WALT: Recognise that they need light in order to see things and that
dark is the absence of light.
Are these objects light sources? Make a for Yes or for No.
Is a window a light source? Explain your answer
What is dark?
For each sentence bellow, write True or False in the box next to it.
Most electric lights are brighter than the sun.
Candles are electric lights.
A torch is a light source
4
WALT: Notice that light is reflected from surfaces.
Fill in the blank space in this sentence:
Light travels in a line from a light source to an object.
Write 'shiny' or ‘not shiny’ under the correct pictures.
What happens if you shine a torch on a shiny surface?
5
WALT: Recognise that light from the sun can be dangerous and that
there are ways to protect their eyes.
Why should you never directly look at the sun?
Think about protecting yourself from the sun. What can you do to
protect these things?
a) Your eyes:
b) Your sun:
WALT: Recognise that shadows are formed when the light from a light
source is blocked by a solid object.
Join up these words to the correct explanations.
6
Explain how a shadow is formed.
WALT: Find patterns in the way that the size of shadows change.
Look at the position of the sun in each picture and draw the shadow of
the tree.
7
WALT: Identify and describe the functions of different parts of
flowering plants: roots, stem/trunk, leaves and flower.
Label the main parts of the plant.
What are the functions of the following parts of a plant. Write your
answers in the space provided. Some parts have MORE THAN ONE
function, list them all.
STEM
ROOT
LEAF
FLOWER
8
WALT: Explore the requirements of plants for life and growth (air,
light, water, nutrients from soil, and room to grow) and how they vary
from plant to plant.
Write three things that plants need to live and grow.
1. __________________________
2. __________________________
3. __________________________
Do plants need food to grow? Yes or No
Do plants need space to grow? Yes or No
Tom and Saad both grow plants. Tom grows his plant on the window
ledge and Saad grows his plant in the cupboard. Which plant do you
think will grow most healthy?
Tom’s plant Saad’s plant
Why?
________________________________________________________
________________________________________________________
What did Saad’s plant not have?
________________________________________________________
Order the life cycle of the bean, using numbers 1-4.
9
WALT: Explore the part that flowers play in the life cycle of flowering
plants, including pollination, seed formation and seed dispersal.
1. Label the different parts of a flower.
2. Label each part of the life cycle of a plant.
An apple tree life cycle has six stages.
Seed, seedling, adult tree, buds, flowers, fruit
10
WALT: Compare how things move on different surfaces
Look at the table below and answer the questions below.
Which surface did the car move the furthest on?
Which surface did the car move the least on?
Why do you think it can move further on some surfaces and not others?
Surface Distance
Concrete 2m 45cm
Grass 1m
Carpet 1m 80cm
11
WALT: Identifying differences, similarities or changes related to
simple scientific ideas and processes.
Use the venn diagram to show the differences and similarities with
magnetic materials.
*Which objects are made of metal
*How do you know?
*Which objects are magnetic?
*Are all metal magnetic?

WALT: Describe magnets as having two poles
Look at the diagrams. Then draw a ring around the correct word, ‘attract’ or
‘repel’.

WALT - Predict whether two magnets will attract or repel each other,
depending on which poles are facing.
Complete the sentences using the word bank below.
Magnets have two ___________ One is called the ____________ pole and
the other is the ___________ pole. When opposite poles are near one
another, they ___________ together. This means the two poles
__________. When two of the same poles are near one another, they
___________ away from one another. This means the two poles
___________ each other.
Word bank:
repel north attract south pull push poles
Draw arrows to show what force happens in these pictures.
14
WALT - Notice that some forces need contact between two objects,
but magnetic forces can act at a distance
1. The force that pushes 2 magnets apart is
a. attraction
b. gravity
c. repulsion
2. Do magnets need to be touching to
attract or repel each other?
Yes / No
3. Can you explain why you chose your above answer?
4. Is it possible to push an object without the two objects touching?
Yes / No because ___________

15
WALT - Observe how magnets attract or repel each other and attract
some materials and not others
1.The force that pulls 2 magnets towards each other is
a. friction
b. attraction
c. repulsion
2. When the north pole of one magnet is placed next to the north pole
of another magnet they
a. repel
b. do nothing
c. attract
3. When the north pole of one magnet is placed next to the south pole
of another magnet they
a. do nothing
b. repel
c. attract
4. Which of these is the only magnetic material?
a. plastic
b. steel
c. wood
5. Write whether these magnets will attract or repel:
16
WALT - Compare and group together a variety of everyday materials
on the basis of whether they are attracted to a magnet, and identify
some magnetic materials
Colour the faces to show if these objects are magnetic or not.
What do the magnet materials above all have in common?
