What is Aquaponics?
Here is one attempt at a definition:
• "Aquaponics is the cultivation of fish and plants together in a constructed,
recirculating ecosystem utilizing natural bacterial cycles to convert fish
waste to plant nutrients. This is an environmentally friendly, natural foodgrowing method that harnesses the best attributes of aquaculture and
hydroponics without the need to discard any water or filtrate or add
chemical fertilizers."
-Aquaponic Gardening Community, November 2010
• Aquaponics is the combination of aquaculture (raising fish) and
hydroponics (the soilless cultivation of plants in water) that grows fish and
plants together in one integrated system. The fish waste provides an
organic food source for the growing plants and the plants provide a
natural filter for the water the fish live in, creating a natural balanced
cycle. The third participants are the microbes (nitrifying bacteria) and
composting red worms that thrive in the growing media. They do the job
of converting the ammonia from the fish waste first into nitrites, then into
nitrates and the solids into vermicompost that that are food for the plants.
The Aquaponics cycle

LOOK at the half sheet you picked up to answer the following questions:
1. Which variable is rip-o-meter activity on the ‘Sample Test’ designed to test?
2. Which of the following conclusions is best supported by the data in the activity
on the ‘Sample Test’? Explain.
a. Jasmine leaves exposed mostly to shade are tougher than those grown in
the sun.
b. Jasmine leaves exposed mostly to sun are tougher than those grown in the
c. The amount of sun exposure does not seem to affect the toughness of
jasmine leaves.
3. If the student had tested only one leaf grown in the sun and one leaf grown
mostly in the shade, might that data have supported a different conclusion?
BR (5 min)
Talk about scientific method (10 min)
Lab: Making a Rip-O-Meter (Day 1) (30 min)
ES (5 min)
Scientific Method Steps
PURPOSE. State or define the problem.
RESEARCH. Collect information about the problem
HYPOTHESIS. Proposed explanation of the problem.
EXPERIMENT. Test your idea and collect data.
ANALYSIS. Analyze results and review.
CONCLUSION. Form an answer to the problem.
Variables & Data
Variable = what is changed in the experiment
Control = what is kept the same
Controlled Variables = variables that are being kept the
Independent variables = variable being manipulated
Dependent variables = response that is measured
If scientists wanted to test rather caffeine was really reducing
sleeping hours in adults, the variables would look like this:
• Independent variable: amount of caffeine
• Dependent variable: sleeping hours
• Controlled variables:
-Adults have been on the same sleeping
schedule for weeks.
-Adults have had the same amount of caffeine
their whole lives (to make sure some are not
immune more to it than others)
-Maybe test adults who have the same job!
