Pea Maze

EXPERIMENT

You will need: pea

seedling from previous

experiment, small pot, small dish, soil

pellet, pipee, water, shoe box, scrap

cardboard, scissors, tape, coon balls,

sunny windowsill

Now you can construct a pea

maze, as shown in the images.

Use a box and scrap cardboard

(for example, from a shoe box

or cereal box). An adult needs

to help with the cuing and

assembly of the maze.

Plant one of the peas you

sprouted into a small pot, put it

in a small dish, and put it in the

boom of the maze.

You can pack some coon balls

around the pot so it stays in

place.

Let the plant grow for two weeks.

Check the pot daily to make

sure the soil is moist. Water as

needed. Open the box carefully

so you do not disturb the plant or

pot. Aer watering, close the box

carefully.

What did the pea plant do

inside the maze as it grew

for two weeks?

Note: You can plant the rest of

the pea seeds whenever you like.

First sprout them by soaking them

in water overnight.

WHAT’S

HAPPENING?

Your plant senses the direction

the light is coming from and

grows toward it. It can even

wind its way through a maze

over the course of a few weeks!

This works because the side of

the stem that is darker grows

faster, so the stem bends

toward the light.
