| He put both the bouncy ball and golf ball at the top of the ramp. He released them one at a time and waited until they stopped rolling. He then measured that distance from the end of the ramp. | Perform the experiment |
| Which ball will roll down the ramp further, the bouncy ball or the golf ball? | State the question or the problem |
| Stephen predicted that the golf ball would roll farther than the bouncy ball. | Identify the hypothesis |
| Golf balls roll farther than bouncy balls down a ramp. | Draw a conclusion |
| The golf ball rolled 26 m and the bouncy ball rolled 20 m past the end of the ramp. | Collection of data |
| She recorded that no eggs were broke at 10 cm, 3 white and 4 brown eggs broke at 20 cm, and 8 white and 7 brown broke at 25 cm. | Collection of data |
| She hard-boiled 12 white eggs and 12 brown eggs. She then dropped them from different heights to see which ones broke easiest. | Perform the experiment |
| Belinda thought that brown eggs would be harder than white eggs. | Identify the hypothesis |
| White eggs and brown eggs have shells that are about the same hardness. | Draw a conclusion |
| Which type of chicken egg shell is harder, white or brown? | State the question or problem |
| Johnny planted two potato plants in his garage. He put a green light over one and a regular light over the other. He turned the lights on for ten hours every day. | Perform the experiment |
| After collecting the results, Johnny wrote down that potato plants grow the same in green and regular light. | Draw a conclusion |
| Johnny figured that potato plants would grow better in green light. | Identify the hypothesis |
| She collected the results and wrote down that the wood glue bridge held 8 science books before breaking and the super glue bridge only held 3 books. | Collection of data |
| Susie estimated that super glue would hold three times as much weight as wood glue. | Identify the hypothesis |
| Does super glue really work better than wood glue? | State the question or problem |
| She built identical bridges out of Popsicle sticks. She used wood glue on one and super glue on the other. | Perform the experiment |
| Wood glue works better than super glue in holding Popsicle stick bridges together. | Draw a conclusion |
| Do potato plants grow better in green light or regular light? | State the question or problem |
| Johnny collected data every week. After eight weeks, the potato plants were both 175 centimeters tall. | Collection of data |
