== Global Warning Greenhouse Effect
==
Purpose: To study how the thickness in plastic wrap affect the air
temperature.
Hypothesis: Believe that the thickness in plastic wrap would cause more
heat into the model greenhouse.
Background Research:
The earth's "greenhouse effect" is what makes this planet suitable for life
as we know it.
The earth's atmosphere contains gases, which absorb heat. These gases
(water vapor, carbon dioxide, methane, ozone, and nitrous oxide) are
known as "greenhouse gases." .
Greenhouses are structures designed to keep heat. The heat-trapping
ability of the greenhouse is a number of factors including the transparency
of the greenhouse cover, color of the surfaces inside the greenhouse, and
type of surfaces inside.
Materials:





Plastic wrap
Popsicle sticks
Pet friendly grass
Soil
4 flower pots/containers to hold grass
Procedure:
Step 1: Place pet friendly grass seeds into 4 flower pots, covering with soil
and water. (take grass a week to grow)
Step 2: Greenhouse will be made from flower pots, popsicle sticks and
plastic wrap.
Step 3: Each greenhouse will have a layer of plastic wrap covering each
side.
Step 4: All 4 greenhouses will be placed under the same light. temperatures
will be checked every minute.
Step 5: Greenhouse 1 will have one layer of plastic wrap, greenhouse 2 will
have two layers, greenhouse 3 will have three layers and greenhouse 4 will
have no plastic wrap.(Being the control)
====Data
==
Graph show that platic wrap with three layers get heated faster. the graph
also shows the time and temperature it got during each minute. The x-axis is the
Results:
minutes and y-axis is the temperature itself.
Conclusion: Our hypothesis is supported by the data. The greenhouse is a big part
of global warning and many its gases.
