The Key to Keeping the Secret
Day 4
Lesson Objectives
Students will be able to explain at least one modern use of cryptography.
Studetns will be able to describe at least one way that their new cryptosystem has been improved because of collaboration and INTERACTIONS with others.
Point to Ponder
Cryptosystems do not always have to be absolutely secure.
Essential Question
How has technology played a role in changing cryptography?

How to create video on an iPad
For directions on how to use the iPad's camera app, watch the video above from the beginning until the timer reads 2:44. The written directions are below.
1. Find and click on the camera icon on the iPad – the photo screen should open (make sure your
iPad is in landscape when you record.)
2. Slide the column that says video, photo and square to video.
3. The white button should turn to a red button. Press the red button to record. (Make sure the camera is on the
top left corner of the iPad.)
4. The red button should turn into a red square with a white circle around it – you are now recording – press the
button again to stop recording.
5. To view the recording press the square in the bottom right corner.
6. Press play to watch the video.
Below are links to the Padlets for each of our days. Feel free to revisit any or all of these Padlets to be reminded about all the information we, as a class, have collected to help you create your new cryptosystem.
