The most important element of any experiment is a caring adult. This activity is appropriate for
a child who has exchanged asking “why” for asking “how.”  “How do plants grow?
How do plants in the woods get started? How do the stores get all that food?”
 

- Place wet paper towels in a glass jar. Paper towel should be placed loosely, not packed down.

- Position 4-6 seeds against the insides of the jar so they can be seen. The number of seeds depends on the size of your jar. The sprouts will need room for roots.

- Place your sunflower jar in a window for light.

- Water daily with a spray bottle or sprinkle water lightly with your hands. Keep the towels a moist place for the seeds.

- In a few days sprouts from the seeds will appear. Then come roots. When the sprouts have two leaves and are two inches tall, you can plant them in a pot.

What do children learn from the activity?

• How materials absorb water
• ​What plants need to grow
• Plants are delicate when they are young
• Measurement

Potting your sunflower sprouts

- Put about one inch of pebbles or small rocks in the bottom of the pot.

- Fill the pot about half full of soil and press it down.

- Add loose soil to fill the pot and make a hole with your finger big enough to fit the sprout roots without crowding them.

- Prepare all your pots before you take the sprouts out of the jar. Remove the paper towel and sprouts and gently separate the sprouts from the paper.

- Place one sprout in the pot and gently fill the rest of the soil into the pot. Press down gently.

- Slowly add water until it drains out the bottom of the pot. (You will not need to water this heavily again.)

- If the soil level goes down, add more soil to within ½ inch of the top.

- Sunflowers need full sun to grow. Place your plant in a very sunny window or a safe place outside in the sun.

- When your seedling is too big for its pot, move it to a larger one or make a mini garden in your yard.

Extend the experience

- Place a stick or dowel in the larger pot and measure the plant’s growth. Keep a log of the growth. Sunflowers can grow from 2 feet to 12 feet tall!

Materials:

Pots for each sprout

- Recycled plastic bottles or cups make fine pots for spouts. An adult should cut the bottle to about 4 inches tall and make 3 to 4 holes in the bottom for drainage. Holes should smaller than a pencil barrel.

Old dishes or bowls for each pot

- Container can be recycled plastic or glass

Shovel

- You can use the top half of the bottle as a shovel to collect your soil if it is strong enough.

Soil

- Soil can be collected from your own yard or a nearby wooded area. Take enough soil to fill your pot(s) and the shovel.

Pebbles

- Collect a handful of pebbles or small stones.
