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.

Question

Some students are growing flowering plants by different windows in their school and keeping track of when they bloom.

The students put a geranium in the canteen and a guppy plant in the music room.

The geranium bloomed on the same day as the plant in the school hall.

One of the plants bloomed a day before any of the others. Which one was it?
