An overview of the relationship between educational research and teaching chemistry is presented, covering the opportunity areas between production and science popularization (dissemination of scientific knowledge). Knowledge apprehension and appropriation are also discussed in the educational context of UNAM, in Facultad de Estudios SuperioresCuautitlán. Links between scientific and pedagogical training are defined by considering educational research as a means to broaden the theoretical and methodological options for chemistry teaching.

Mustard plant is one of a potentially great horticultural crops are to be developed. Although generally cultivated mustard plants on the plateau, but there are varieties that can adapt, developed and high production in the lowlands as long as the grant of the right fertilizer. The purpose of this research was: 1) to know the influence of the type of fertilizer and planting distance towards the growth and development of plant mustard greens.

Trematode infection is a prevalent parasitic disease of livestock that causes one of the major problems leading to a huge economic loss in livestock production. The cross sectional study was conducted from October 2015 to June 2016 at Lemo Woreda and Hossana Town to determine the infection rate, predominant trematode species, fluke burden and severity of liver pathological lesions of sheep slaughtered at Hossana Town, and to assess the direct economic loss due to liver condemnation.

Mustard plants including one type of vegetable leaf that has many benefits in people's lives day to day, so the demand for these commodities is enormous. The type of these vegetables are preferred by the rest of the community that low-income to high-income, patcoy mustard plant so that it takes a relatively high amounts of and continuous improvement. Planting mustard plants in the lowlands on the mineral soil was made one of the alternatives for increasing production plant mustard greens. Mineral soils are less fertile cultivated mustard plants if it will need to give material manure.

Celery is a vegetable plant grass-shaped spice used as food seasoning and efficacious medicine that lowers high blood pressure, treat hair loss, coping difficult sleep, improve waste water art and strengthen sinew. In terms of its benefits then to get the celery is high and good quality, besides observing the ideal growing, plants also require maintenance, such as the supply of nutrient elements and plants should continue to get sufficient nutrient elements during its growth.

This study was conducted to determine the species composition, frequency and total density of seaweeds found on the island of Nusalaut. There were 33 species of seaweed. Of the 33 species, 15 were from the class of Chlorophyceae (45.5%), 10 species from Rhodophyceae (30.3%), and 9 species from Phaeophyceae (27.3%).Total frequency showed the highest Gracilaria (Rhodopyceae) of 29.63% in Akoon and Titawaii is 20.34%, while Halimeda (Chloropyceae) of 19.60% found on the Nalahia. Highest total frequency Phaeophyceae (Padina) is 12.96% found on the Akoon.

A pot experiment was conducted during 2017-2018 to examine sprouting and growth responses of ixora stem cutting types of and ixora varieties. The cutting 4-6 inches in length of two ixora varieties viz. S.Yellow and N.Grant were taken from well grown plants of ixora. The cuttings included terminal and sub-terminal stem cuttings. The cuttings types viz. C1-Terminal cuttings with two leaves, C2-Terminal cuttings with four leaves, C3-Sub-terminal stem cuttings with two leaves and C4-Sub-terminal stem cuttings with four leaves.

Scholars often lament that urban areas in post-apartheid South Africa are beset by a shortage of affordable urban residential land and informal settlements. This shortage will never be addressed through market-based land reforms. The redistribution process is criticised for being slow and ineffective; the state cannot afford to purchase urban land at the high prices demanded by landowners and the scale of support needed to deliver land to the majority who are poor is not fiscally sustainable.

Along with government and non-government parties, Self-Help Groups (SHGs) are working towards achieving the goal.

The limitations of the media grows and diversity of commodities in a narrow area, resulting in the production of the plant is not optimal and not sustainable. The limitations of the media in the form of planting land can be anticipated by utilizing organic ingredients from the results of the activities performed by the public. An alternative workaround is to search for materials in addition to ground and without the need for extensive land to farm.
