Plant Growth Project's Conclusion & Cost

Conclusion


We found that in order for seeds to germinate and grow successfully through a plant cycle, it is critical for them to be in stable, environmentally friendly conditions were there is enough food, water, and sunlight.



Project Summary



Difficulty 4

Time Required 6 Weeks

Material Availability Easily Acquired

Cost $20-40

Safety Minor injury possible. Adult supervision recommended during lab.

Plant Growth Project Variables

Control- Project will be conducted in a 4th grade classroom setting, and facilitated weekly by the Researcher of the Science Project, and Project Monitor. Control group participants will do a Read-Aloud of One Bean written by Anne Rockwell, and Illustrated by Megan Halsey. Students will use the Science Lab at the facility to pot their own seedling, and create a chart to mark bi-weekly changes.


Independent Variable- Researcher will conduct similar experiment in a home environment of Ivy sprouts planted in Soil, Sand, Pond Water, and Gravel. Researcher Wondering: Will the plants germinate or sprout differently under incandescent lights which give off heat; and, will the environment yield varying results since under controlled and consistent conditions.

Dependent Variable- Researcher will have school project conducted under the guidance of a Facilitator, in a classroom setting where there are fluorescent lights that are cooler than incandescent lights. In this environment, Researcher noticed that the construction work being done in and around the building might affect the outcome of the experiment. Conditions of the classroom varied from very cool to dry heat.

Plant Growth Hypothesis, Problem, & Materials

Hypothesis

Can a plant germinate in different biomes, climates, or conditions?

Problem

During the experiment, the control group found that there has to be consistency in any environment in order for a plant to germinate and take root, or, it will die.

Dallas ISD 7th Grader's Final Report for Plant Growth

Abstract


Have you ever wondered why certain plants grow in one area, but not in others? This could probably be influenced by the climate, temperature, and availability of water. Fluctuation in temperature and lack of water tend to go hand in hand along with the availability of sun and altitude. In this science project, you will learn about four different biomes, soil, sand, gravel, and pond water; and how climate conditions can affect plant growth.

Objective


This project seeks to investigate the effects of different biomes on plant growth.

Introduction

Let’s take a look at the meaning of biome: a biome is the habitat in which the organism lives. Its climate and region dictates how it germinates based on temperature, availability of water, food, and sunlight. Based upon were a plant grows, the vegetation changes from the south or north. Example, here are a few places where botanist have studied varying biomes of plant life:

1. Rain forest

2. Temperate forest

3. Taiga (boreal forest); and

4. Tundra

In looking at the vegetation world map, we have found that the Desert is the largest biome, and is not good for plant growth. This is probably why the seeds planted in gravel of this science fair project did not succeed. In relation to soil growth, it can be the most productive, or the least. Where nutrients are plenty, plant cycle is strong; but, where it is week, such as a home setting, fertility declines.
