This property tells if an object will sink or float in water.
What is density?
A push or pull on an object is called this.
What is force?
A circuit must be complete for this type of energy to flow.
What is electrical energy?
Earth spinning on its axis causes this daily pattern.
What is day and night?
Living parts of an ecosystem are called this.
What are biotic factors?
This state of matter has a definite shape and volume.
What is a solid?
This simple investigation might involve a car rolling down a ramp.
What is testing the effect of force?
Electrical energy can change into this when a bulb lights up.
What is light energy?
One full rotation of Earth takes about this long.
What is 24 hours?
Nonliving things like water and sunlight are called this.
What are abiotic factors?
This property describes how well something lets heat or electricity pass through it.
What is conductivity?
This changes when you push or pull an object.
What is motion (or position)?
Light travels in this type of path.
What is a straight line?
Moving water, wind, or ice can form this like canyons or dunes.
What are landforms?
Organisms survive because of this relationship with their environment.
What is interaction?
A mixture like sand and iron filings can be separated because each substance keeps this.
What are physical properties?
Increasing force on an object will usually do this to its motion.
What is increase speed/change motion?
When light bounces off a surface, it is called this.
What is reflection?
Layers of rock pressed together form this type of rock.
What is sedimentary rock?
Fossils provide evidence of this.
What are past living organisms?
When substances dissolve and form a solution, this stays the same.
What is mass (matter is conserved)?
A good experiment must change only one of these at a time.
What is a variable?
A circuit that does not work is missing this key feature.
What is a complete path (closed circuit)?
The Sun appears to move across the sky because of this.
What is Earth’s rotation?
A structure that helps an organism survive is called this.
What is an adaptation?
