Colared Carnations Dyson Science DIY Project

Colared Carnations Science Experiment

, ,

Create multi-colored flowers. Plants need a transport system to move food, water, and minerals around. Two things combine to move water through plants – transpiration and cohesion. Water evaporating from the leaves (transpiration) draws water up the plant’s stem to replace what is lost. This works in the same way as sucking on a straw. Water that evaporates from the leaves “pulls” (cohesion) other water behind it up to fill the space left by the evaporating water.

STEP 3

Put the split stems of the carnation into the cups and leave overnight.

STEP 4

The next morning you should find that your flower has changed color.
