Health and Wellness Health – Future of society
Impact Economic Psychological Physiological Wellness – Encompasses much more than physical health! Physical, Social, Emotional, Intellectual, Occupational, and Spiritual, Increasingly popular trend of words as it relates to children
4
Health & Wellness Mindfulness Health Consciousness
The quality or state of being conscious or aware of something Mental state achieved by focusing on awareness of the present moment Accepting feelings, thoughts, and bodily sensations Typically used as therapeutic technique Health Consciousness The awareness of one’s health
5
“Growing” Literature tells us Growing impacts Health outcomes
Health mindfulness Energy intake vs expenditure (nutrition) Physical activity levels
6
Aquaponics Activities
Ways to incorporate the aquaponics growing system into the classroom
7
What is Aquaponics
8
Hydroponics Benefit Versatile growing locations
Sterile and controlled environment. Crops grow two times faster than soil gardening Recirculating system hydroponicsgrower.org
9
Hydroponics Benefit Little space… Not a problem
10
Hydroponics Cost Need to add nutrients industrial fertilizers Large amount of fresh water needed (Blidariu et al 2011). Economic problems: Hydroponics systems cost more to start up and maintain. Limited to the high cash crops. Tomato's Small error or miss calculation in any one element can mean a big loss in profit (Benton 1982
12
Aquaculture Benefits Aquaculture accounts for more than $100 million in revenue in the mollusk industry alone (Food and agricultural 1998). Farmed fish and shellfish has more than doubled in the past 15 years (Naylor 2000). Aquaculture can be Made in many areas.
13
Aquaculture Cost Land-based aquaculture systems like hatcheries often require huge amounts of water to be pumped into their systems. High amounts of ammonia, nitrates and nitrites produced as waste (Benton 1982).
14
Aquaculture Cost Farming carnivorous species requires large inputs of wild fish for feed. Reduce wild fish abundance: Habitat modification, Wild seed stock collection Disease ecological impacts (Naylor 2000). Pollution Number one vector for aquatic invasive species (Welcomme 1992; Dextrase et al.1999). In the 1970’s bighead and silver carp (Chick 2001). A parasitic worm from South Africa was introduced into California in the 1980’sand had detrimental effect on abalone. (Kuris and culver 1999).
15
What is Aquaponics Aquaponics is the combination of Hydroponics and Aquaculture: growing of fish and plants together in a closed recirculating system. The water from the fish tanks is filtered through media (gravel, sand, ect.) that house bacteria. The bacteria in turn break down the fish waste to nitrate and nitrite which is then transported via water to the agricultural produce (Nichols et al 2012). tucsonap.org
16
Aquaponics Benefits Take the cost of aquaculture fish waste now is used to feed plants Take the cost hydro needing lots fertilizer Now the benefits of both aquaculture and hydroponic can be found in aquaponics VERY SUSTAINABLE Ultimately aquaponics will aid in conservation and holds great promise in sustainability
17
Aquaponics Benefits in sustainability
Increasing food security (Carney 2001) Decreasing food deserts in urban (McClintock 2011) and rural areas (Mohamad et al. 2013) Improve environmental performance, as it can decrease the distance food has to travel, decrease the amount of food wasted (McClintock 2010; Smith et al. 2013). Increase community and economic development by increasing profitability, diversifying revenue streams and bringing in alternative business models (Goodman 2011).
18
Aquaponics Benefits Nutrient recycling from the fish wastewater
This study found that an aquaponics system can remove up to 69% of nitrogen from that particular system (Garber and Junge 2009). Produce edible fruits. Lekang 1999: Compared different tomato varieties in aquaponics and conventional hydroponics and found that the four varieties of tomatoes had higher fruit yields in an aquaponics system (Lekang 1999). Wegner 2003: Showed that all varieties of tomatoes yielded more fruit in an aquaponics system than in both the soil culture and hydroponics system (Wegner 2003).

Curriculum Ecosystem Bacteria Nutrient flow Energy flow
Water chemistry ?
27
Intro to Seeds Objectives: Students will identify the parts of a seed
Students will compare seeds and organs of different plants
28
Intro to Seeds Materials: Activity: Spoon
Various fruits, vegetables, herbs Activity: Observe and compare plants in aquaponics system In groups, dissect and compare seeds of various plants
29
Germination Objectives: Learn different ways to grow seeds
Learn what plants need to grow Compare sprouting process of different seeds Compare roots of different plants
30
Germination Materials: Activity: Seed types -- Ziploc bags
Coconut fiber Paper towels water Activity: Split seeds: aquaponics system, coconut fiber, and wet paper towel in Ziploc bag Observe the differences in growing methods over time Transplant sprouted seeds to system and continue monitoring differences
31
Scientific Method Objectives: Expand upon germination lesson
Introduce the process of asking and testing questions
32
Scientific Method Materials: Activity:
Seeds planted in germination lesson Activity: Have students think of a question Students write hypothesis for their question Students observe plants on daily basis and record observations
33
Ecosystem Objectives:
Students will understand there are different ecosystems Students will define abiotic and biotic factors within ecosystem
34
Ecosystem Materials: Activity: Hat with paper of each ecosystem on it
Define ecosystem and discuss main types Discuss abiotic (non-living) and biotic (living) factors In groups, pick an ecosystem type out of a hat
35
Ecosystem Activity continued:
Have groups list all the factors in their ecosystem Each student will play a different role (factor) in their ecosystem, write 2-3 statements about their role, and how it affects ecosystem Groups will present ecosystem, each factor expressing how it relates to the system
36
Animal Behavior Objectives: Students will define animal behavior
Students will observe basic fish behavior Students will understand what an ethogram is and its use in observing animals
37
Animal Behavior I Materials: Activity: Paper
Define animal behavior and discuss behavior they know of common animals Observe fish and notice behaviors Create table of behaviors (ethogram) and help students define each behavior
38
Example Ethogram Behavior Definition Swimming
Fish is using body to move further than body length Resting Lying still at bottom or side of tank Active Fish is moving some, but not enough to be swimming
39
Nutrition Objectives:
Students will compare the factors for survival between plants and animals Students will define nutrition Students will understand the food groups and how each food effects the body
40
Nutrition Materials: Activity: None
Define the food groups and how they effect the body Identify the food components of the system In groups, imagine a meal they could create using the system Identify food group’s and effects on body Can affect the body physically, mentally, emotionally. Have students give examples of their favorite foods and discuss as a class how they might make them feel. Discuss what is missing from the aquaponics system to create a meal.
