Kavi Enters the Olympiad Lab
Kavi walks into the Science Olympiad Lab and sees a results chart on the wall 📊. "In this lab we don't guess — we read the data and find the best explanation. The best one fits every result, not just one, and it never ignores the numbers. Put on your lab coat 🥼 — let's reason to the true answer together!"

2Results: how tall did the plants grow?A team grew the same seed in three places and measured each plant. A taller bar means a taller plant. Read the results, then look for the pattern.
3Which explanation fits ALL the results?Read both results, then tap the explanation that fits them BOTH. Tap Next test for more.
4Best explanation or weak guess?What's the difference? Tap each card.

A peek inside
Results: the sunny plant grew tall, the dark plant stayed short. What is the best explanation?
Both results point the same way: more light, taller plant. 'Just lucky' ignores the data, so I cross it off.
Try this at home: How many of the results must the best explanation fit?
