Obtaining, evaluating and communicating information Being able to read, interpret, and produce scientific and technical text are fundamental practices in science. By some estimates, reading and writing scientific texts consumes more than half of a scientist's workday. Being a critical consumer of information requires the ability to comprehend scientific reports, rec- ognize salient ideas, identify sources of error and methodological flaws, distinguish observation from infer- ence, arguments from evidence, and claims from evidence. Communicating scientific evidence and ideas is accomplished through many modes: tables, diagrams, graphs, models, equations, and narrative text. PART I. OBSERVING A PHENOMENON Have you ever noticed that the color of an m&m comes off on your hand? Predict Write a prediction about what you think will happen when you place one m&m in water. PROCEDURE Fill one half of a petri dish half full of water. Place one m&m into the center of the dish of water. Record results. How did your prediction match the results? Predict Write a prediction about what you think will happen when you place two m&ms in water. PROCEDURE Fill one half of a petri dish half full of water. Place two m&ms into the center of the dish of water. They should be close to one another but not touching Record results. SCIENTIFIC PROCESSES: INVESTIGATING PROPERTIES OF M&Ms-EXERCISE 1 1 5 How did your prediction match the results? ᎠᎴ PART II. RUNNING AN AUTHENTIC EXPERIMENT When scientists observe a phenomenon that intrigues them, they normally want to investigate. After observing the candy in the water, design a series of experiments that allow you to investigate the phe- nomenon. This is your research plan. Be sure to think about variables and controls. Start with one testable question. Carry out one experiment at a time, comparing your results to your hypothesis before moving on to a new test. The results of one experiment should help you write the next consecutive question. You should carry out a minimum of five different experiments. In a research lab, there are constraints on doing experiments because of time and funding. Your lab group will be given funding to spend at your discretion on supplies. If you run out of funding, but want to carry out additional experiments, you must write a short justification and budget request and submit it to the instructor. You may be given additional grant money to buy the supplies. You will need to write a budget report that explains where your research funds were spent. REN EXPERIMENTS: 1.

What additional question would you like to investigate about this phenomenon? SCIENTIFIC PROCESSES: INVESTIGATING PROPERTIES OF M&M-EXERCISE 1 17 3. Refer back to the list of process skills used in scientific investigation. List three skills you used in this investigation and explain how you used each one. 4. Did you feel that having a limited budget for supplies changed the way you approached the exper- imental process? Explain. WHAT YOU NEED TO TURN IN For this lab, you need to turn in the budget report for your group, your list of questions, hypoth- eses and results for each experiment, and the answers to the analysis questions. Be sure to write your name at the top of each page.
