Use conditions to lock or unlock the door of a safe deposit box.
- Read through the pupil material in the LEGO® Education SPIKE™ App.
2. Engage (5 Min.)
- Use the ideas in the Ignite a Discussion section below to engage your pupils in a discussion relating to this lesson.
- Use the video to explain the lesson.
3. Explore (20 Min.)
- Have your pupils work in pairs to build the build the safe deposit box.
- Ask them to play the program in order to see how the lock works.
4. Explain (5 Min.)
- Facilitate a discussion about how adding conditions can make the safe deposit box even more secure.
5. Elaborate (15 Min.)
- Ask your pupils to make their safe deposit boxes even more secure by adding more conditions to their programs.
- Don't forget to leave some time for tidying up.
- Give feedback on each pupil's performance.
- In order to simplify the process, you can use the assessment rubrics that have been provided.
Start a discussion about iteration or fixing things by asking relevant questions. Here are some suggestions:
- Can someone give an example of a safety device?
- What makes a password strong or weak?
- What's a condition?
Have your pupils watch this video to see what they're about to do.
Split each team's building tasks in order to ensure that everyone is actively involved.
- Pupil A: Safe Deposit Box Door
- Pupil B: Safe Deposit Box Box
Now we’re ready for the next lesson!
This model is also used as the base model for the next lesson, ‘Keep It Really Safe’. That's why there's a motor that isn't being used in this model. The motor's wire is clipped to the back of this version of the model.
This model has a manual key that can be used to unlock the door if needed.
Simplify this lesson by:
- Using the Dashboard to explain to your pupils how many degrees the motor has been turned. (You can find more information about the Dashboard in the Help Section of the SPIKE App.)
Take this lesson to the next level by:
- Having your pupils modify the Light Matrix and sound file to customise their safe deposit box
- Asking each team to modify their program and challenge another team to unlock their safe deposit box
Teacher Observation Checklist
Establish a scale that suits your needs, for example:
- Partially accomplished
- Fully accomplished
Use the following success criteria to evaluate your pupils' progress:
- The pupils understand what a condition is.
- The pupils are able to use conditions in their program.
- The pupils can discuss digital security in detail and with precision.
Have each pupil choose the brick that they feel best represents their performance.
- Blue: I've used one condition in my program.
- Yellow: I've used two conditions in my program.
- Violet: I've used more than two conditions to create a super cool and safe program!
To incorporate the development of language arts skills:
- Have your pupils explore the meaning of digital security terminology, like:
Note: This will require additional time.
