In Week 3, we learn green building science by creating a green dollhouse or fort using our printable template and simple passive solar design calculations.

Do some fun sun math to design the coolest house ever.

Apply real green building design skills to create a miniature eco home.

Use half a hula hoop with a small spotlight attached to create a “mock sun” that casts shadows over the toy house.

Use a sun path chart to see the angle of the sun at different times of day, then color in the shadows it would cast on the house.

Print the eco-house template on cardstock. Cut and fold it into a 3D passive solar house, then decorate it with green home features.

The activities are designed to help families take practical decarbonization and energy-saving actions at home.
Each week includes a “Home Action Card” with simple actions, tips, and guidance for parents.
Think of it as “climate homework for parents.”
