Jane and David have decided to do an experiment testinghow sunlight affects plant growth.The students choose the same type of plants, soil, pots and amount of water they give the plants.They also make sure each plant is put in their designated areafor the same amount of time each day.One plant is placedoutside; one in front of a window that only gets light for 1/2 the day, and one in a closet. The students collect data every day for two weeks.Their results show that the plant outside grew the most and the plant in the closet had the least amount of growth.
What are the constant variables that Jane and David used in their experiment?

a)
type of plant
b)
type of soil

the amount of light
d)
type of plant and soil

Sally and Juan’s science teacher challenged her students to build a paper airplane that would stay airborne for ninety seconds. The students have two days to design and test their planes. The assignment will end with a “fly-off.” First Sally and Juan researched plane designs. Then theybuilt their first plane. Whenever they tested the plane, it would take a nosedive straight into the floor. They changed the design by reshaping the nose of the plane and adding some weight to the tail. The plane flew, but did not get very far.Finally they tried to change the way they threw the plane. After many tries, their plane stayed in the air an average of ninety-two seconds.
According to the Technological Design Process, what should their next step be
According to the Technological Design Process, what should their next step be
a)
designing a product
b)
identifying a problem
c)
evaluating the design
d)
implementing (testing) the design
