Number of paper clips 3. CLAIM: The factors that affect the strength of an electromagnet are. 4. Evidence supporting your claim 5. Reasoning that explains why and how your evidence supports your claim.

4. INVESTIGATING MAGNETIC FIELDS DAY 2 Today: 1. Return Rocket Labs and discuss scores. 2. Complete your initial investigation of electromagnetic forces from yesterday. 3. Choose a factor to study 4. Go to google classroom and complete the latest assignment: Electromagnetic Forces Inquiry Section 1 Rough Draft

5. POSSIBLE FACTORS TO TEST Number of turns/wraps of the wire Wire thickness Number of nails Type of nail Size of nail Type of battery Wire length Number of batteries Length of wire ends Type of paper clips Amount of space left on the nail Amount of tape (number of layers) Amount of surface contact between the wire ends and the battery

6. NEXT STEPS: SECTION 1- FORMING A QUESTION/HYPOTHESIS WITH BACKGROUND SUPPORT Which factors cause a change in the strength of the magnetic field produced by an electromagnet? Question: How does ____________ affect the strength of the magnetic field around an electromagnet as measured by the number of paper clips picked up by the electromagnet? OR: What is the effect of _________________ on the strength of the magnetic field around an electromagnet as measured by the number of paper clips picked up by the electromagnet? Hypothesis: Background Support:

11. NEXT STEPS: SECTION 3- COLLECTING AND PRESENTING DATA Organized data table Appropriate type of graph for your data Graph includes correct title, labels and units of measure Graph is constructed correctly and shows craftsmanship Observations

12. NEXT STEPS: SECTION 4- ANALYZING AND INTERPRETING RESULTS Restate the question and whether it was supported by the data. Summarize the data using specific examples, averages, and general trends. Explain your data using scientific principles. Discuss sources of error and limitations Describe how you would eliminate the sources of error or limitations Suggests questions for further study – should be related to what you learned in this inquiry.
