Introduction

PLTW Activity 1.1.1, titled “Introduction to the Design Process,” is an introductory activity that sets the stage for the Project Lead The Way (PLTW) Engineering Design and Development curriculum. This activity introduces students to the engineering design process, a systematic and iterative approach used to solve engineering problems.

The purpose of this activity is to provide students with a foundational understanding of the engineering design process and its key elements. Through hands-on activities and discussions, students will learn about the different phases of the design process, including problem definition, research, brainstorming, prototyping, testing, and evaluation.

Activity Procedures: Pltw Activity 1.1 1 Answer Key

The activity involves several steps to guide you through the exploration of the engineering design process.

You will be provided with the necessary materials and equipment, including:

• Building materials (e.g., cardboard, straws, tape)
• Design tools (e.g., rulers, protractors, graph paper)
• Testing equipment (e.g., weights, force gauges)

Design Phase

In this phase, you will:

1. Identify the problem or need.
2. Research and gather information.
3. Develop and sketch multiple design ideas.
4. Select the best design based on criteria and constraints.

Build Phase

Once the design is finalized, you will:

1. Gather the necessary materials.
2. Follow the design plans to construct the prototype.
3. Make adjustments or modifications as needed.

Test and Evaluate Phase, Pltw activity 1.1 1 answer key

In this phase, you will:

1. Develop a testing plan to evaluate the prototype’s performance.
2. Conduct experiments and collect data.
3. Analyze the data and make observations.
4. Identify areas for improvement.

Improve and Redesign Phase

Based on the test results, you will:

1. Make necessary modifications to the design.
2. Rebuild and retest the prototype.
3. Repeat the testing and evaluation process until the desired performance is achieved.

Data Collection and Analysis

Now that you have a research question, it’s time to gather data to answer it. Data collection is the process of gathering and measuring information on variables of interest, in an established systematic fashion that enables one to answer stated research questions, test hypotheses, and evaluate outcomes.

The data you collect should be relevant to your research question and should be collected in a way that minimizes bias. Once you have collected your data, you need to analyze it to draw conclusions. Data analysis is the process of inspecting, cleaning, transforming, and modeling data with the goal of highlighting useful information, suggesting conclusions, and supporting decision-making.

Organizing and Analyzing Data

There are many different ways to organize and analyze data. The best method will depend on the type of data you have and the research question you are trying to answer. Some common methods of data analysis include:

• Descriptive statistics: These statistics describe the basic features of your data, such as the mean, median, and mode.
• Inferential statistics: These statistics allow you to make inferences about a population based on a sample.
• Data visualization: This involves creating graphs and charts to help you visualize your data and identify patterns.

Once you have analyzed your data, you need to draw conclusions. Your conclusions should be based on the evidence that you have collected and should be clearly stated.

Activity Modifications

To accommodate diverse learning styles, consider the following modifications:

Differentiation by Grade Level

• For lower grade levels, simplify the instructions and provide more hands-on support.
• For higher grade levels, introduce more complex concepts and challenge students with open-ended questions.

Differentiation by Learning Style

• For visual learners, provide diagrams and graphic organizers.
• For auditory learners, use verbal explanations and discussions.
• For kinesthetic learners, incorporate hands-on activities and experiments.
• For logical learners, emphasize the logical connections between concepts.

Extensions

This activity can be extended beyond the classroom to reinforce learning and connect it to real-world applications.
