Moisture Test

Lesson 8.6 — Weird Frogs

🦁

Kitimu says: "Rain frogs burrow underground to find cool, damp hiding spots during the heat of the day — how clever is that? Today you're going to be a moisture detective and test which spots in YOUR garden would make the best frog hideout. Grab a tissue and let's go, Cub!"

🎒 What You Need

Garden or outdoor area

Paper towel or tissue

Notebook & pencil

Small stick or trowel

Ruler (optional)

📋 How To Do It

Pick your test spots: Choose at least 5 different places to test for moisture. Good options: under a rock, in leaf litter, under a plant pot, near a dripping tap or pipe, in sand, in open sun, under a tree, and near a wall. Write each location in your notebook.
Do the tissue test: At each spot, press a dry piece of paper towel or tissue firmly against the ground or surface for 10 seconds. Pull it away and look — how wet is it? Rate each spot from 1 to 5: (1) Bone dry, (2) Slightly damp, (3) Noticeably damp, (4) Very wet, (5) Dripping wet. Record your score.
Check the temperature: Touch each spot with the back of your hand. Is it cool, warm, or hot? Frogs need COOL and DAMP spots. Write down the temperature feel next to each moisture score. The best frog hideouts are cool AND damp.
Dig a little deeper: At your dampest spots, use a stick or trowel to gently dig 2-3 cm into the soil. Is it even damper below the surface? This is exactly what rain frogs do — they burrow down to where the soil stays moist even when the surface dries out in the sun.
Rank your results: Create a "Frog Hideout Ranking" chart. List all your spots from BEST to WORST for a frog. The winning spot should be the one that is most damp AND most cool. Think about it: if you were a rain frog trying to survive a hot African day, which spot would YOU choose?

Ranger Tip: The Bushveld Rain Frog puffs up like a balloon and burrows backwards into soft sand to hide! It can stay underground for months during dry season, only coming out when the rains arrive. Its round body shape is perfect for digging.

Science connection: This is the same method scientists use to study "microhabitats" — tiny areas with their own special conditions. A spot under a rock can be a completely different world from the open ground just centimetres away!
