2. A) The Scientific Method It all starts with asking a question, forming a hypothesis, gaining information through experimenting, and then coming up with an educated conclusion (answer). The way scientists learn and study the world around them.

4. Ask a Question (Step 1) Starts when you ask a question about something that you observe: How, What, When, Who, Which, Why, or Where? Examples: Why do dogs & cats have fur? Why do the tornadoes form? When does thunder and lightning occur the most? Why do spiders spin webs? How to different buildings stand up to earthquakes?

5. Do Background Research (Step 2) In order to design an appropriate experiment, you need to research the topic including the best techniques and equipment for investigating it. To help you along, identify the key words in your question to research. Researching your experiment beforehand is the difference between guessing and having a hypothesis. Where can you find information? The internet, library (books, magazines, journals, etc…), text book etc.

6. Construct a Hypothesis (Step 3) A hypothesis is an educated guess about how things work based on the scientist’s background research and observations.

7. Test with an Experiment (Step 4) Your experiment proves whether your hypothesis is true or false. You should also repeat your experiments several times to make sure that the first results weren't just an accident.

8. Analyze Data (Step 5) Once your experiment is complete, you collect your measurements and analyze them to see if your hypothesis is true or false. How to analyze your results more proficiently? 1) Make a table 2) Chart your results through a graph to help find a pattern

9. Report Results/Conclusion (Step 6) To complete the scientific method, you must communicate your results to others in a final report. Professional scientists do almost exactly the same thing by publishing their final report in a scientific journal or by presenting their results on a poster at a scientific meeting.

11. C. Problem Activity Elastic Band Experiment Equipment to be used by each group: Rubber Band Yardstick (1m) Ruler (30 cm) OR (next slide) Aim: To determine if the length to which an elastic band is stretched affects the distance the paperclip will travel

12. C. Problem Activity Paper Folding Equipment to be used by each group: 279 cm x 432 cm (11 inch x 17 inch) blank white paper 216 cm x 279 cm (8 ½ inch x 11 inch) blank white paper Aim: To determine if the size of paper affects the maximum number of times it can be folded in half.
