electrical energy
light energy
mechanical energy
thermal energy
What form of energy is used to play instruments?

from mechanical to sound
from mechanical to electrical
from electrical to mechanical
Which soil will most likely have the smallest particles?
clay soil
topsoil
sandy soil
They all have the same-sized particles
What conclusions can be drawn from the data given in the graph?
Soil type 2 is made of nutrient and humus rich soil and is the best for supporting plant life.
Soil type 3 is made of nutrient and humus rich soil and is the best for supporting plant life.
Soil type 1 is made of nutrient and humus rich soil and is the best for supporting plant life.
Which soil sample would you predict to be clay soil?
Soil #1
Soil #2
Soil #3
Soil #4
Which of the above soil samples would you predict to be sandy soil?
Soil #1
Soil #2
Soil #3
Soil #4
How can you find out the amount of water that stayed in the soil of each pot?
by adding the amount of each soil sample to the volume of water poured in
by subtracting the volume of water collected from the volume poured in
by multiplying the volume of water poured in by the number of soil
samples
by dividing the total volume of water poured in by the number of samples
Which of these resources is classified in the same category as coal?
wood
wind
corn oil
petroleum
What makes coal, oil, and natural gas extremely useful resources?
They produce gases.
They are hard to find.
They can be burned to release the energy they contain.
They can be easily replaced.
Scientists are concerned that people are using nonrenewable resources faster than ever before. They are concerned because –
it takes millions of years to form nonrenewable resources.
more technology is needed to replace nonrenewable resources.
only certain nonrenewable resources can be replaced.
the cost of replacing nonrenewable resources is too great.
Are plants a renewable or nonrenewable resource?
renewable
nonrenewable
Which student was the only one to make a correct nonrenewable resources list?
Student A
Student B
Student C
Student D
