DRAFT 1 Lesson Title: Easy Hydroponics Grade Level: 9-12 Subject Area: Science – Biology/Chemistry Setting: Classroom or Greenhouse if available Instructional Time: Several Class Periods Grade Level Expectation (s): B1.1A Generate new questions that can be investigated in the laboratory or field. B1.1B Evaluate the uncertainties or validity of scientific conclusions using an understanding of sources of measurement error, the challenges of controlling variables, accuracy of data analysis, logic of argument, logic of experimental design, and/or the dependence on underlying assumptions. B2.3B Describe how the maintenance of a relatively stable internal environment is required for the continuation of life. B2.3C Explain how stability is challenged by changing physical, chemical, and environmental conditions as well as the presence of disease agents. B2.5C Describe how energy is transferred and transformed from the Sun to energy-rich molecules during photosynthesis. B3.1A Describe how organisms acquire energy directly or indirectly from sunlight. B3.1B Illustrate and describe the energy conversions that occur during photosynthesis and respiration.

greenhouse tomatoes in low-tech non-circulating water culture

Additional index words. Lycopersicon esculentum, homeowner application, temperature, passive hydroponics. Abstract. Greenhouse tomatoes (Lycopersicon esculentum Mill.) were grown in a glass greenhouse at the Seminole Com munity College Horticultural Unit in Sanford, FL for two grow ing seasons (1996-97,1997-98) to determine the feasibility of a passive non-circulating, low-tech water culture system. Water and nutrients were added to troughs lined with 6-mil poly and covered by 4' x 8' insulation panels. Tomatoes in 4" azalea pots were placed in holes on the panels so that the bottom of the pots barely touched the water. An air space was maintained below the panel. Marketable yields during 13 weeks of harvest averaged 13.6 lbs. per plant the 1st season and 9.4 lbs. per plant the 2nd season. Marketable yields and plant vigor de clined when daytime greenhouse temperatures were consis tently over 90 F in June of 1997 and May of 1998. No significant yield differences were found between tomato cvs. Trust and Match. Suspending a screen in the water for root attachment did not significantly affect yields. The simple system design and maintenance makes it suitable for homeowner, hobbyist, or school demonstration applications provided that ideal tem peratures for greenhouse tomatoes can be maintained. Introduction New passive hydroponic systems were developed at the Asian Vegetable Research Center in Taiwan (Anon., xxxx) and studied further by B.A. Kratky and colleagues at the Uni versity of Hawaii (Kratky et al., 1988; Kratky, 1993; Kratky, 1996). These systems are low tech and relatively inexpensive compared to traditional hydroponics. Preliminary work in Florida (Fedunak and Tyson, 1997) found that short season lettuce crops performed well in a passive hydroponic system.

Kids and the Gluten-Free Diet - School of Medicine

The gluten-free diet presents unique challenges for children with celiac disease and their families. Prior to diagnosis, children may be quite ill, suffering from poor growth and developmental delay. Upon accurate diagnosis and treatment, children usually improve quickly; however despite rapid improvement of symptoms, compliance with diet may be less than optimal, putting the child once again at risk for the complications of untreated celiac disease. Because children may feel uncomfortable being singled out as “different,” a diet that calls attention to their condition, and thus their differences, presents a unique challenge to parents and caregivers trying to meet the treatment guidelines. Frequent follow-up and monitoring, along with educational resources and support groups can aid families in maintaining a gluten-free diet and provide creative ways to deal with the challenges inherent in a gluten-free lifestyle.
