Humpty Dumpty is about to fall
and break – can you save him???
His wall is one metre high - your challenge
is to use what you have learned about
materials to design and build a protective
casing to save him from harm when
he lands.
• An egg (pai
nted with a
humpty du
mpty face if time allows)
• A range of
packaging materials e
.g. bubble wra
p, newspaper,

h
protective
floor covering

Humpty must fall
down here.
Approx.
1 metre.

1. Discuss how you will wrap up Humpty Dumpty to keep him safe. He is
going to hit the floor with a bang! Will you use something soft to cushion him, something rigid to keep him safe, a combination of the two or other ideas?
2. Build your chosen design around Humpty.
3. Once you are confident that your packaging will keep Humpty safe during his
fall,
place
him in his
protective
case
at the edge
of table and
a hen
egg
(approx.
5 cm)
and an
ostrich
egg (approx

over onto the floor.
4. Did he survive the fall or does your design need a rethink? Discuss your
results with the rest of your class. Which designs worked best?

An Ostrich egg can reach
35mm across and on average weighs
13kg. It is very strong. A 90kg man
can stand on one without it breaking!
