air scatter blue light from the sun more than they scatter red light.
