Activity B2 Required Skills Inquiry Lab Student Reference 5, 7 Initiating and Planning Performing and Recording Studying Uniform Motion Analyzing and Interpreting Communication and Teamwork The Question 2 At one end of the masking tape, make a pencil mark What kind of motion do falling dominoes exhibit? designating the starting position, 0.00 cm. From this starting position, make a mark every 50.00 cm on the masking tape, using the metre-stick or measuring tape. The Hypothesis (3 Place the metre-stick or measuring tape parallel to the State a hypothesis concerning the motion of the falling masking tape at the start position so that the 0.00 mark dominoes. Be sure to write an "if/then" statement. aligns with the 0.00 mark on the masking tape. Variables 4 Place the first domino at the 0.00 cm mark on the Identify the type of data you will collect to support your masking tape (Figure B1.11). Place the next domino at hypothesis. State the manipulated, responding, and 4.00 cm, and continue lining up the dominoes every controlled variables in this investigation. 4.00 cm until you have at least 65 dominoes in a line. One member of the group (each group has 6 students) positions him- or herself at the 0.00 cm, 50.00 cm, Materials and Equipment 100.00 cm, 150.00 cm, 200.00 cm, and 250.00 cm 65 dominoes (2.5 cm x 5.0 cm) marks. Each student has a stopwatch except for the student at the 0.00-cm mark. metre-stick or measuring tape 5 stopwatches When the student at the 0.00-cm mark says "Start," he or she pushes over the first domino and the other masking tape students start their stopwatches. 7 Each student stops his or her stopwatch when the toppling dominoes reach his or her mark on the tape. Procedure B Record your results in a table like the one below. 1 Paste 3.00 m of masking tape on a flat table or counter- Do at least three trials of the experiment, and calculate top, making sure that the masking tape is perfectly the average values of the times.
