Tom and his sister are at home.
They want to cook cheese.
The sun is hot today.
Tom gets a big box.
The box is from the kitchen.
They put black paper inside the box.
The black paper makes the box warm.
Tom and his sister smile.
They want to make food.
The sun helps them today.
They look at the bright sun.
They think about heat from the sun.
They see a clear sky.
They feel the warm air.
They smile at the sun.
They plan a new project.
