Micro-Wildlife Pitfall Trap Biodiversity Survey
An engaging, screen-free learning activity that builds real-world creativity and critical thinking for kids aged 7 to 9.
Materials Needed
- • Clean plastic cup or container (1 unit)
- • Garden hand trowel (1 unit)
- • Flat slate stone and 4 small pebbles (1 set)
- • Magnifying glass and soft brush (1 set)
- • Paper towels (1 sheet)
Pro Tips
- → Sink the cup so its rim sits flush with the soil surface; ground-crawling insects stumble in as they forage.
- → Elevate a flat stone over the cup mouth on 4 small pebbles to act as a rain and predator shield.
- → Check the trap the next morning and release all specimens back into the leaf litter after inspection.
Safety First
Do not touch unknown stinging insects or centipedes; handle all creatures gently with soft brushes and release them safely.

Step-by-Step Instructions
Step 1
Dig a small hole in garden soil or leaf litter using a hand trowel and insert a clean plastic cup so its rim is flush with the ground.
Step 2
Place a piece of moist crumpled paper towel in the cup bottom to give captured invertebrates a safe, humid shelter.
Step 3
Prop a flat stone 1 cm above the rim using 4 small corner pebbles as roof pillars to block rain while leaving access gaps.
Step 4
Inspect the trap the following morning, classify the beetles, woodlice, and spiders in a field log, and release them safely.
