Yara is a girl. She is eight.
Her brother is Omar. He is ten.
They are in the kitchen today.
Mother has a bag of fruit.
There are four round yellow lemons.
Yara looks at the lemons.
Omar looks at the lemons too.
What can we make? asks Yara.
We can make a battery, says Omar.
A battery from lemons? asks Yara.
Yes! It is a lemon battery.
Omar has a science book.
We can read it together, says Yara.
Science is fun for Omar and Yara.
Let us start now, says Yara.
