Introduces building and coding using the Light Block.
Max and Mia’s story can introduce the topic to your students and set the stage for your classroom discussion.
Read the following story aloud or allow your students a few minutes to read it on their own.
Max and Mia visit an aquarium. They see a rare snail.
The snail sends out flashes of green light to communicate.
They want to build a model of the snail.
Max and Mia need your help!
Words you might need to introduce to your students: aquarium, rare, communicate
2. Build the model
Students should follow the building instructions to build the model of the snail.
Please be aware that the building time can vary depending on the students’ prior knowledge of building with LEGO® bricks.
Please ensure that the Smarthub has fresh batteries or that the Smarthub Rechargeable Battery is charged.
3. Connect the model to your device
To make it easier for the students to connect with the right Smarthub, it is recommended that you name the Smarthubs (e.g., WeDo001, WeDo002) prior to the lesson. This can be done in the connection center.
4. Program the model
This program will make the snail show a flash of green light.
- Create the program shown by dragging and dropping the relevant program block(s) onto the screen.
- Press the default color number (1) and change it to green (5).
- Press the yellow Start Block to run the program.
Explain to each other how the snail works.
Once the students have created and run their programs, ask them to think about and explain the program and the function of the snail.
They should be able to answer questions like:
- How does the program work?
- What do the different program blocks do?
5. Help Max and Mia further
(optional, 2-3 minutes)
Use this optional extension task to build on students' prior learning as they investigate additional ways of using the Light Block.
Students can, for example, add several Light Blocks showing the same color one after the other, or change the color of every Light Block they add.
Giving timely feedback can help students to further develop their newly-acquired skills. This can be done in several ways, including:
- Observing each student’s behavior, reaction, and strategies
- Asking questions about their thought processes
You can use the assessment criteria below as guidance:
- The student is unable to create a program or adequately explain how the model works (e.g., the program string and its different program blocks).
- The student is able, with prompting, to create a program or adequately explain how the model works.
- The student is able to create a program and adequately explain how the model works.
- The student is able to create a program and explain the different program blocks and how these influence how the model works.
7. Next Steps
