23 Ellen noticed that she often sneezes when she visits her friend Robert, who has a cat and a parrot. Ellen wonders if she may have allergies to Robert’s pets and decides to conduct a scientific investigation. What should Ellen do next? Ellen should tell Robert she cannot visit him until he gives away his pets. Ellen should visit Sue who has a horse, a dog, a goldfish, and a hamster. Ellen should call her doctor and insist that she needs shots for allergies. Ellen should visit a friend who has only cats and one who has only parrots. D

27 Daily Double

28 The amount of gravitational attraction between the Earth and an object depends on the objects distance from the Earth and the object’s – shape mass state of matter size B

29 Scientists have been able to find no atmosphere around this planet because it has little gravity and is closest to the sun. The planet described is – Mercury Earth Venus Saturn A
