Activity 01
Sorting Station: E-Waste Sort
Prepare bins labeled landfill, recycle, repair with pictures of devices and parts. Small groups sort toy tech items or images, then justify choices to the class. Follow with a shared chart of class decisions.
Predict where old iPads and computers go when they break.
Facilitation TipDuring the Sorting Station, label bins clearly with pictures so students can match broken parts to the correct recycling path without confusion.
What to look forGive students a picture of an old iPad. Ask them to draw or write two things that could happen to it and one way they can use their current iPad responsibly.

Activity 02
Energy Patrol: Device Check
Pairs tour the classroom noting computers with screens on, plugged-in chargers, or unused peripherals. Record tallies on a group chart. Discuss and vote on two quick fixes to try next week.
Explain how we can save energy when using our classroom computers.
Facilitation TipFor the Energy Patrol, assign small groups to one area of the classroom so they can observe and record devices systematically.
What to look forHold up pictures of different electronic items (e.g., a working laptop, a broken TV, a phone charger). Ask students to give a thumbs up if it should be recycled, a thumbs down if it can still be used, and a wave if it needs to be turned off to save energy.

Activity 03
Role-Play: Tech Lifecycle
Divide class into stations: use, break, collect, recycle. Students hold props like toy iPads and rotate while narrating steps. End with whole-class recap of key impacts.
Justify why it is important to recycle electronic parts.
Facilitation TipIn the Role-Play, provide simple props like a toy robot or cardboard box to represent devices at each lifecycle stage for easy visualization.
What to look forAsk students: 'Imagine you have an old toy robot that doesn't work anymore. What are two reasons why it is important to think about where it goes?' Listen for responses related to pollution, saving space, and making new things from old parts.

Activity 04
Poster Pair: Save Energy Rules
Pairs draw and label three rules for computer use, like turn off when done. Share posters in a gallery walk. Vote on the class top rule to display.
Predict where old iPads and computers go when they break.
Facilitation TipFor the Poster Pair, give students large paper and markers to collaborate on clear, eye-catching rules they can explain to the class.
What to look forGive students a picture of an old iPad. Ask them to draw or write two things that could happen to it and one way they can use their current iPad responsibly.

Generate Complete Lesson→A few notes on teaching this unit
Teach this topic through multisensory experiences. Students need to hold broken parts, turn devices on and off, and act out the lifecycle to understand cause and effect. Avoid long explanations; instead, let students explore and then guide their observations with targeted questions. Research shows that young learners build understanding through movement and discussion, so keep activities hands-on and conversation-rich.
Successful learning shows when students can explain where old tech goes, identify responsible habits, and sort items based on energy use or recyclability. They should also discuss why these choices matter for the planet.
Watch Out for These Misconceptions
During the Role-Play: Tech Lifecycle, watch for students who think old devices just disappear or go straight to the rubbish bin.
Use the role-play props to act out the journey step-by-step, from donation to recycling center, so students see the clear sequence of steps and where devices actually go.
During the Energy Patrol: Device Check, watch for students who believe switching off screens saves no energy because computers need power anyway.
Have students use the classroom devices to test standby power versus off mode by observing a simple energy monitor or feeling the warmth of a device left on overnight.
During the Sorting Station: E-Waste Sort, watch for students who think recycling electronics does nothing since new devices are always made.
Use the sorting trays to separate raw ore props from recycled metal parts, then ask students to compare the two and explain how recycling reduces the need for new mining.
