What is growing season, and how does the temperature affect the growth of a plant?
Things Required:
8 pinto beans
Paper towels
2 drinking glasses
Directions:
Prepare both glasses as follows:
a. Fold one sheet of paper towel and line the inside of the glass with it.
b. Wad the sheets of paper towels and stuff them into the glass to hold the paper lining against the glass.
c. Place four beans between the glass and the paper towel lining. Evenly space the beans around the centre of the glass.
Moisten the paper towel with water. The paper is to be damp, not dripping wet. Place one glass in the refrigerator and keep the other at normal room temperature. Keep the paper in both glasses moist. Observe each glass for one week.
This Is What Happens:
The beans at room temperature have started to grow, but the ones in the refrigerator are unchanged.
Science Behind It:
Seeds need a specific temperature to grow and beans require warmth. Very few seeds sprout during the months of autumn and winter. Most lay dormant, unchanging during the cold parts of the year, and start to grow when the ground warms.
