Step-by-step guide to design and build a model alien lifeform
Why extremophiles bode well for life beyond Earth - Louisa Preston
Step 1
Imagine a planet and give it a name by thinking about its weather colors and landscape.
Step 2
Draw your alien and its planet on the paper with a pencil so you know what to build.
Step 3
Choose the clay and the recycled bits you will use for the alien and its habitat.
Step 4
Roll and shape the clay to make the alien’s main body using your hands.
Step 5
Attach recycled pieces to the clay body to make arms legs eyes or special tools using glue tape or toothpicks.
Step 6
Add small details like textures patterns or decorations with toothpicks paint or colouring materials.
Step 7
Cut and assemble a cardboard base to make the alien’s habitat and glue down terrain features like rocks plants or water.
Step 8
Think of three adaptations your alien has and write each one on the paper with a short sentence explaining how it helps the alien survive.
Step 9
Place your alien on the habitat base and arrange the scene to match the environment you drew.
Step 10
Share your finished alien model and its story on DIY.org
Help!?
What can we use if we don't have clay, toothpicks, or cardboard for the alien project?
If air‑dry clay isn't available, make salt dough or use play‑doh for the alien body, substitute toothpicks with short skewers or cut drinking straws to attach recycled bits, and use a cereal‑box panel or paper plate instead of cardboard for the habitat base.
My alien's arms keep falling off—how do I fix that?
If recycled pieces keep falling off the clay body, press a toothpick or small skewer into the clay as an internal armature, score both the clay and recycled piece, and secure with strong glue or tape until dry so arms and tools stay attached.
How can I change the activity for younger or older kids?
For younger children, pre‑cut the cardboard base, use larger recycled pieces and tape instead of glue, and skip the written adaptations, while older kids can add fine paint details, electronics, or a full written page explaining the three adaptations and planet name.
What are some ways to make the finished alien habitat more special or display‑ready?
Enhance the scene by adding textures with toothpicks and paint, glue on labeled terrain features to the cardboard base, incorporate a battery tea light or movable limb hinge, and include the three written adaptations and planet name for sharing on DIY.org.

Facts about astrobiology and planetary adaptations
🛸 Scientists have discovered thousands of exoplanets—some orbit stars very different from our Sun!
🔬 Astrobiology looks for chemical signs of life, like water, oxygen, or unusual gases in a planet's atmosphere.
🌋 Life on Earth can thrive in extreme places—dark deep-sea vents and frozen deserts—so life elsewhere might be hardy too!
🧪 Alien life might not need water; moons like Titan have liquid methane that could host very different chemistry.
♻️ Making aliens from recycled materials is a fun way to upcycle and practice creative engineering and design.
