Biochamber Construction

Electronic Lab Journal Entry

This is an example of some of the wonderful electronic lab journal entries done by the 7th grade students. Great job Vance!

SCIENTIST: Vance Poff

ELECTRONIC LAB JOURNAL

DATE: 2/18/16

TIME: 9:27

JOURNAL ENTRY: The materials we will be using for the experiment are 2 two-liter bottles, clear packing tape, gravel, sand, pond water, and cotton string. Plants in the experiment will be grass, radishes, and Elodea. Daphnia will live in the water and earthworms will live on the land. I want to create a biochamber to successfully support life. Accomplishing this goal will prove that I can support life outside of a natural ecosystem. This will be done all inside 2 liter soda bottles. I must support the life of an earthworm and daphnia. Also, I must include dirt, gravel, and water. In the aquatic part of the biochamber, the daphnia will live off of water plants in the water. There are also triops, which may eat the daphnia. The worms will live off of the dirt on the land part of the biochamber. The grass and pea plants will use photosynthesis to make the energy that the terrestrial part of the biochamber needs to live. The aquatic portion will live off of the water plants.

They did it !!!

These students designed and made their own BioChamber.

Take a look at their unique design.  Check out our blog over the next several weeks to see how it changes.

Can they do it???

Self-Sustaining BioChambers

Can 7th graders design an ecosystem that is self-sustaining? To answer this question, students will explore some of the relationships that living organisms within an ecosystem. Ecosystems work by some basic rules that students will discover as they design, build, and observe their biochambers. The supplies that students will be using are pictured/listed below.

Follow our class blog to track their progress.

It's A Bernice Day!

Class B-2 having a blast with Bernice, while also creating their final design for their Biochambers!

Class B-3 A meeting of the minds to develop a an enclosed, self-sustaining ecosystem (biochamber) with a little help from Bernice.
