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 food-growing 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.

Bellringer-August 28, 2013 (Rip-O-Matic Leaf Lab)

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 shade.

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? Explain.

Agenda

• BR (5 min)• Talk about scientific method (10 min)• Lab: Making a Rip-O-Meter (Day 1) (30 min)• ES (5 min)

1. PURPOSE. State or define the problem.2. RESEARCH. Collect information about the problem3. HYPOTHESIS. Proposed explanation of the problem.4. EXPERIMENT. Test your idea and collect data.5. ANALYSIS. Analyze results and review.6. CONCLUSION. Form an answer to the problem.7. (REPEAT)

Scientific Method Steps

Variable = what is changed in the experiment

Control = what is kept the same

Controlled Variables = variables that are being kept the same.

Independent variables = variable being manipulated

Dependent variables = response that is measured

Variables & Data

Example: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!

Exit Slip: August 28, 2013

• Think of 5 different experimental errors that may impact the results of your data in the lab today.

Qualitative vs Quantitative

• qualitative = quality, data is observed not measured

• ex. colors, textures, smells, tastes, appearance, beauty, etc.

• quantitative = quantity, data is measured, numeric

• ex. length, height, area, volume, weight, speed, time, temperature, humidity, sound levels, cost, members, ages, etc.
