Ecosystems
This organism makes its own food using sunlight.
producer
This state of matter has tightly packed particles that keep their shape.
Solid
What tool or method could you use to separate sand from water?
What property of matter is measured in meters?
Length
What type of consumer only eats plants/producers?
Herbivores
In what state of matter do particles float around freely, completely spread out?
Gas
Is evaporation a physical or chemical change?
Physical
What property of matter is measured in degrees Celsius or Farenheit?
Temperature
An animal that eats both plants and animals.
Omnivore
When water is heated, what happens to the particles in the liquid?
They speed up/move faster
Is rust forming on nails a physical or chemical change?
Chemical
What property of matter is measured in grams?
Mass/weight
If there are less rabbits in an ecosystem, what will happen to the fox population?
Decrease (have less food)
Fill one balloon with water. Fill another with gas. What would happen if you open both?
The liquid would spill out (or stay if you hold it upright). The gas would float out as soon as the balloon is opened.
Is saltwater a mixture or solution? Explain why.
Solution because the salt dissolves and spreads out evenly throughout the water.
What property of matter is measured in milliliters?
Volume
If all producers disappear from an ecosystem, what would eventually happen to all the consumers?
Water (H2O) is an example of this because it is made of more than one element chemically combined.
Compound (I'll also accept molecule)
Two equal blocks of clay have the same mass. One is reshaped into a bowl. Both are weighed again. Would they have the same mass or different mass? Why?
Same because of the law of conservation of matter.
What is conductivity?
How well heat or electricity moves through a substance.
