Learning Target: SWBAT write an
effective scientific question and
hypothesis
The subject of science is based around
asking questions & trying to answer these
questions with experiments. What do you
think makes up a scientific question? Be
specific.

Rancher Muriell believes adding organic feed to her
sheep feed will improve their growth rate (kilos) from the
sheep that receive non-organic (chemical) feed.
She groups her sheep into two groups and gives them
the same amounts of the different feed. All the sheep
receive the same amounts of water and exercise. She
measures the sheep’ growth every five days for seven
weeks.
