Societal Impacts of Scientific Solutions (Writing Prompts)

Bridges are designed to be strong and flexible so people can safely use them to travel to different locations. Engineers have to consider the different forces acting on a bridge, such as compression and tension. Materials, such as steel, are often used when constructing bridges due to their strength and ductility. Newton’s first and second laws of motion help engineers study the relationship between the forces on a structure.

Lithium batteries are a special kind of battery that can store a lot of energy long term. They are used in many things like cell phones, spacecraft, laptops, and even electric cars. These batteries are really good because they can hold a lot of energy and last a long time, however, lithium is a rare metal that is difficult to mine. Mining lithium is difficult because it is costly and also affects natural habitats.

Wind energy is a renewable source of energy. Wind turbines use the wind's power (mechanical energy) to make electricity (electrical energy). When the wind blows, it makes the blades of the turbine spin which then turns a generator and makes electricity. Wind turbines can be built in many different locations, from land to the ocean, and from remote wilderness to cities. Wind farms can be as large as hundreds of square miles.

During summer, your classroom becomes very hot, making it uncomfortable for students to study. The school wants to find a way to keep the classroom cooler without using air conditioning. They have decided to use window shades to block out some of the sun's energy. Installing window shades on all 4 windows will cost $135. It is estimated that this will reduce the classroom temperature by 5°F, making it more comfortable for students and improving the learning environment.

Today, the majority of the world's population lives in cities. Green roofs are roofs on buildings that have plants and soil on them instead of traditional shingles. Because of the plants and soil, green roofs absorb rainwater and can prevent flooding. Green roofs help capture the sun’s energy from the sun in urban areas with a lack of plants, trees, and grasses. As the plants grow, green roofs attract other organisms such as birds and insects, promoting urban biodiversity.
