Science Review 5 Grade

Question 1

Describe some examples of physical properties.

Answer 1

Size, shape, odor, temperature, mass, weight, volume, density, texture, color, and light can or cannot pass through it.

Question 2

What is matter?

Answer 2

It is something that has mass and volume

Question 3

State what each of the following is, what instrument is used to measure it, and what units are used. Mass, weight, and volume

Answer 3

Mass: the quantity of matter in a material, triple beam balance, grams and kilograms. Weight: a body’s relative mass or the quantity of matter contained by it, spring scale, pounds and ounces. Volume: is measure of the amount of space that a substance or object takes up, cm tape, fluid ounces.

Question 4

How are mass and weight different?

Answer 4

Mass is how many atoms are in the item, but weight is the gravitational pull.

Question 5

Name three states of matter.

Answer 5

Solid, liquid, and gas.

Question 6

Describe the following. Solid, liquid, and gas

Answer 6

Solid: definite shape, definite volume, and particles do not move from place to place. Liquid: no definite shape, definite volume, but takes on shape of its container, and particles slide by each other. Gas: no definite shape, no definite volume, but takes on shape of its container, and particles move freely.

Question 7

For each phase change be to indicate if heat/energy is put in or taken out.

Answer 7

Solid add heat liquid add heat gas take heat out liquid take heat out solid

Question 8

Temperature is ___________________________________________________

Answer 8

Temperature is a measure of the average heat or thermal energy of the particles in a substance

Question 9

What is a chemical property?

Answer 9

A chemical property describes the way a substance reacts with another substance.

Question 10

Describe some examples of chemical property.

Answer 10

Is it flammable, is it nonflammable, does it rust, does it corrode?

Question 11

What is a physical property?

Answer 11

Something that can be observed or measured

Question 12

What is a physical change give examples

Answer 12

Substances keeps the same chemical property, but changes form. Ice melting.

Question 13

What is a chemical change, give examples

Answer 13

Results in a change in the identity of matter, lighting a match, bleaching clothes

Question 14

State the 4 clues that indicate that a chemical change has taken place.

Answer 14

Produces gas, gives off or takes in heat/light, color change, and forms a precipitate.

Question 15

What is a chemical reaction? Give an example of a chemical reaction.

Answer 15

It is when 2 or more substances react and new substances form. The baking soda and vinegar reaction made a gas.

Question 16

Define the following and give an example of each, mixture, solution, alloys.

Answer 16

Mixture: substances keep own properties no chemical change, when 2 or more substances are combined, granola, fruit salad. Solution: one substance dissolves into another, particles stay mixed, and evenly mixed, particles are very tiny, particles can be separated, ocean air and brass. Alloys: mixture of 2 or more metals, made by heating metals mixing together.

Question 17

Be able to discuss what you learned in the following experiments: measure mass with triple beam balance scale, measure volume with a cm tape and water displacement, density demonstration with oil, water, syrup, celery, and raisin.

Answer 17

OOOOOOOOOOOOOOKKKKKKKKKKKKKKKK!!!!!!!!!!!!!
