QUESTION 2 ASSESSMENT STRATEGY 1 1. 2. 3. SUBJECT : Physical Sciences; GRADE : 12; TOPIC : Testing Batteries LEARNING OUTCOME : LO1 and LO2 AND LO 3 ASSESSMENT STANDARDS : AS 1 (recalling and stating specified concepts) AS2 (indicate and explaining relationships) AS 3 (applying scientific knowledge) 4. WHO IS THE ASSESSOR The educator. 5. ASSESSMENT INSTRUMENTS A basic memorandum on the chemical reaction of batteries and the scientific facts will be used, together with a rubric to assess the scientific write up and the practical of testing the batteries. 6. ASSESSMENT CRITERIA Aim of the investigation stated clearly. Procedure to ascertain the difference between the batteries described correctly and logically. Results recorded correctly in a table and graph, and by using equations. Valid conclusion based on the practical experiment. Neatness and general presentation
ASSESSMENT PRODUCTS SUBMITTED BY LEARNER Learners must do research on the different types of batteries available and present their findings in a scientific write up of no less than 10 pages, which must include a contents page and full bibliography. They must perform some sort of experiment (chosen by them) to illustrate the differences between various batteries and the full details of this experiment must be included in the write up, which must be accompanied by tables of
results, graphs and the necessary chemical equations. The write up must also include a discussion on the impact of the disposal of batteries on the environment. 8. LEARNING STYLES, APTITUDE AND INTERESTS I would consider that certain learners would be keener to do the practical experiment of illustrating the...
