You will probably need an adult to help you cut the bottle because that may be a bit difficult. Here are materials you will need to gather:
- Two 2-liter soda bottles,
- One bottle cap
- Duck tape
- One piece of heavy cotton string cut about 6 inches long
- Distilled water
- 8- 1- cm of planting soil
- And a couple of small plants with the roots attached.
- Optional, pill bugs (Isopods) worms, or a land snail.
What to do:
- Step 1: Cut the two 2-liter bottles as shown above.
- Step 2: Using duct tape, connect the three pieces as shown in the middle picture.
- Step 3: Drill or punch a hole in the bottom lid and place a cotton string through it.
- Step 4. Fill the top portion with 8 – 10 cm of planting soil.
- Step 5. Fill the bottom portion with a “pond: of distilled water so the cap is just above the water line.
- Step 6: Plant two or three small plants in the soil.
- Step 7. (Optional) add some pill bugs, worms or a snail to you bottle.
Now you have created a complete ecosystem as your Earth Day project. Keep a log and record every day what happens inside your very own ecosystem. And as you are out walking or playing, look around and see how many “ecosystems” you can find.
Happy Earth Day!
