Bernard Kettlewell was a British scientist who studied the Peppered Moth. For twenty years between 1952 and 1972, he observed the moths in the field. Over the two decades, he collected data that he used to conclude that the change in the moth’s color from white to black and back to white was due to the change in the color of the trees the moths lived on. If Kettlewell did not follow the scientific method while observing the moths, are his findings still valid?

• Yes, because he made observations and collected evidence.

• Yes, because he was a scientist and scientist are always right.

• No, if he did not follow the scientific method then his findings are invalid.

• No, because he did his work outside of a laboratory.

In 1941, Swiss engineer George de Mestral went for a hike in the Alps with his dog. Upon returning home, he looked at the small Burdock burrs that stuck to his clothes and noticed that the little seeds were covered in small hooks, which is how they became attached to fabric and fur. He had not set out to create a fastening system, but after noting how firmly those little burrs attached to the fabric, he decided to create the material that we now know by the brand name Velcro. Which answer below best describes the discovery of Velcro?

• The discovery is not valid because he was not investigating Velcro.

• The discovery is valid because the scientist made an observation and collected evidence.

• The discovery is not valid because the scientists did not use all of the steps of the scientific method.

• The discovery is valid because an engineer did it.
