Objective: 
Course objectives: 
This course will enable the students to – 
1. Design and conduct experiments, using a broad variety of experimental techniques, and interpret the data obtained to draw conclusions about whether the results do or do not support a hypothesis being tested and whether the experimental design was appropriate. 
2. Work collaboratively with other students and with faculty, understanding that most scientific knowledge/conclusions draw(s) on multiple sources of data and multiple experimental approaches. 
3. Learn “best approaches” for conducting experiments including laboratory safety, data  replication and quality control, record keeping, and other aspects of “responsible conduct  of research”. 
4. Gain familiarity with an area of science such that the students can present their work to  a professional audience and also discuss their work with a general audience.

CO:211 Illustrate different laboratory specimens based on  their external features and  appearance and their categorical  relation with various phylum.

CO:212 Enhance their knowledge  about different mitotic stages by  preparing temporary slides of the  onion root tip and visualizing the  stages of mitosis and meiosis by their key features and demonstrate bar body in buccal epithelial cells.

CO:213 Perform various qualitative and quantitative biochemical techniques to 

differentiate  biomolecules based on their  physical and chemical properties and analyze the effect of  temperature on the enzymatic activity of salivary amylase and liver catalase.

CO:214 Assess taxonomic biodiversity in various habitats and estimate gene frequency in populations using Hardy Weinberg law and differentiate between various phytoplanktons and zooplanktons

CO:215 Demonstrate skills and record the concepts in the form of  practical file and reflect on personal learning experiences and experimental outcomes during viva voce.

CO:216 Contribute effectively in course-specific interaction.
