Sorting Flower Seeds

EXPERIMENT

You will need: ﬂower seed packet, wooden

stick, large pot, large dish, soil pellet, sheet

of white paper, water, sunny windowsill

There are six types of ﬂower seeds in

the seed packet. Carefully pour some

of the seeds onto a sheet of white

paper.

Using these pictures and a wooden

stick (or tweezers), ﬁnd a few of each of

the six types of seeds.

You can plant the seeds you just found

in the large pot. Save 1/2 measuring

cup of seeds for the seed bombs (next

experiment). You don’t want to plant

too many at the same time, because

they will crowd each other when they

grow.

Keep the pot in a sunny window and

water it whenever the soil gets dry.

When the plants get too large for the

pot, you can transplant (move) them to

a larger pot or to your garden outside.

WHAT’S

HAPPENING?

Seeds and plants come in a huge variety of

shapes and sizes. You can tell them apart

based on their characteristics, like seed

shape, leaf size, ﬂower color, fruit shape, and

so on. There are about 400,000 diﬀerent

species of plants on Earth. A biological

species is a group of lifeforms that can breed

(reproduce) together but cannot breed with

other groups.
