I will begin
with the children's own lives and remind them that we need energy
for everything we do. Children are asked where this energy comes
from. I will show the children a display of some simple machines/or
pictures of machines, including toys, computer, television, radio,
discuss their uses and what makes them work, e.g. a kettle needs
to be plugged in to provide electricity to make it work.
We will discuss
how energy can make sound, and light. It can make things move, and
make things hot or cold. Examples: Fridge, Television, Radio, Iron
etc. We will talk about other important machines in the home and
how they work. (They will observe pictures of these.)
Laptop and Data Projector are then set up and CD Rom 'The Way Things
Work' inserted. Allow it to load and children watch/listen to introduction.
Then we will
go to the 'Warehouse of Inventions'. Click on 'The Mammoth' to go
further into this warehouse.
I will then
get a child to click on a specific machine e.g. invention. If we
click on the light switch a piece of text and more complex diagram
will come up on screen. It will allow us to explore the scientific
principles behind the machine. Simple machines to look at with class
(on this CD) are:
(iii) hot air balloon
will observe the machines and how they work. We will discuss the
importance of these.
the lesson children complete an activity in their 'Look Around'
books - page 20. They will sort toys and machines, into groups,
which are worked by batteries, electricity, pushed, and pulled.
