Lesson Plan: LEGO® Education Spike™ Prime - SoapMax

Designed for Ages 9-14

Curriculum Connection:

Computational Thinking for Digital Technologies
Progress Outcome One
Progress Outcome Two
Progress Outcome Three

Designing and Developing Digital Outcomes
Progress Outcome One
Progress Outcome Two 


Aim:

Students will work in pairs or individually to create an automatic hand soap or sanitizer dispenser, using LEGO® Education SpikeTM Prime.

They will need to go through the design process and practice each part of their code to ensure they are dispensing one pump of soap/sanitizer each time someone places their hands under the motion sensor.



Materials:

Lesson Outline:


Step 1:

Before you start, "warm up" by going through the mini lessons designed by LEGO® Education. Have students complete at least one task to get their creative brains switched on.


Step 2:

Begin the lesson by discussing why we are investigating this form of technology. What is happening at present that makes hand sanitization so important?


Step 3:

As a class, start to sketch out what they consider to be a good design for an automatic dispenser. 

Where have they seen this type of technology before? Airports? Bathrooms? Shop entrances? Etc.

Step 4:

Discuss whether any of their sketches have anything in common. Discuss levers and pulleys and the idea around different types of sensors.

Ensure you connect back to the real world as much as possible. For example: How much of our world is now automated? Compare this to the last decade, and the decade before that. How have these advances in technology changed the way people live? Why are we still fighting a virus even with this level of automation?


Step 5:

After the sketches have been analysed, show them the LEGO® Education Spike Prime Core kit.


Step 6:

Give the students time to explore, test and create with the kit (they do not need to complete the design now, this step is just to get a feel for the materials).


Step 7:

Give students a copy of the STEAM design process template. Ask them to complete the first 4 boxes.


Step 8:

Give them time  to do some research. They may find some ideas on YouTube or the LEGO® Education website.


Step 9:

Ask the students to adjust their initial design according to what they learned in their research. Then, it's time to build! Remind them that they will not only need to build the machine, but code it too.


Step 10:

Remind students to test as they go (this is where the empty pump bottle will come in handy). After each piece of code, they must test that it's doing what they need it to.

Here is an example of what their coding may end up looking like:

Soapbot Coding Example
Step 11:

REVISE and RE-CREATE. Ensure the students document their process as they work through their issues. Use boxes 5 and 6 on the template for this.


Step 12:

Lastly, check out each other's creations!
