This week, the students finished collecting their data, and analyzed their results. Each group has recorded the amount of liquid, the size of the solid, and the number of feet their bug jumped. Looking at the results, the groups determined the best formal to make their bugs jump. Once they have determined their best formula, the groups plotted their results on a line plot.

The lab was jumping this week, literally!!! The excitement level was beyond 10, and the students were ready to collect the important data they have been preparing for. The students were put into groups of three, and then each group assigned a writer, one person in charge of the liquid, one in charge of the solid, and one in charge of the gas. We discussed that gas is the state of matter that causes the bug to actually jump. Once the jobs were assigned, the students began writing four different formulas they were going to try. Their testing is to determine which formula will cause their bug to jump the furthest. Some classes had a chance to do more testing than others, so we will continue to test next week. So much fun! The anticipation is building! This week, the students have selected, colored, and glued their bugs to the film canisters. They are ready to make them jump! The classes reviewed the states of matter this week, and we discussed what state of matter actually causes their bugs to jump. I modeled the testing process for the students, and we discussed the safety precautions. Next week, the students will begin testing the different formulas. How much solid and liquid will be used to make their bugs jump the furthest?
The first and second graders are starting a new challenge this week. Each student will work in a group to find the best formula of water and alma-seltzer tabs to make their bugs jump the furthest. To understand the science behind the challenge, the students investigated matter. They were given three balloons filled with different kinds of matter. Each group had to describe the matter inside, and identify it. The next step to prepare for the challenge, the students were given time to practice with the tools that they will be using during the investigation. Each team will have syringes, film canister "bugs", water, alma-seltzer tabs, rulers, yard sticks, and data collection tables. |
