PSC1501 Assignment 3 2024 | Due 5 July 2024

Description

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.

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.
