My green invention





答案


Task 4:(此题答案仅供参考)
My green invention
I would design an "Eco-Water Saver"
to help save water and care for plants.
It collects rainwater in recycled plastic
bottles, uses a solar panel to power a
small pump, and has a soil sensor(传感器) that
automatically(自动地) waters plants when the
soil is dry. This invention is eco-friendly
because it uses recycled materials and
solar energy, reducing waste and
conserving water. With this, I hope to
contribute to a greener world!
