Now he wants to see shat happens when the amount of water is reduced, as shown in the information below.  Plant 1 - 1/2 cup two times per week; Plant 2 - ½ cup ounce per week; Plant 3 - ½ cup once every two weeks; Plant 4 - no water. a) Plant 1 b) Plant 2 c) Plant 3 d) Plant 4 10) Observations are made using the five senses. We can use observations to draw conclusions. Which of the following is a conclusion? a) "The object is flat." b) "The flower smells like mint." c) "Crickets chirp to attract mates." d) "The food tastes salty." 11) Four students threw darts at the center of a dartboard. which target shows the most accurate results? a) b) c) d) 12) Samara observes and sketches the phases of the moon during a five-week period. Her drawings are shown here. a) It involves modelling. b) it involves experimentation. c) It involves repeated observations. d) It involves both experimentation and repeated observations. 13) Sometimes the results of an investigation are not what were expected. When this happens, what should a scientist do? a) Change the results b) Defend the results as correct c) Plan another investigation to test the results of the first one. d) Ignore the first set of results and plan a different investigation. 14) Why do scientists repeat their experiments? a) To avoid making observations. b) To throw out the information they collected earlier. c) To develop a new procedure that they can use later. d) To make sure that the information they collect is reliable. 15) Maria counts the number of people who attend several basketball games. She displays her data using a graph. Game 1- 200; Game 2 - 350; Game 3 - 100; Game 4 - 250. How many more people did Maria observe at Game 2 than at Game 1? a) 100 b) 150 c) 200 d) 550 16) Jen wants to find out which of four surfaces produces the least friction when a ball rolls over it. She designs an experiments in which the same type of object rolls over each material under the same conditions. She repeats the experiment three times for each material, averaging how far the object travels before stopping during the three trials. Which would be the best way for Jen to record her observations and data? a) in a table b) as a line graph c) as a circle graph d) in a Venn diagram 17) Asa watches his mom rub soap on her finger to help her get a ring unstuck. He thinks the soap must reduce friction. He designs an investigation to test his idea. He pulls a weight across a board and records the force with a spring scale. He then puts soap on the board and pulls the weight again at the same speed. Which of the following variables is Asa measuring? a) The speed with which the weight is pulled. b) The amount of weight being pulled c) The force needed to pull the weight d) The type of surface the weight is being pulled across. 18) A procedure carried out to carefully observe, study, or test something in order to learn more about it; is an a) Science b) Investigation c) Evidence  d) Opinion 19) The study of the natural world and involves making observations and performing investigations. a) Investigation b) Science  c) Evidence d) Opinion 20) Information collected during a scientific investigation is a(an) a) Opinion b) Investigation c) Evidence d) Science
