How much does an apple weigh? How hard can you pull? The spring scale shows it directly: the spring extends, the pointer moves, grams and newtons sit side by side. Physics becomes visible — with the transparent casing you can even see inside.
Quick Overview
- 500 g / 5 N: practical measurement range for nursery and school experiments
- Double scale: grams and newtons — weight and force
- Transparent: the spring is visible — the principle is understandable
- Weigh and pull: two experimental worlds in one device
- From 3 years old: robust enough for young explorers
Ways to Use It
Daniel hangs an apple from the hook — the spring visibly stretches, the pointer moves. 150 grams. Marie pulls horizontally, as hard as she can — 4 newtons. They compare, laugh, try with a sponge, a stone. Who can stretch the spring the furthest?
