Step-by-step solution for: STEM Challenge Worksheets - Homeschool Printables for Free
This worksheet is designed to help students understand external features of living things by completing the missing half of each organism. The task involves drawing the mirror image of each partially shown living thing to complete its symmetrical form.
Let’s go through each of the four images and describe what should be drawn to complete them:
---
- What's shown: Half of a flower with petals, a center, stem, and one leaf.
- External features: Petals, stamen (center), stem, leaves.
- How to complete it:
- Draw the other half of the flower so that it mirrors the left side.
- Add symmetrical petals on the right side.
- Complete the stem going downward.
- Add another leaf on the opposite side of the existing one.
- The flower should look balanced and symmetrical.
> ✔ Result: A full flower with five or six petals, a central circle (possibly representing the stamen), and two leaves on the stem.
---
- What's shown: One side of an octopus with tentacles curling outward and one eye.
- External features: Tentacles, head, eyes.
- How to complete it:
- Draw the other side of the body and mirror the tentacles.
- Add three more tentacles on the right side to match the ones on the left.
- Add the second eye on the other side of the head.
- Ensure symmetry in the curves of the tentacles.
> ✔ Result: A full octopus with eight tentacles (four on each side), two eyes, and a rounded head.
---
- What's shown: Half of a ladybug with spots, wings, and legs.
- External features: Red shell with black spots, wings, legs, antennae.
- How to complete it:
- Mirror the half-shell to make a full oval shape.
- Copy the spots symmetrically on the other side.
- Add the other three legs (since insects have six legs).
- Draw the antennae on the opposite side.
- Add the head at the front.
> ✔ Result: A full ladybug with red wings, black spots, six legs, two antennae, and a small head.
---
- What's shown: Half of a mushroom cap with gills underneath and a stem.
- External features: Cap, stem, gills (underneath the cap).
- How to complete it:
- Draw the other half of the cap, making it symmetrical.
- Add gills on the underside of the new half.
- Extend the stem to be fully visible.
- Keep the shape consistent — the cap should be dome-like.
> ✔ Result: A full mushroom with a rounded cap, visible gills under the cap, and a straight or slightly curved stem.

| Image | Living Thing | Completed Features |
|-------|--------------|--------------------|
| 1 | Flower | Full petals, stem, leaves |
| 2 | Octopus | Eight tentacles, two eyes |
| 3 | Ladybug | Six legs, two antennae, spotted shell |
| 4 | Mushroom | Symmetrical cap, gills, stem |
---
This activity helps students:
- Understand symmetry in living organisms.
- Recognize external features (like limbs, stems, petals, etc.).
- Develop observation and fine motor skills.
- Learn about diversity in living things through visual representation.

Look closely at the shapes and patterns on the visible half and draw the same on the other side, like a mirror image!
