Science project idea on how plants and animals make use of the food manufactured by plants.
Food Manufactured By Plants- Science Project Idea
Why must plants and animals have food?Compare the growth of a bean or pea seedling, from which the seed leaves have been removed, with the growth of one from which they have not been removed.What is the result?Since the food for the growing seedling is stored up in the seed leaves, what is your conclusion?
Your observations are sufficient without any experiments to prove to you that animals also must have food.The question is: Why is food so necessary?
We know that animals and plants exert energy.Plants are able to push their roots through the soil and against the force of gravity Give examples of this.Likewise, animals have the power of movement, produce heat, and are able to do work.Knowing that animals and plants breathe in oxygen and breathe out carbon dioxide, and that food must be taken in, what is your conclusion as to what happens to some of the food in the body?One use of food, therefore, is to act as a fuel which when burned furnishes heat, and power to do work.
Another use of food is evident to you; you weigh more this year than you did last year; you say that you have grown ; your bones have become longer and thicker ; muscles are larger ; heart is a little bigger, etc. Where did the additional material come from?What, then, will you conclude is another reason why plants and animals, and we, ourselves, must take in food?
In the work of the body there is a certain amount of wearing away of its parts.This wear evidently must be made good by food being built up into the muscles, nerves, and other parts of the body.State, now, the three uses made of food by plants, animals, and the human body.
Our next question naturally will be: What foods are good for each of these purposes?
Science Project Idea Present what are the different benefits we obtain from plants.Explain and present the Photosynthesis and the Nitrogen Fixation cycle of the plant and how it affects the animal.Show diagrammatically.
