After an experiment, scientists write a ? which summarizes their experiment and results. 10 LETTERS 4. The ? ? is a process used by scientists to find answers to questions or solve a problem. 16 LETTERS 5. The ? variable is the part of the experiment that is being tested or the part that is changed by the person doing the experiment. 11 LETTERS 6. The ? is an educated guess. 10 LETTERS 7. Scientists use their data to make charts and ? to communicate the results of an experiment. 6 LETTERS 8. After the scientist makes a hypothesis, they perform an ? to collect data. 10 LETTERS 9. The first step of the scientific method is to define or identify the ?. 7 LETTERS 10. Sometimes scientists make a mistake, or ?, and need to do an experiment again. 5 LETTERS. 11. The ? variable is the part of the experiment that is affected by the independent variable. 9 LETTERS 12. After the experiment, scientists organize and ? the data. 7 LETTERS 13. The information collected during an experiment is called ?. 4 LETTERS 14. Scientists make ? to help them make a hypothesis or collect data during an experiment. 12 LETTERS If you know the answer to ANY, ANY of these questions, even the smallest of help would be greatly appreciated, but please try to answer as many of these questions as possible! Thanks to all that help in advance! Now I actually only need answers for numbers 2. , 4. , and 14. I just got all the other ones! Thanks so much for that helpful answer Jessica! When yahoo answers lets me I'll choose you as best answer! Thanks soo much! Oh & Jessica I copied all of those notes you gave to me, pasted them into Microsoft Word, printed it out, and now I can use that sheet as a study guide! It's going to be soooo helpful! Thank you!

Answers:1. Control 2. Procedure 3. Conclusion 4. Scientific Method 5. Independent 6. Hypothesis 7. Graphs (assuming) 8. Experiment 9. Problem 10. Model 11. Dependent 12. Collect 13. Data 14. Observations I'm sure you could have found all the answers on a worksheet you've done or in your textbook. I'm going to write down some notes I want you to copy so you have this information so science will make more sense to you (if you're not getting it.) IT WILL BE EXTREMELY HELPFUL FOR FUTURE REFERENCE!!! Define Problem - An approach to problem solving, can be used by anyone from observation or research (ALWAYS a question.) Ex: How much fertilizer makes bean grow the tallest? Form Hypothesis - Educated guess, if... then... because, testable - can collect data (#'s, observations, inference) Ex: IF I test 0, 1 tsp, 2 tsp and 3 tsp of fertilizer on beans, THEN beans will grow tallest with 2 tsp. BECAUSE... Experiment - organized way to test a hypothesis Control: standard for comparison Ex: 0 tsp of fertilizer Constant: stays the same Ex: amount of heat, light, soil Dependent variable: data/results you collect Ex: height of plants (# of flowers, etc) Independent variable: what is tested/what investigator changes Ex: amount of fertilizer (Easy way to remember dependent and independent so you don't get mixed up is D = data.. for dependent and I = investigator for independent) Field Study - Replaces exp. in situtations where many observations are used to collect data Ex: animal behavior, dinosaurs Conclusion - Accept or reject your hypothesis Model (Physics) = an idea or math expression that is similar to what scientists are trying to explain Ex: atom model: solar system Theory = well supported, well tested explanation, which unifies a broad range of observations Ex: dinosaurs extinct from a meteor Law - Explains an action or expected outcome Ex: gravity, math, physic laws Repeat (more hypothesis??) - Publish results, allow others to check your results (LOTS OF DATA NO EXCEPTIONS!) By suggestion improvements or changes, others can learn from your results. I really hope you copy this down it will be so useful to you. Hope this was helpful & good luck!!! :)
