Earth Day Crosswords with Answers – 6 Themed Puzzles

Six themed crossword puzzles build Earth Day vocabulary across taking care of the earth, reduce/reuse/recycle, trees and plants, helping animals, saving energy, and keeping water clean. Each puzzle opens with a one-line environmental fact — for example, that recycling one aluminum can saves enough energy to power a TV for three hours — before presenting its own across and down clues. A single answers page at the end lists the solved words for all six puzzles together, organized by puzzle number.

Themes Included

The crosswords cover a wide variety of engaging, age-appropriate themes such as:

  • Seasons & Holidays (e.g., Winter, Easter, Valentine’s Day)

  • Maths Concepts (e.g., Addition, Subtraction, Multiplication, Division)

  • Everyday Topics (e.g., School, Colours, Animals, Weather)

Teaching tips & learning objectives

Learning objectives

  • Identify vocabulary related to conservation, recycling, plant biology, animal welfare, and water/energy conservation

  • Use short definition-style clues to determine a target vocabulary word

  • Read a brief environmental fact and connect it to the related puzzle's vocabulary

Teaching tips

  • Use the one-line fact at the top of each puzzle as a discussion starter before students begin solving.

  • Assign the six puzzles across a week of Earth Day activities, since each is a self-contained theme that does not depend on the others.

  • Check finished puzzles against the shared answers page, which lists solutions for all six puzzles together.

Skills covered

  • Vocabulary identification — students use short definition clues (e.g., 'Making sure places are neat and tidy') to fill in environment-themed vocabulary words.

  • Cross-referencing across and down entries — shared letters between intersecting clues help confirm each answer.

Good to know

Questions teachers ask about this resource

Do the six puzzles need to be completed in order?

No — each of the six puzzles is a self-contained theme (e.g., Trees and Plants, Saving Energy) with its own short word list, so they can be assigned in any order.
