Earth Day Word Search
Make a printable Earth Day word search in a few clicks. Start from one of our 7 word lists, from short words for kids to nature and habitats, recycling and reusing, energy and climate, oceans and water and harder science words, or type your own. Pick a level, from across and down only to all eight directions with backwards words, and a shape: a globe, a leaf, a tree or a plain rectangle. Every page can have one of 5 borders we drew ourselves, in colour or in black and white to colour in, and the PDF comes with an answer key that highlights every word and gives its row and column. For a class, type the names and each child gets a different puzzle with the same words, their name already on the sheet. Tick several lists for a pack that runs from easy to hard in one PDF. US Letter or A4, plus a PNG. Free, with no sign-up, no email and no watermark.
Nothing to upload. Puzzles are made in your browser.

The 7 word lists
| List | Words | Longest word (letters) | Starts on | Starts with |
|---|---|---|---|---|
| Earth Day for kids | 12 | 5 | Easy | Earth, Tree, Sun, Rain |
| Earth Day words | 20 | 12 | Medium | Earth Day, Planet, Recycle, Reuse |
| Nature and habitats | 16 | 10 | Medium | Meadow, Wetland, Rainforest, Mountain |
| Recycling and reusing | 16 | 11 | Medium | Bottles, Cans, Cardboard, Newspaper |
| Energy and climate | 16 | 11 | Medium | Solar panel, Wind turbine, Electricity, Battery |
| Oceans and water | 16 | 12 | Medium | Wave, Coral, Whale, Dolphin |
| Harder science words | 24 | 15 | Hard | Biodiversity, Ecosystem, Sustainability, Photosynthesis |
120 words in all, chosen by us, with no organisation or brand names. Earth Day words is the list the tool opens with. Any list can be edited before you print, and any list works at any level.
Shapes
| Shape | Grid for the Earth Day words list | Squares with letters | Words placed |
|---|---|---|---|
| Rectangle | 17 × 17 | 289 | 20 |
| Globe | 15 × 15 | 177 | 20 |
| Leaf | 19 × 19 | 155 | 20 |
| Tree | 16 × 16 | 172 | 20 |
Worked out by the tool for the 20-word Earth Day words list on Medium. Shapes use fewer squares than a rectangle of the same size, so the grid grows until every word fits. A light dashed line marks the globe’s equator, the leaf’s middle vein and the top of the tree’s trunk.
Borders and colour
Borders: Globes and leaves, Trees and seedlings, Bees and daisies, Leafy vine and Plain frame, or none. All are our own drawings, made of simple shapes so they print cleanly. Black and white prints them as outlines to colour in, with light grey highlights on the answer key.
Letters print in Helvetica, the PDF’s built-in typeface, sized to the squares. Large print makes the letters bigger where the page has room, and Light grid lines adds faint squares for younger children.
Levels and directions
| Level | Directions words can run |
|---|---|
| Easy | Left to right and top to bottom |
| Medium | Adds diagonals, down-right and up-right |
| Hard | All 8 directions, including backwards and upwards |
The tool spreads the words across the directions the level allows, so a Hard puzzle really has backwards words in it.
Class sets and packs
A class set uses the words you have on screen and makes a different grid for each name, up to 40 names, with the name printed on the Name line. A pack makes one puzzle from each list you tick, each at its own level unless you choose otherwise. Both put the answer keys at the back, so you can print the puzzles on their own.

Is this Earth Day word search free?
Yes. There is no sign-up, no email and no watermark, and you can make as many puzzles as you like.
Is there an answer key?
Yes. The PDF has the puzzle first and the answer key after it, with every word highlighted and its row, column and direction listed. Packs and class sets put all the answer keys at the back.
When is Earth Day 2027?
Earth Day is on 22 April every year, the date the United Nations lists for International Mother Earth Day. In 2027, 22 April is a Thursday.
Which level should I choose?
Easy hides words across and down only, which suits young children. Medium adds diagonals. Hard uses all eight directions, so words can run backwards and upwards too.
Is there a version for kids and one for adults?
Yes. Earth Day for kids has short words like Tree and Seed and starts on Easy. Harder science words has long words like Photosynthesis and Biodiversity and starts on Hard. Any list works at any level.
Can I use my own words?
Yes. Choose Your own words and type or paste them, one per line, such as the plants in your school garden. Phrases like Compost bin are fine: the space is left out in the grid.
Can the puzzle be shaped like the Earth or a leaf?
Yes. The tool opens on the globe; choose Leaf, Tree or Rectangle under Shape. Letters only fill the shape, with its outline drawn round it. If a long word cannot fit inside a shape, the tool says which one, so nothing is dropped quietly.
Can I make an easier and a harder version of the same puzzle?
Yes. Keep the words and change the level: Easy, Medium and Hard each make a new grid from the same list. Light grid lines and Large print help younger children.
How does the class set work?
Type the children’s names, one per line, and press Class set PDF. Each child gets the same words in a different grid, with their name printed on the sheet, so neighbours cannot copy. The answer keys follow, one per name.
Will every word really be in the grid?
Yes. After the empty squares are filled with random letters, every word is checked to appear exactly once, and the filler is changed where it made a second copy. The answer key is drawn from the same grid.
Can children colour the border?
Yes. Choose Black and white, to colour in: the globes, leaves, trees, seedlings, bees and daisies print as black outlines on white.
How do I make the same puzzle again?
Note the puzzle code under the preview (it is also on the answer key). Type it back into Puzzle code with the same words and settings to get the same grid.
Can I use the puzzles in class or sell them?
Yes. The designs are our own drawings: you may use them and anything you make with them, including things you sell, with no credit needed.
Are my words and names uploaded?
No. The puzzle and the PDF are made in your browser and nothing is saved.
