1. The lighthouse lens takes about eight seconds to go around. About how many times does it go around in one minute? (HINT: 60 seconds = one minute) 2. When Sam went into the light/shadow room and held up both hands, he saw that each of his fingers made a red, a green, and a blue shadow. How many different fingers did he see on the wall? If two of his friends did the same thing, how many fingers would be reflected. Write your answer in a sentence. 3. Jamar stood in front of the mirror that shrinks him to half his size. He is 42 inches tall in real life. How tall is he in the mirror? Is this bigger or smaller than two feet? 4. Lucian gave 10 people in Ms. Lightenaire's class a light seal. How many points did they get altogether? 5. Atlanta has three bubble machines. Six of Ms. Lightenaire's students got a chance. How many turns is that? 6. Let's say it takes five pounds of rock to sink a boat in the float
and sink display. Matt, Anna, and Nick tried to see who could keep the
boat afloat after putting three rocks on it. Which of these were able to
do it?
- Matt: 2 pound rock, 14 ounce rock, 35 ounce rock
- Anna: 28 ounce rock, 24 ounce rock, 1 pound 4 ounce rock
- Nick: 35 ounce rock, 19 ounce rock, 27 ounce rock
7. Tommy and Timmy decided to make the waterwheel turn. Tommy was the counter. Timmy pulled the rope 15 times and the wheel went around once. He pulled it 30 times and it went around two times. If the rope was pulled 60 times, predict how many times the waterwheel will turn. 8. Candy made her fountain go up in 10 spins. Sandy only needed four spins. How many fewer spins did Sandy need? Andy did it twice as fast as Candy. How many spins did Andy do? 9. Remember when you were an Architect and Apprentice in the Earth section and had to give your friend directions to build with blocks? Look at these letters and write directions for someone so it could be put on paper.
10. On the bubble maker, the faster you pump, the bigger the bubbles.
