Final lab
Introduction
Have you ever planted a seed and it did not grow? This is primarily because the seed did not germinate. The first process of a seed becoming a plant is germination. Many factors can affect whether a seed germinates or not. Some of the factors can be the type of soil the plant is in, the amount of water the plant ,or even the temperature or condition the plant is in. these factors can affect the seed’s rate of germination. The rate of germination is one of the key elements in determining the quality of any seed.
The purpose of this lab is to study the effects of temperature on seed germination rate.
Hypothesis
If the temperature of the soil is warm then there will be a higher seed germination rate.
Materials
Heater, 2 plant pots, 2 bean seeds, soil (amount may vary depending on the size of plant pot), thermometer, gloves, mini shovel, water, ruler.
Procedures
Put equal amount of soil in each pot using the mini shovel.
Plant a bean seed in each pot using the gloves.
Water each plant with equal amounts of water.
Label the pots A and B.
Leave pot A at room temperature; using the heater and thermometer, heat up pot B soil to 7o degrees Celsius. Use the thermometer to check the temperature.
You are going leave the pots overnight for a week. Every day you will observe and record you data.
Using a ruler you will measure the length of both plants every day.
Record and graph your data
Variables
Dependent variable: height of plant
Independent variable: time
