Germination experiment

Introduction

This experience aims at investigating the process of germination in seeds. The seeds chosen for

this experiment are bean seeds. The experiment involves the practical process of germinating the

seeds with a close assessment to monitor the process of growth. Bean seeds are exposed to

different conditions and allowed to germinate with the progress being monitored. Later an

analysis is made and related with the hypothesis generated in an attempt to answer the research

question.

1. Research question; how long does it take seeds to germinate in different conditions?

What conditions are necessary for germination for seeds?

Hypothesis; it takes the same time for seeds to germinate at different set of

conditions.

3. Back ground information

Bean seeds grow well under warm conditions as it is for most seeds. Beans can fix their own

nitrogen from the soil and therefore require no additional fertilizer. Bean seeds are usually

planted together with other plants in what is known as mixed cropping or inter-cropping which is

involves planting different seeds simultaneously in the field. Bean seeds need consistent

moisture during the process of germination and growth.

Bean seeds are about 1/4-inch to 1 inch in size depending on the variety coming in different

colors. They are kidney-shaped seeds with a hard shell and are viable for five years. The

germination temperature is between 70 and 80 degrees F. They germinate in the soil temperature

of between 65 to 85 degrees F and not in cold soils.

The conditions set for germination for any seed varieties are

Water – this allows the seed to open or swell up for the embryo to grow.

Oxygen – to allow energy to be released to support germination

Warmth – required to improves germination

4. Procedures, methods and materials used

Materials used

a number of bean seeds, medium (garden soil for this case), water, ice cubes, 4

containers, oil, camera, note book

Method and procedure

• Put soil in 4 different containers (bottles for this case)
