Abstract: Endosulfan is a man made insecticide which is highly controversial agrochemical due to its acute toxicity potential for bioaccumulation but still used in large scale in India even though it is being phased out globally. Endosulfan plays a great role in alteration of Hematological status of human beings. The present study was carried out to investigate the acute effects of endosulfan on Hematological parameters such as Erythrocyte count (RBC), Leucocyte count (WBC), percent Hemoglobin (Hb%), Packed cell volume (PCV%) and Mean Corpuscular Volume (MCV) on swiss albino mice. Adult male mice was segregated into four groups, each group with 6 animals. Group I, served as the control was administered with distilled water @0.1 ml/10gb.w; Group II, received endosulfan @3mg/kg b.w; Group III, concomitantly received Phyllanthus emblica; Group IV, concomitantly received Withania somnifera (Ashwagandha) 150 mg/kg b.w along with endosulfan through oral gavaging. All the treatments were continued for 3 months. The toxic effects observed upon endosulfan treatment include Erythrocyte count (RBC) gradually decreased, Leucocyte count (WBC) increased, percent Hemoglobin (Hb%) significantly decreased, Packed cell volume (PCV%) reduced significantly and Mean Corpuscular Volume (MCV) significantly increased. On contrast, treatment of extract of Phyllanthus emblica and Withania somnifera was found to alleviate the toxic consequences of endosulfan, thereby producing ameliorative effect.Abstract: Endosulfan is a man made insecticide which is highly controversial agrochemical due to its acute toxicity potential for bioaccumulation but still used in large scale in India even though it is being phased out globally.

Abstract: The study assessed the relationship between biology teachers' level of creativity and academic performance of secondary school students in Anambra state. Creativity in biology education relates to the processes and particularly the personal and thinking skills that children can develop which will support deep levels of learning. It is the tendency to generate or recognize ideas, alternatives, or possibilities that may be useful. Two research questions were answered using correlation coefficient, arithmetic mean, standard deviation and one null hypothesis tested using one-way ANOVA at 0.05 level of significance. The study adopted a correlational survey design. A purposive sampling technique was used to select 77 biology teachers from 21 public schools Awka Education Zone of Anambra State, Nigeria. Biology Teachers Level of Creativity in teaching Biology (BTLCTB) was the instrument for data collection. The instrument was validated by experts and reliability was established at 0.93 using Cronbach's Alpha. Result of the findings revealed that the level of creativity of a biology teacher determines how effectively he/she teach, the ability to produce original materials, flexibility in teaching, quality of ideas and adequate elaboration in the classroom with innovative skills and strategy shows the level of creativity of a biology teacher, and biology teachers with these qualities are classified as teachers with high level of creativity. Recommendations among others is that biology teachers should be encouraged to be creative in classroom, as their level of creativity will not only make their lesson interesting, but will also motivate the students for better performance.Abstract: The study assessed the relationship between biology teachers' level of creativity and academic performance of secondary school students in Anambra state.
