Some good hook ideas:
1. We all throw trash away. Potatoes, plates, and phones. But about those phones... Where does it go?
2. What does your phone become after you throw it away? E-waste!
3. We all throw stuff away. But what about or phones, laptops, or speakers? That's called e-waste.
4. What happens to your speakers when you throw them away? They become e-waste.
5. What happens to all your electronics when you throw them away? They become e-waste.
6.Have you ever wondered what e-waste was? Ecological waste? Or maybe Edgy waste? Nope! It's electronic waste.
Hope these are some good hooks. Good luck with your presentation!
