ASSIGNMENT 03 (100 marks)
QUESTION 1
1. 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 investigations:
x Investigating different soil types – measuring how much water different soils can
hold (Grade 5 – term 4).
x Investigating different materials in an electric circuit to see if they are conductors or
insulators (Grade 6 – term 3)
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.
Part A:
Follow the steps below to identify and elaborate on them in the two investigations
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 were 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.
