Our Eco Energy group had another go at circuits; with and without batteries. They had to make a complete circuit in order for the light, buzzer or motor to go. Meg brought along her solar panel and battery that her family uses when camping.
We learnt about living sustainably from the photos Peter (Mrs Olorenshaw's brother) from Nelson, sent to us of his house. We will skype him next week to ask him our questions.
This house had black painted walls with glazing to retain the heat from the sun.
It had large windows allowing the sun to shine on the concrete tiles for a good amount of the day, as it was north facing.
The insulation under the floor helped the heat rise and warm the room. Check out our Eco Energy page for more, including the electric car and windmill!
