Preschool Science Experiment for Kids - Bottle Greenhouse

Plastic Bottle Greenhouse - Science Experiment
Science Experiments For Kids



What You Need For This Science Activity:



 Some soil
 Seedlings, seeds or small plant
 Tape
 Scissors
 Clear plastic water bottle or beverage bottle with cap





Procedure for This Science Experiment:



1. Make sure the plastic bottle is rinsed out well. It doesn’t have to be completely dry inside.

2. Carefully cut the plastic bottle in half using the scissors.

3. Being careful of sharp edges - take the bottom portion of the plastic bottle and fill it about half way with soil.


4. Plant either your seeds, or seedling in the soil-making sure it is lightly covered with soil.


5. Carefully place the top portion of the plastic bottle back on top of the lower portion of the bottle. Seal them together with the tape and make sure there are no small holes that air or liquid can escape from.


6. Place just a few drops of water in your bottle greenhouse. Put the cap back on top of the bottle.


7. Place your Bottle Greenhouse near a bright window where it can get lots of sun and warmth.


8. In a few days the bottle will begin to ‘sweat’ inside. This is condensation which will help to keep supplying the seeds or plant with moisture to help it to grow. If it is too wet inside open the cap for a while to let it dry out for a little bit.


9. Check it daily and you will gradually begin to see the plant or seeds growing.





Fun Science Facts For this Kids Science Activity:



Sunlight and it’s warmth, cause the temperature inside the bottle greenhouse to rise.

Because it is sealed with a cap or a lid, the sealed air inside stays heated even though the outside air may cool down.

The air inside the Bottle Greenhouse turns to water which feeds the plant to keep it healthy and alive.
