Help the children to make a science journal. The children should include the date (very early grades the teacher may choose to provide a date stamp and ink pad) and the materials they needed. Include a picture drawn by the child or cut from a magazine, and have the child write a sentence or two about the project and their findings.
Recording the Results:
Have the children draw and write what they observed in their science journal.
P.S. Question Part 2: Why are plants important?
Dangerous chemicals fill our air, water, and soil. These pollutants come from chimneys, car exhausts and factories and pesticides. These poisons remain in our soil or get washed into rivers and streams changing clean water into poison.
In their book, Nature Quest, James and Priscilla Tucker share the following information. Our homes also contain poisons that threaten our health. Our draperies, carpets, and upholstery contain solvents such as trichloroethylene and chloroform. Benzene appears in the dyes found in these substances while formaldehyde is a component of plastics and insulation. The invisible vapors released by these items causes reactions ranging from allergies to cancer in our bodies.
The marvelous way in which plants were created helps them to serve as a natural combatant to some of these pollutants. Trees and plants absorb air storing carbon dioxide and these pollutants in their cells. They then release pure, clean oxygen into the atmosphere. This process is reproduced over and over again as these clean air machines do their part in helping to protect our environment.
In the home certain houseplants, such as aloe vera, philodendron, English ivy, peace lilies, and others help to cleanse the air of formaldehyde, benzene, and trichloroethylene. Not only do these plants help to clean the air but their aesthetic beauty is also rewarding.
