This year, the science fair was won by Alex Muros. His project explained why leaves change colors in the fall. Alex was given a prize by the principal. He will also get to present his project at the statewide science fair in the spring. Alex will be taken out for ice cream by his parents to celebrate his hard work.

Rewrite the paragraph so that all of the sentences are in the active voice.
(Can someone check it and tell me if it's correct please?)

Looks good!

This year, Alex Muros achieved victory in the science fair. His project provided an explanation for why leaves change colors in the fall. The principal awarded a prize to Alex. He will also have the opportunity to present his project at the statewide science fair in the spring. To celebrate his hard work, Alex's parents will take him out for ice cream.

Your answer is almost correct! The only correction I would suggest is to change "got a prize by the principle" to "was given a prize by the principal". Here's the rewritten paragraph with that change:

This year, Alex Muros won the science fair. His project explained why leaves change color in fall. Alex was given a prize by the principal. He will present his project at the statewide science fair in spring. Alex will be taken out for ice cream by his parents to celebrate his hard work.

Great job! Your paragraph is now in the active voice.

“Alex will be taken…” = still passive.
