FORCED TO MOVE
Lesson 1
Lesson plan
Introduction:
1. Divide students into pairs and give each pair a balloon. Students work together to move the
balloon in as many different ways as they can. Prompt students by asking, How can you move your
balloon from one partner to another? How can you move your balloon up into the air? How can you
move your balloon down to the ground? How can you move your balloon from the floor to your
waist? How can you move the balloon from the air to your waist? Students record each way they
moved the balloon on a seperate sticky note and place each sticky note on their desk. QP PC

2. After five minutes, stop the class and ask students to sort their sticky notes into two groups—push
or pull (including gravity). Students fold a piece of A3 paper in half and label each half with either
‘push’ or ‘pull’. Students attach the sorted sticky notes to each section to show examples of pushes
and pulls. Students compare the examples in each section to answer What is a push? and What is a
pull? QP PC PA
Development:
3. View the online video Gravity, force and work at . This video briefly
explains how objects move when a person pushes or pulls them and how gravity acts on objects to
pull them to the ground.
4. Divide the class into groups of four and give each group a ball of playdough, four counters, four
rulers and a copy of the pre-prepared cards on page 116. Ask one student to divide the playdough
into quarters and give each student a piece of playdough, a ruler and a counter. Each student
will need to break off a small amount of playdough to attach the counter to the desk so that the
counter doesn’t move. As a group, students read the instructions on the first challenge card on
page 116 and individually carry out the experiment. Note: Students must ensure they do not touch
their playdough after the action has been performed. As a group, students discuss which type of
force they applied to their playdough and compare what happened to each student’s playdough
when force was applied. Students record a group answer for each question on the challenge card.
Note: Students should tick all the changes that occured to the playdough when answering
question 2. Using a digital camera or iPad®, students take a photograph of the card and the four
pieces of playdough in their changed position, shape or size. Students collect their piece of
playdough and repeat the process for the remaining challenges. PC PA E C
Differentiation
• Less capable students may be grouped together and assisted by an adult to read and discuss
each challenge card.
• More capable students may be encouraged to identify and test other ways they can use force to
change the position, direction, shape or size of an object.
5. If time allows, students should be encouraged to upload their digital photographs to a computer,
resize them and insert all four photographs into a computer program, such as Microsoft® Word or
PowerPoint, to create a poster. Students type their names onto the poster and print it.

Reflection:
6. As a class, test students’ knowledge of forces using the Forces quiz at . Read the question aloud to the class and allow time for students to think about their
answer. Note: The quiz creator website will ask you to join. On the right-hand side, click ‘Start without
an account’. Alternatively, give each student a copy of page 117 to complete a hard copy version of
the quiz. PA C
