Learning intention
We are learning about printing technologies in the past.
Success criteria
We can compare and contrast objects from the past and the present.
We can make inferences and draw conclusions using images and objects as evidence.
Rubber stamps - Compare and contrast
Rubber stamps - Compare and contrast
From the 1940s, rubber stamps were used at school. There were stamps of maps, numbers and clock faces.
Look at the rubber stamps below:

Do you remember printing the map on the jelly pad at the NSW Schoolhouse Museum?
How do you think that is different from your teachers using a photocopier?

After reviewing the various printing technologies, play this game as a concluding activity.
Instructions:
Divide the room into two sides, left and right. Students all stand in the middle.
Ask the students questions, using the ones below as a guide.
The students should decide their answer and move to that side.
Ask a couple of students to explain their reasoning.
Which would use more electricity? A printer (left) or a jelly pad (right)?
Which would be more expensive? A rubber stamp (left) or a photocopier (right)?
Which would be faster to make copies? A photocopier (left) or a hand duplicator (right)?
Which is more likely to break down and need repairs? A printer (left) or a rubber stamp (right)?
