Title: * a brief, concise, yet descriptive title
Example: 'Types of Invertebrates Found in Pond Water'
Introduction: (State the problem or question to be answered)
*What question(s) are you trying to answer?
* Not all experiments start with a question, some start with an observation and questions develop from further observations
* Include any preliminary observationsor background information about the subject
* Not all experiments start with a question, some start with an observation and questions develop from further observations
* Include any preliminary observationsor background information about the subject
Example: How many different types of insects are found in pond water? Does the location of the pond change the types of insects that live there? Does water quality affect the number of organisms?
Hypothesis:
* Write a possible solution for theproblem or an explanation for the observation
* Make sure this possible solution is a complete sentence.
*Make sure the statement is testable, you may also include a null hypothesis.
* Make sure this possible solution is a complete sentence.
*Make sure the statement is testable, you may also include a null hypothesis.
Example: Ponds located near populated areas will have less organisms than ponds found in isolated areas.
Materials and Methods:
*Make a listof ALL items used in the lab. Alternatively, materials can be included as part of the procedure.
Example: Pond water, strainers, microscopes, field guides, petri dishes
*Write a paragraph(complete sentences) which explains what you did in the lab as a short summary. Include the dependent and independent variables.
Example: Water was sampled from each pond and examined under the microscope. A field guide was used to identify the types of organisms found and estimations of numbers were recorded.
The manipulated variable is the pond location, the responding variable is the number of organisms.
Results (Data):
* Thissection should include any data tables, observations, or other information collected during the procedure.
* Organize data onto tables and charts.
* Graphs and charts should be labeled appropriately (X and Y axis)
* Do not explain of make inferences at this points.

* Do not explain of make inferences at this points.
Conclusions:
* Accept orreject your hypothesis.
* EXPLAIN why you accepted or rejected your hypothesisusing data from the lab.
* Include a summary of the data - averages, highest,lowest.etc to help the reader understand your results. Try not to copy your data here, you should summarize and reference KEY information.
* List one thing youlearned and describe how it applies to a real-life situation.
*Discuss possibleerrors that could have occurred in the collection of the data (experimental errors) and suggest ways the experiment could be improved.

The engineering design process is a series of steps that engineers follow to come up with a solution to a problem. Many times the solution involves designing a product (like a machine or computer code) that meets certain criteria and/or accomplishes a certain task. This process is different from the Steps of the Scientific Method, which you may be more familiar with. If your project involves making observations and doing experiments, you should probably follow the Scientific Method. If your project involves designing, building, and testing something, you should probably follow the Engineering Design Process. If you still are not sure which process to follow, you should read Comparing the Engineering Design Process and the Scientific Method. This diagram shows the steps of the engineering design process, and the table below describes each step in more detail:
The engineering design process begins by defining a problem and completing background research on the problem. Requirements are specified and a solution is chosen. A prototype of the solution is built and then tested. If the solution built meets the requirements then the results can be shared. If the solution does not meet all the requirements then another solution is thought of and tested. Each iteration should use the data from the previously tried solution to meet all of the initial requirements.
Engineers do not always follow the engineering design process steps in order, one after another. It is very common to design something, test it, find a problem, and then go back to an earlier step to make a modification or change to your design. This way of working is called iteration, and it is likely that your process will do the same!

Steps of the Engineering Design Process
1. Define the Problem
The engineering design process starts when you ask the following questions about problems that you observe: Movavi pdf editor 3 0 100.
- What is the problem or need?
- Who has the problem or need?
- Why is it important to solve?
[Who] need(s) [what] because [why].

2. Do Background Research
Learn from the experiences of others — this can help you find out about existing solutions to similar problems, and avoid mistakes that were made in the past. So, for an engineering design project, do background research in two major areas:
- Users or customers
- Existing solutions
For detailed help with this step, use these resources:
3. Specify Requirements
Design requirements state the important characteristics that your solution must meet to succeed. One of the best ways to identify the design requirements for your solution is to analyze the concrete example of a similar, existing product, noting each of its key features.
For detailed help with this step, use these resources:
4. Brainstorm Solutions
There are always many good possibilities for solving design problems. If you focus on just one before looking at the alternatives, it is almost certain that you are overlooking a better solution. Good designers try to generate as many possible solutions as they can.
For detailed help with this step, use these resources:
5. Choose the Best Solution
Look at whether each possible solution meets your design requirements. Some solutions probably meet more requirements than others. Newsletter expert 2 1. Reject solutions that do not meet the requirements.
For detailed help with this step, use these resources:
6. Develop the Solution
Development involves the refinement and improvement of a solution, and it continues throughout the design process, often even after a product ships to customers.
For detailed help with this step, use these resources:
7. Build a Prototype
A prototype is an operating version of a solution. Often it is made with different materials than the final version, and generally it is not as polished. Prototypes are a key step in the development of a final solution, allowing the designer to test how the solution will work.
For detailed help with this step, use these resources:
8. Test and Redesign
Layout Lab 3 3 3 Rule Adopting A Dog
The design process involves multiple iterations and redesigns of your final solution. You will likely test your solution, find new problems, make changes, and test new solutions before settling on a final design.
For detailed help with this step, use these resources:
9. Communicate Results
To complete your project, communicate your results to others in a final report and/or a display board. Professional engineers always do the same, thoroughly documenting their solutions so that they can be manufactured and supported.
