Students were studying how temperature affects water movement. The students added drops of food coloring to different temperatures of water.They measured the rates at which the food coloring spread throughout the water. Which tools would best help the students complete their investigation?
A. beaker, thermometer, stopwatch
B. meter stick, thermometer, beaker
C. spring scale, thermometer, stopwatch
D. graduated cylinder, thermometer, balance
Well, saying that they were measuring temperature....they will need a thermometer and a beaker to measure the amount of liquid, and lastly a stopwatch if they wanted to fast(the rate) that it could move.
The best tools to help the students complete their investigation would be:
A. beaker, thermometer, stopwatch.
Explanation:
1. Beaker: The students need a container to hold the water and allow them to observe the movement of the food coloring. A beaker can fulfill this purpose.
2. Thermometer: The students need to measure the different temperatures of the water in order to understand the effect of temperature on water movement. A thermometer can accurately measure the temperature.
3. Stopwatch: The students need to measure the rates at which the food coloring spreads throughout the water at different temperatures. A stopwatch can help them accurately measure the time taken for the spread.
Therefore, option A, beaker, thermometer, and stopwatch, would be the most appropriate combination of tools for the students to complete their investigation.
