ACTIVITY 2 Materials to be prepared: Medicine dropper, coins (10, 5, 1, peso; 25-centavos) Using a medicine dropper and water, a student determines the number of water drops that different sizes of coins can hold. He gathers the data and records them in the table below NO. OF WATER DROPS No. of Trials 1 2 3 Average 10-peso 45 47 48 47 5-peso 53 52 54 53 1- peso 34 30 32 32 QUESTIONS FOR ANALYSIS 2. By looking at the data, which coin holds the greatest number of water drops? a. a 10-peso coin b. a 5-peso coin c. a 1-peso coin d. a 25 centavo coin 1. What is the problem of the student in this experiment? a. size of the coins b. total amount of coins c. type of medicine dropper d. amount of water drops that different sizes of coin can hold 25-centavos 15 17 17 16 3. Which factor do you think has something to do with the differences in the number of water drops can hold? 6. Which of the following can you identify as the responding variable? a. number of water drops b. size of the coin d. kind of medicine dropper c. diameter of the dropper 7. Where should you base your conclusion or generalization? a. gathered data c. direct observations a. distance of medicine dropper from the coin b. sizes of the coins c. diameter of the dropper d. all of the above 4. If you want to verify whether the size of the coins affects the number of water drops that a coin can hold, which of the following hypothesis will you test? a. The farther the distance of the dropper, the more water drops the coin can hold. b. The bigger the diameter of the dropper, the more water drops the coin can hold c. The bigger the size of the coin, the more water drops it can hold. d. The bigger the water drops, the more each coin can hold. 5. Proving the hypothesis "the bigger the size of the coin, the more water drops it can hold", which of the following variables will remain unchanged? a. amount of pressure on the rubber of the medicine dropper b. distance of the dropper from the coin c. size of the medicine dropper used d. size of the coins a coin b. results of the series of experiment performed d. all of the above​
