Question 4
Nomsa investigated a forest ecosystem for her Natural Sciences project and captured
some woodlice on the forest floor. She investigated if woodlice prefer to live in light
or dark conditions. She designed a choice chamber which is a chamber divided
into difference compartments or sections with a doorway to allow animals to move
between the different conditions. Choice chambers can be used to find out what
conditions some animals prefer by observing the number of animals in each section.
Six woodlice were placed on each side of the choice chamber and observed. The
number of woodlice in each chamber was counted and the results recorded in the
table below.

Question 5
What temperature is ideal for bacterial growth?
36 Petri dishes were filled with the same agar (a growth substance for bacteria).
Bacteria samples of E.coli from a known source were taken and spread evenly
across each plate. Six plates were placed in each of six containers that remained
at constant temperatures of 5°C, 10°C, 15°C, 20°C, 30°C and 40°C. Each container
was left untouched for 36 hours, opened and each plate was checked for the
percentage of bacterial growth.

CAPS summary of Natural Sciences
concepts and content
Hi Natural Sciences students and teachers,
Depending on the choices made by your school, you may cover some of these
concepts and content at different stages of the year (or even in different grades)
in comparison to when they are recommended in the CAPS documents.
What we have provided here is simply a summary of the concepts that you
can expect to see examined in this book as outlined by the CAPS documents
for Grades 8 and 9.
And students, PLEASE make sure to check with your teachers about what
content will be covered in your school's Natural Sciences exams! Just because
it's in this book (or NOT in this book) doesn't mean that it will automatically
be included or excluded from the exams you write at school!
With that said, we hope that you find this resource useful in your revision
for the subject that becomes Life Sciences, Physical Sciences and Geography
in Grades 10, 11 and 12!
