WORKSHEETS
Attention Teachers
1.
KISS Worksheets are designed to consolidate students’ knowledge &
understanding and/or develop or practice a skill, such as graphing,
calculating, reporting prac.work, etc. Some are suitable to issue as
homework assignments. Some can be used as a “quick quiz”.
2.
In both the “PhotoMaster” and “OnScreen” resources,
an information box (as shown) indicates the appropriate
point for each worksheet to be completed.
Please complete
Worksheets 1 & 2
before going on.
3.
KISS Worksheets are formatted for photocopying so that they may be used
as in-class paper exercises, quiz tests or homework assignments.
They can also be converted for use as Microsoft WordTM documents, or
with software allowing annotations, (eg Microsoft OneNoteTM) or apps such
as “Notability”TM and “iAnnotate PDF”TM in tablets & iPads. This allows
KISS Worksheets to be completed by students in their computer, then
submitted by email, for example.
Check our website for downloads about these uses of KISS Worksheets.

To “classify” means to place things into a)............................... with common
features. When classifying living things we use the b)............................. and
functioning of their c)...................... and bodies.
At the highest level, the important criteria are:
• whether the cells have a d).................... or not. Another important cellular
feature is whether or not each cell is surrounded by a e)..................................
• if the organism is made up of 1 cell ( f) “..................................” ) or many cells
(g) “....................................”)
• how the organism gets food. h) “.....................................” make their own
food, while i) “................................” eat food made by other organisms.
The system of classifying was first invented by j).................................... over
200 years ago. He placed all living things into just 2 “Kingdoms”;
k)............................ and l)................................... However, modern technology,
such as the m).................................. microscope, has caused the system to
change. We now recognise at least 5 Kingdoms of life including the Plants,
Animals and also n)................................, o).................................. and
