Awareness as a broad term is subject of many scientific disciplines such as psychology, education and biology etc. Thus the awareness study about our surrounding and environment can be called as a socio-scientific issues. The human species are often in interaction with almost all living and non-living things in the world. And we are not aware about these to some extent. The awareness changes according to the same variables such as mobility, color contrast and similarity to the human being. The living groups (plants and animals) come first rather than non-livings such as stones, water and air. It is the clear that people have higher awareness towards animals. Against plants and mushroom, the awareness is well below the desired level. In this study, it was tried to determine the changes in middle school students' awareness towards animals, plants and mushrooms through nature education. Nature education connects individual with nature. During the education, students recognize livings in the nature and try to understand the importance of nature for a sustainable future. Within the scope of the study, 47 secondary school students were given one week of natural education. Students' answers were analyzed statistically. The pictorial information scales applied before and after the education reveal a significant increase in plant awareness, especially in a world where plant blindness is high.

The aim of this study is to introduce an attitude scale in order to define students? attitudes about environment, recycling, plastics, plastic waste. In this study, 80 attitude sentences according to 5-point Likert-type scale were prepared and applied to 492 students of 6th grade in the Kastamonu city center of Turkey. The scale consists of cognitive, affective, and psychomotor skills domains. After the factor analysis it was found that they have 3, 4 and 5 factors accordingly. After the reliability analysis the alpha values for cognitive, affective and psychomotor scales are 0.854, 0.871 and 0.826 respectively. As a result, it is found that the scale can be used to define cognitive, affective and psychomotor attitudes.

The scale consists of cognitive, affective, and psychomotor skills domains. After the factor analysis it was found that they have 3, 4 and 5 factors accordingly. After the reliability analysis the alpha values for cognitive, affective and psychomotor scales are .854, .871 and .826 respectively. As a result, it is found that the scale can be used to define cognitive, affective and psychomotor attitudes. [ABSTRACT FROM AUTHOR]

Gold (Au) and silver (Ag) nanostructures have widespread utilization from biomedicine to materials science. Therefore, their synthesis with control of their morphology and surface chemistry have been among the hot topics over the last decades. Here, we introduce a new approach relying on sugar derivatives that work as reducing, stabilizing, and capping agents in the synthesis of Au and Ag nanostructures. These sugar derivatives are utilized alone and as mixture, resulting in spherical, spheroid, trigonal, polygonic, and star-like morphologies. The synthesis approach was further tested in the presence of acetate and dimethylamine as size- and shape-directing agents. With the use of transmission electron microscopy (TEM), selected area electron diffraction (SAED), x-ray diffraction (XRD), scanning electron microscopy (SEM), and ultraviolet-visible (UV-vis) absorption spectroscopy techniques, the particle size, shape, assembly, aggregation, and film formation characteristics were evaluated. NPs' attributes were shown to be tunable by manipulating the sugar ligand selection and sugar ligand/metal-ion ratio. For instance, with an imine side group and changing the sugar moiety from cellobiose to lactose, the morphology of the Ag nanoparticles (NPs) transformed from well dispersed cubic to rough and aggregated. The introduction of acetate and dimethylamine further extended the growth pattern and morphological properties of these NPs. As examples, L5 AS, G5AS, and S5AS ligands formed spherical or sheet-like structures when used alone, which upon the use of these additives transformed into larger multicore and rough NPs, revealing their significant effect on the NP morphology. Selected samples were tested for their stability against protein corona formation and ionic strength, where a high chemical stability and resistance to protein coating were observed. The findings show a promising, benign approach for the synthesis of shape- and size-directed Au and Ag nanostructures, along with a selection of the chemistry of carbohydrate-derivatives that can open new windows for their applications.
