This document contains workings, explanations and solutions to the PSC1501 Assignment 3 (QUALITY ANSWERS) 2024. For assistance call or us on 0.6.8..8.1.2..0.9.3.4...... QUESTION 1 1. There are several types of practical activities. Demonstrate your understanding of demonstrations, experiments and practical investigations. The information should include the following: • Supplying an example of each practical activity • The role of the learner during each practical activity • The role of the teacher during each practical activity • An important element of each practical activity to consider (20) QUESTION 2 2. Specific aim 1: “Doing Science” states that: Learners should be able to complete investigations, analyse problems and use practical processes and skills in evaluating solutions. This means that learners should plan and do simple investigations and solve problems that need some practical ability. Attitudes and values underpin this ability. Respect for living things is an example – learners should not damage plants; if they examine animals, they should care for them and release them to the place they found them. Practical investigation: • Investigating different soil types – measuring how much water different soils can hold (Grade 5 – term 4). The scientific process is a way of investigating things about the world. Scientists use this process to find out about the world and to solve problems. 4 Follow the steps below to identify and elaborate on them in the investigation above. Step 1: Identify a problem and develop a question. What is it you want to find out? Step 2: Form a hypothesis. A hypothesis is your idea, answer or prediction about what will happen and why. Step 3: Design an activity or experiment. Do something that will help you test your idea or prediction to see if you are right. Step 4: Observe/note changes/reactions (e.g., through measuring), and record your observations (e.g., onto a table). What were the results of your activity or experiment? Write about what happened. Step 5: Make inferences about the observations recorded in the tables, graphs, drawings, and photographs. Make some conclusions. What did you find out? Do your results support your hypothesis? What did you learn from this investigation? Guidance for answering the above question: • Source the practical investigation from a textbook or the internet. • Identify the various steps and supply the relevant information for each step in the practical investigation.

Science teachers use models to demonstrate the relationship between them. In relation to the Moon, design an information sheet/poster or brochure that you can use to educate learners on three different South African cultural or tribal stories about the Moon. Marks will be allocated as follows: • Design and layout of the information sheet/poster or brochure (2) • Pictures of cultures included (3) • Language used in each culture for the Moon (3) • Story for each culture or tribe (3X4=12)
