Build a catapult to attack enemy territory 

 collaborative exploration of various design concepts within our team contributed to a better understanding of creative problem-solving in engineering design. We were able to create several designs, and then we decided on the best idea which would successfully launch paper balls on the enemy territory

Choosing the right design for a catapult made from ice cream sticks, a spoon, and rubber bands means ensuring it works and is safe and fair. We must consider using these materials carefully so we don’t waste them or accidentally hurt someone. It's about being creative while also respecting others' ideas and safety.

Thinking about different designs for a catapult made from ice cream sticks, a spoon, and a rubber band helped me solve tricky problems better. I learned to think outside the box and not stick to the same solution by trying out various ideas. This improved my catapult and taught me to be more flexible and creative in solving challenges.

Steps of making a catapult.

The role-play activity made us work together as a team, which was helpful. By sharing our ideas and knowledge, we were able to figure out exactly what we needed to do, how we could do it, and what challenges we might face. We were able to identify objectives, functions, and constraints.

The role-play activity opened my eyes to how engineering brings different fields together to solve problems. This experience highlighted the importance of working together across specialties.

Considering constraints, like how much money we have, how much time we can spend, and what materials we can use, making our solution better and more doable. Knowing these limits from the beginning made us think more challenging and more creatively about how to solve the problem. This way, we ensured our solution was a good idea and something we could make.

iv. Pugh Chart

The criteria we chose to evaluate and select the best concept in the punge chart were cost , ease of use, durability, maintainance, portability, accuracy, autonomy these all criteria helped to chooose the best design among all, taking in consideration of all the criteria we were able to come up with the best solution.

The Pugh chart is a tool in engineering and design projects evaluating various design options against crucial criteria. It works by listing all the potential designs and comparing them against these criteria to see which ones meet the project's needs the best. This helps identify the most valuable design features. It helps teams select the most important criteria and how different designs fulfill them. The Pugh chart plays a critical role in the success of the design.

Our team's collective thinking helped us carefully evaluate all our design options. By discussing and analyzing each concept's pros and cons, we chose the best one for our project. This teamwork and thoughtful decision-making were important to our project's success, ensuring that we chose a design that met our goals and worked well.

Material selection based on sustainability is a critical approach in industries ranging from construction to fashion, focusing on reducing environmental impact and promoting ecological balance. Sustainable materials are typically renewable, require less energy for production, and generate minimal waste, making them more environmentally friendly. Examples include bamboo, which grows quickly and absorbs CO2, recycled metals that reduce the need for virgin mining, and organic cotton, which avoids harmful pesticides. The selection process involves assessing the lifecycle of materials, considering factors like energy consumption, water usage, and recyclability. By prioritizing sustainable materials, businesses and consumers can contribute to conservation efforts, reduce pollution, and support a healthier planet for future generations.
