Introduction
Top Science 5 Teacher’s Resource Book provides a range of materials
designed to complement the Student’s Book and the Teacher’s Book.
These materials contribute to the flexible nature of Top Science: students
in the same class can be given worksheets at different levels, or weaker
students can complete the tasks with stronger peers. Teachers with more
contact hours can make use of these photocopiable materials
as and when they need them.
There are three categories of worksheets: reinforcement, extension,
and assessment. Use them for revision purposes, for extension
practice, as progress tests, assessment, or for homework.
The worksheets can be photocopied and filed in a folder.
Reinforcement and extension worksheets
There are forty-two reinforcement worksheets. These materials
constitute a flexible tool: they can be worked on after the relevant
section in the Student’s Book, before the Activities sections, or as extra
preparation for the unit assessment. The answer keys are provided.
There are fifteen double-page extension worksheets, one for each unit
of the Student’s Book. These worksheets can be used for fast
finishers or to extend class work. Depending on their level, students
can complete the worksheets with or without consulting their Student’s
Book or other sources. The answer keys are provided.

The Earth’s crust

Name

Name
The Earth’s crust is made up of rocks. Over time, these rocks wear down and break apart.
Soil is made up of the remains of rocks and of living things.
Date
These groups of stars are constellations. And of
all the constellations, there is one that is easily
recognised by everyone: the Big Dipper, also known
as Ursa Major or the Big Bear.
The Earth’s crust is continually changing because of erosion, transport and deposition,
and sedimentation.
The Big Dipper is located in the northern
hemisphere. It is made up of seven stars. Three
of these stars seem to form the handle and four
appear to form the bowl of a dipper, another name
for a ladle or scoop.
Match.
The rock breaks apart.
Water enters cracks in the rock
and freezes.
EXTENSION
Scorpions and dragons, princesses and hunters,
chariots and arrows... If you look up at the sky on
a clear night, from a place without pollution, you
will see hundreds of stars that form outlines of
interesting shapes.
Remember

Star gazing
URSA MINOR
URSA MAJOR
The star at the end of the handle of the Little
Dipper is the North Star, also known as Polaris or
the Pole Star. Another way to find the North Star is
to draw a line through the last two stars of the bowl
of the Big Dipper. This line will point to the North
Star.
When water freezes,
it expands.
◾ Now, explain how water causes rocks to break down.
Close by is the constellation of Cepheus, which represents the legendary king of Ethiopia, Cefeo.
Beyond Cepheus you can see Cassiopeia, which will look like an M or W, depending on the season.
Winter is the best time of year to see the constellations Orion, the hunter, and Canis Major, the dog
which followed Orion.
In total, there are 88 constellations.

Number these processes in the correct order.
Wind carries the eroded material.
Wind and water erode a mountain.
Read and answer.
What is a constellation?
The material settles at the foot of another mountain.

What constellation does the Pole Star belong to? In what hemisphere is it?
Rivers and streams
Wind
Seawater

Organs form systems which work together to carry out a common function.

Plants can be classified into two main groups: non-flowering and flowering.
Non-flowering plants do not produce flowers, seeds or fruit. They reproduce with spores. There

Flowering plants produce flowers and seeds in order to reproduce. There are two main groups:
gymnosperms and angiosperms. Gymnosperms do not produce fruit. The seeds are grouped
together in cones. Angiosperms produce fruit with seeds inside.

Photosynthesis is a complex chemical process. It enables plants to manufacture food from
water, mineral salts, carbon dioxide and sunlight.
Chlorophyll is a green substance which traps sunlight. It is found in special organelles called
chloroplasts inside plant cells.
Plants release oxygen as a waste product of photosynthesis.

Sexual reproduction in plants
Name
Reinforcement
Date
Remember
Flowers are the reproductive organs of plants. They have male parts and female parts.
Stamens are the male parts of the flower. Pollen is produced in the anther. The pistil is the
female part. It contains the ovary, which contains ovules. Ovules become seeds.
Pollination is the transfer of pollen from the stamen to the ovary within the same plant or
between plants of the same type. After pollination, seeds and fruit begin to grow.
1
Label the parts of the flower.
2
Write T (true) or F (false). Then, write the correct sentences.
Plants that use wind pollination produce very small quantities of pollen.
The stamen and pistil are protected by the corolla and the calyx.
Plants that use insect pollination have small, unattractive flowers.

Asexual reproduction in plants
Name

Remember
Many plants can reproduce without flowers or seeds. This is called asexual reproduction. These
plants use parts of themselves to reproduce.
Tubers are subterranean stems. Part of the stem grows above the ground and develops
leaves. Part grows underground and develops roots.
Rhizomes are specialised stems. They extend horizontally below the ground.
Stolons are specialised stems which extend horizontally above the ground from the mother plant.

type of rocks, fossils can be found.
Metamorphic rocks are formed when heat or pressure changes the original rocks.
Metamorphic means ‘change’.
