Finding the solution to a question via the use of multiple research techniques is the process of conducting a method investigation. The study's design or methodology flaws or other shortcomings are those that affected or influenced how the results of the research were interpreted.]]> 2023-02-16 15:07:55 UTC https://padlet.com/haugha5207/1fpgu7rcvgjul59g/wish/2485110411 haugha5207 https://padlet.com/haugha5207/1fpgu7rcvgjul59g/wish/2485144485 2. The Six Steps to the Scientific Method:

1. Ask a Question: To begin with the scientific method, there needs to be a question about an observation.
2. Do Background Research: Before starting anything else, it is always best to do needed background research.
3. Create a Hypothesis: Using the information that you've gathered from the observation and background information, it is now time to create an educated guess about how things will work.
4. Test Hypothesis With an Experiment: This is when it's time to experiment to see if your predictions were correct.
5. Analyze the Data and Make a Conclusion: With the results from the experiment, you should now analyze results and create an analysis based off of what you learned.
6. Communicate the Results: The last step to the scientific process is to share your findings with others in a finalized lab report or display.]]> 2023-02-16 15:30:29 UTC https://padlet.com/haugha5207/1fpgu7rcvgjul59g/wish/2485144485 haugha5207 https://padlet.com/haugha5207/1fpgu7rcvgjul59g/wish/2485150436 3. In an Experiment there are typically two types of variables. Independent variables are expected to influence the dependent variables.

The hypothesis must be clear and make no assumptions about the reader. The theory must also be tested and observable, with results.]]> 2023-02-23 04:08:59 UTC https://padlet.com/haugha5207/1fpgu7rcvgjul59g/wish/2492050447 haugha5207 https://padlet.com/haugha5207/1fpgu7rcvgjul59g/wish/2492052760 In a lab, it is most important to always wear eye protection and gloves when experimenting with irritable substances.
