Four Plants — Which Bloomed First?
Lesson 3 of 9
About this lesson
Four plants bloom at different times across a school: geranium in the canteen, guppy plant in the music room, wax plant in the school hall, bromeliad in the library. Three clues tell you the relative order. The key is Clue 2: the geranium bloomed on the same day as the school hall plant — which means you need to identify the school hall plant before you can place the geranium.
