Scientific Method Practice Write the following on your whiteboard: Manipulated variable (can abbreviate mv)= Responding variable (Can abbreviate rv)= Control variables (can abbreviate cv’s)= Experimental Group= Control Group= Validity Measures=

Scientific Method Practice Mrs. Crain wanted to see how different types of music affected students' pulse rates. She played different types of music: heavy metal, rap, R&B, alternative, pop, country, and classical music.

Scientific Method Practice Mary investigated the effect of different concentrations of Miracle Grow on the growth of tomato plants. She grew four groups of tomato plants (10 plants/group) for 30 days. She then applied Miracle Grow as follows: Group A, 0% Miracle Grow; Group B, 10% Miracle Grow; Group C, 20% Miracle Grow; and Group D, 30% Miracle Grow. The plants received the same amount of sunlight and water each day. At the end of 30 days, Mary recorded the height of the plants (in centimeters) and the color of the leaves (green, yellow-green, yellow, or brown.)

Scientific Method Practice Students of different grades were given jigsaw puzzles to solve. The amount of time to solve each was recorded.

Scientific Method Practice Josh wanted to test what kind of paper is best to make paper airplanes out of. He made identical paper airplanes out of: construction paper, notebook paper, wrapping paper and card stock. He measured how far in cm each airplane flew.
