Things you will need:
- Clear plastic bottle (s)
- Planting soil
- Small plant or seedling
- Wide tape
Select right bottle
Take a recycle clean plastic bottle and wash it properly in order to clean it.
Note: You can use a large empty soda bottle.
Plant a seedling
Now, select a healthy small plant or a seedling and fix it in the soil, inserting its roots into the soil of the bottle.
Note: Make sure that all roots of the small plant or a seedling are thoroughly covered by the soil.
Attach both parts of bottle
Once you fixed the plant, gently place the top part of the plastic bottle back on to the lower part. Repeat the above mentioned steps with the other bottles to make more Mini greenhouses for your science fair project.
Seal the bottles
Now, thoroughly seal both portions of the bottles together with a wide tape, making sure it is air tight and there is no leakage.
Water the seedlings
Remove the caps of the bottles and pour in few drops of water into the bottles.
Seal the caps of the bottles
Place the cap of the plastic bottles back on the top and seal them carefully.
Your mini greenhouses are ready
Your mini greenhouses are all set; place them somewhere with proper lighting so that they can get the required sunlight.
Leave it for few days
Leave your mini greenhouses there for few days.
Inspect your mini greenhouses
After a few days, inspect your mini greenhouses and notice the recycle plastic bottle "sweating". If you find the bottles with too much moist, simply open their cap and let it dry out for a while.
Note of the improvement in the growth
Inspect your plants inside the greenhouses at least once per day and note their growth, making a note of the measurements. After one week, you will notice an amazing change in your plants' growth.
What do you really think is the main component that played a vital role in your plant's growth? The sunlight causes the temperature inside the greenhouse to rise and the trapped air inside the bottle turns to water. In this way, the plant inside the Mini Greenhouse was getting proper sunlight and water, which are one among the basic requirement for the growth of plants.
Benefits of this Science Fair Project
This Science Fair Project is fabulous idea to protect your plants during winters and in the areas with cold climate and temperature. The plants during winter do not get the proper warmth that plays important role in their growth. This is the time when you should have the amazing idea to build your own greenhouse.
