Scientific Method
A student changes the amount of sunlight a plant receives and measures how tall it grows. This is the variable being measured.
Dependent variable
Everything around you is made of these tiny building blocks of matter.
Atoms
This tool is best used to measure the volume of a liquid.
graduated cylinder
This structure surrounds plant cells and provides support and protection.
Thus structure provides a filling between organelles that holds everything in place.
cell wall; cytoplasm
The boundary between two air masses is called this.
front
A student changes the temperature of water to see how fast sugar dissolves. This is the variable being changed.
independent variable
Rust forming on a bicycle is an example of this type of change.
Chemical change
These two tools measures mass.
triple beam balance and scale
These organelles allow plants to make sugar using sunlight. What is the process of making sugar from sunlught called?
chloroplasts; photosynthesis
This type of front forms when two air masses meet and neither one moves very much.
stationary front
In an experiment testing whether music affects plant growth, all plants receive the same amount of water and are the same species. These are examples of this type of variable.
Constants
This occurs when two or more atoms join together to make a new substance
compound
A bottle contains 2 liters of water. This is the equivalent volume in milliliters.
2,000 mL
A squirrel and a hawk belong to this kingdom and domain.
animal kingdom and eukarya
The day-to-day conditions of the atmosphere are called this.
weather
Scientists keep all conditions the same except one so they can determine what causes changes in the results. Why do they do this?
They have to ensure only one variable is being tested
A substance made of only one type of atom is called this.
element
A bag of flour has a mass of 4 kilograms. This is the mass in grams.
4,000 grams
An organism made of only one cell is described using this term.
unicellular
The average weather patterns in an area over many years are called this.
climate
A student tests whether fertilizer affects plant growth. The plants that receive no fertilizer belong to this group.
Control group
What is the chemical formula for sugar?
A graduated cylinder contains 750 mL of liquid. An object is dropped inside of it and the water in the cylinder raises to 847 mL. What is the name for the process being done here?
Water displacement
This organelle controls the activities of a eukaryotic cell.
nucleus
A cold front is moving into an area. This type of weather often occurs as it passes.
thunderstorms or heavy rain
