The beginning

Today, we created our 2-tier terrarium in a bottle.

In our water ecosystem, we included the following:

• 650 mL of water
• 18 cm Elodea
• 3 snails
• 1 1/2 flakes of fish food
• 5 fish 

In our soil ecosystem:

• 3 Zinnias
• 2 Hollyhocks
• 2 Radishes
• 4 1/2 cups of soil 

Our goal for this terrarium is to have thriving plants and living creatures to ensure we have created a successful/efficient self-contained ecosystem. We have documented our beginning and will continue to update with our observations within. 

Here are some pictures of our ecosystem in a bottle!
