Mr. Sam Stirk's Grade 5 Science class is learning about Natural Selection. He passed out sheets of paper to the students and asked each one to make a paper airplane. The kids got into groups and built what they thought was the best one. When they were done, they took turns flying their planes. If their plane didn't fly or fly far, they had to go back and change their design. Mr. Stirk explained that in nature, organisms adapt to their environment to survive.
