Here are a few resources:
Coal, Water, Gasoline, Wind, Sunlight
Which are Non-renewable?
Coal, Gasoline
Which part of an electric circuit creates the current of electricity?
battery
Define "Renewable".
A resource that is abundant and won't run out any time soon. We can get more.
Tim warmed his mug before making his coffee.
Moby got a cold mug from the cabinet.
Explain whose coffee will get colder faster, and WHY?
Moby's coffee will get colder faster because the heat from his coffee will transfer to the cold mug to warm it up.
Tim's mug is already warm= less transfer of heat from the coffee.
