Part of the Scientific Process of Inquiry

 Before conducting an investigation, it is important to learn how to organize the data you have collected.  After you have organized the data, you need to make sense of what you have observed.  Data tables and charts are usually the way scientists organize their data.

Gary is not the smartest snail in Bikini Bottom and he believes he can improve his brain power by eating Super Snail Snacks. In order to test his hypothesis, he recruits SpongeBob and several snail friends to help him. The snails ate one snack with the same meal every day for 3 weeks. SpongeBob created a test and gave it to the snails before they started eating the snacks as well as after 3 weeks.

1. Title your lab Collecting Data (on Page 20) 2. Write today’s date and enter into TOC pages 20 & 21. 3. Write: PROBLEM: How high does a ball bounce when dropped from different heights? 4. Write HYPOTHESIS: If I drop a ball from different heights, then the ball will bounce (higher/lower/the same) each time because _______

1. Create a Data Collection Chart 2. Drop a ball onto a table from each of the heights in the chart. Record your data 3. Repeat 3 times for each height and record the data. 4. Find the average for each height and record the data 5. Create a graph. 6. Answer the questions.

Height ball was dropped (cm) Height ball bounced (cm) 1 st attempt Height ball bounced (cm) 2 nd attempt Height ball bounced (cm) 3 rd attempt Average (cm) 10 20 30 40 50 60 70 80 90 100
