Growing Bean Sprouts - Part 1

Dr. Boyd demonstrates how to grow bean sprouts using two methods without soil. The video explains seed dispersal using apples and dandelions as examples. The experiment involves using paper towels and Ziploc bags or cotton balls and cups to sprout beans. After a few days, both methods show successful growth of bean sprouts, demonstrating that soil is not necessary for initial plant growth.

What materials are needed for the first method of growing bean sprouts?

• Soil, pot, water, dried beans

• Cotton balls, cup, water, dried beans

• Paper towel, zip lock bag, water, dried beans

• Sand, glass jar, water, dried beans

How do apple seeds typically get into the ground to start a new tree?

• They are washed away by rain

• They are revealed when the apple rots away

• They are carried by the wind

• They are planted by animals

What happens to dandelion seeds that allows them to spread?

• They are carried by insects

• They are eaten by birds

• They are blown by the wind

• They are buried by squirrels

What is the purpose of dampening the paper towel in the first method?

• To make the paper towel heavier

• To prevent the beans from drying out

• To clean the beans

• To provide moisture for the beans to sprout

In the second method, where should the cup with cotton balls and beans be placed?

• In a dark cupboard

• In direct sunlight all day

• Somewhere with some sunlight

• In a refrigerator

What was observed in the experiment using cotton balls after a few days?

• Beans remained unchanged

• Sprouts beginning to grow

• Only roots growing

• No growth at all

What conclusion can be drawn from the experiment results?

• Beans cannot sprout without soil

• Both methods successfully grew sprouts without soil

• Only the cotton ball method worked

• Only the paper towel method worked
