Electrical converting to light.When Athena, because she lives in a lovley castle with electricity (bare with me here) she turns on the lights!When she flips a switch, the electrical energy is converted into light energy.
Later, Athena goes to ride her horse around but before she does she eats some fruit to power herself, thus chemical to mechanical energy.
Light to chemical-Athena hopped of her horse and went to water her garden, while the sun is shining on the plants thus making them grow thus converting it into chemical engery.
Because this wonderful kingdom has electricity. She makes a chemical to light conversion by turning on her battery powered flashlight! Only because its getting really dark out.
Athena gets home after a long day! She is very sleepy and wants to make some toast- this is a electric to heat reaction.
