Lab Safety
You should always wear these to protect your eyes during experiments.
What are safety goggles
Electricity needs this to flow
What is a complete circuit
Plants use this process to make their own food
What is photosynthesis
What is the weather
A good scientist always begins by asking this
What is a question
Before beginning any science activity, you should carefully read these
What are the directions/instructions
This is the source of energy in a simple circuit
What is a battery
This part of the plant absorbs water and nutrients
What are roots
This process slowly breaks rocks into smaller pieces
What is weathering
This is an educated guess based on evidence
What is a hypothesis
If you spill water or break equipment, you should do this immediately
What is tell the teacher
This object lights up when electricity flows through it
What is a light bulb
Animals use these structures to help them survive in their environment
What are adaptations
Moving water and wind can cause this by carrying away soil and rock
What is erosion
Scientists record these during an investigation
What are observations
Running during science investigations is dangerous because it can cause these
What are accidents or injuries
Materials like metal that allow electricity to flow are called these
What are conductors
This gas from the air is needed by plants during photosynthesis
What is carbon dioxide
Water changes into this when it evaporates
What is water vapor
This should stay the same during a fair test
What are controlled variables or constants
You should never taste or smell chemicals unless this person tells you it is safe
Who is the teacher
Rubber and plastic are examples of these because they do not allow electricity to flow
What are insulators
This carries water from the roots to the leaves
What is the stem
This instrument measures temperature
What is a thermometer
Scientists use this to explain what they learned after an experiment
What is a conclusion
