MULTI-ELEMENTAL ANALYSIS OF EXTRACT FROM PONGAMIAPINNATA

Heavy metals are found to be an important micronutrient for plants, humans, and animals provided the level is within the limit hence it is necessaryto determine its concentration. The extract from the seeds of Pongamia pinnata was derived by acid digestion using H2SO4. The extract was furtherclarified and filtered using standard filter papers. The clarified extract was diluted and the diluted extract was analyzed for the presence of heavymetals such as Zn, Mn, Mg, Fe, and K using atomic absorption spectrometry. The analysis revealed that the concentrations of certain metals were inacceptable levels and concentrations of certain other metals were in unacceptable levels which will have considerable impact on the engine's life andthe environment when the extract from it is used for biodiesel production.Keywords: Pongamia pinnata, Heavy metals, Atomic absorption spectrometry, Impacts, Engine, Environment

Facing up to the challenges of Covid-19 on teaching and learning practice: Use of online debates to enhance engagement and foster authentic learning and assessment

The archived document was an online presentation given at CABS Learning Teaching & Student Experience Conference at 12.00-12.30 on 30 June, 2021.This case study demonstrates how embedding authentic assessment principles within Team Based Learning practice helped to overcome challenges related to synchronous online teaching provision. We discuss how developing a debate culture helped strengthen student engagement and fostered an inclusive learning experience. We also reveal insights from our learners feedback on the experience and on ways to mitigate technology related limitations
