If something measures directly in between 50 mL and 60mL, how many mL is it?

55 mL.

100
The first step in the scientific method.

Problem (question)

100
The smallest unit of matter. 

An atom

100

What powers the water cycle?

The sun
100

What celestial body orbits the Earth?

The moon

200

What tool would you use to measure a liquid?

Graduated cylinder, Erlenmeyer flask, beaker 

200
What is a hypothesis?

An educated guess as to what will happen in an experiment.

200

Two or more atoms combined.

What is a molecule?
200

What is the main source of water for the water cycle?

The ocean

200

What process gives us day and night?

The Earth rotating (spinning in a circle), it takes 24 hours
300

Where should you look when measuring a liquid?

Eye level
300

What are the 3 types of variables in an experiment?

independent variable, dependent variable, controlled variable

300

Describe acids.

Sour, dissolve metal, change color, burn

300

Name the 4 steps in the water cycle.

Evaporation, condensation, precipitation, collection (accumulation)

300

What are the names of the planets in our solar system?

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

400

What tool would you use to measure mass?

Digital scale or triple beam balance

400

What NEEDS to be collected in any experiment?

Data

400

What is the law of the conservation of matter?

Matter is neither created or destroyed, it only changes forms.

400

Why is preserving fresh water so important?

Only 3% of the water in the world is fresh water (1% is not frozen) we need fresh water for so many different things and we cannot use saltwater for it (showers, drinking, cooking, toilet, dishwasher, etc)
400

What causes the seasons? How long does this process take?

Earth's revolution (orbit) around the sun. 365.25 days

500

The name of where you should look to measure a liquid. (the curve of a liquid in a container)

What is the meniscus?

500

The last step in the scientific method.

Conclusion and Report

500

What does the law of the conservation of matter mean?

Give an example. (in an experiment were baking soda and vinegar are combined in a closed environment, the total mass at the beginning will be the same at the end).

500

Define/explain all 4 steps of the water cycle.

Evaporation: when the sun heats the water up enough to turn it from a liquid to a gas.

Condensation: when the water vapor (gas) gets high enough in the school that the air is cold and cools the gas back to a liquid droplet (how clouds are made)

Precipitation: rain, snow, sleet, hail

Collection/Accumulation: water that is collected (ponds, lakes, oceans)

500
Even though the Sun is not the biggest star in the universe, why does it appear so bright?

It is the closest star to the Earth so it appears both bigger and brighter.
