Sending photos without WhatsApp
Area
Mathematics
Age
10 to 12 years
Duration
60 min.
Participants
30 to 35 girls
WHAT IT IS ABOUT
Discover how an image travels using zeros and ones.
In this activity, the girls explore how it is possible to send photos from one place to another through a mobile phone. Starting from the game Guess Who?, they discover strategies to ask better questions and reduce options more efficiently. Then, they relate that process to the digital transmission of images, understanding how a photo can be transformed into binary information that a computer can interpret.
- Play Guess Who?
- Create yes or no questions.
- Look for strategies to win better.
- Discover what a bit is.
- Understand how images are sent.
- What a winning strategy is.
- How to ask better questions.
- What the binary system is.
- How an image is converted into data.
- How photos travel digitally.
