- There is a rain cloud in the sky - Small bits of ice within the cloud bump each other - The collisions create electrical charge - Lighter, positively charged particles sink to the bottom of the cloud - Heavier, negatively charges particles rise to the top What might be the last step of the process?
Ans: When the positive and negative charges grow large enough, a giant spark, called lightning occurs

- Bats fly through an area - The bat makes sounds with their mouth or nose - The sound waves travel away from the bat - The sound waves hit objects - The sound waves bounce off the objects back towards the bat - The bat hears the sound waves echoing off the objects - The bat knows where the objects are because of where the sound echoed from What might be the last step of the process?
Ans: The bat doesn't hurt itself by hitting the objects.

- Carbon dioxide enters the leaves through the stomates by diffusion - Water is transported to the leaves in the xylem - Energy harvested through light reaction is stored by forming ATP - Carbon dioxide and energy from ATP are used to create sugar - Oxygen exits the leaves through the stomata by diffusion What might be the last step of the process?
Ans: The plant reuses the water or the water exits through the stomata as water vapor.
