Answer:
Parental Note: This experiment can be completed independently by children 8 years of age and older. The project may require some support to track plant growth and take anecdotal notes over the span of two weeks.
Additional Note: This experiment will take roughly two weeks to complete; this calculation takes into consideration both the set up time and time needed for plant growth.
Experiment Overview:
The sun is a renewable energy source that plays a pivotal role in our everyday life, from warming the earth to the water cycle, it is an essential part of our daily existence. Did you know that the sun also plays a critical role in the growth of plants? Without the sun, plants wouldn’t get the necessary food needed to grow, reproduce, and survive.
Plants need three basic things to live: sunlight, water, and carbon dioxide. Through a process called photosynthesis, the plants use the energy from the sun to convert carbon dioxide, soil nutrients, and water into food! In this experiment, we are going to 1) observe the germination of seeds and track the growth as ‘Basil’ (a herb used for seasoning) plants emerge 2) track the growth of basil seeds exposed to three different light sources (full sun, some sun, limited/no sun) and observe photosynthesis in action! Before we begin, let’s think about these three important questions:
Can a seed grow/germinate/develop into a plant with limited or no sunlight?
How do you think a seed will grow with some or partial sunlight? What do you think the plant will look like after two weeks of growth?
What will be the difference between the three sunlight exposure plants? How do you think the plants will be alike?
Experiment Materials:
1 packet of basil seeds (other seed types can be used: grass, chives, bean)
3 small plastic cups
Potting soil
1 small shovel
Watering can
Notebook & pencil
3 different growing locations: full sun, partial/some sun, no/little sun
