Fifth Grade, Environmental Engineering Science Projects (19 results)

The human population on Earth is now more than 7.5 billion, and growing quickly. With more and more of us living an energy-intensive, modern lifestyle, the environmental stresses from human activity continue to increase. Greenhouse gases leading to global warming and fertilizer runoff resulting in marine "dead zones" are just two examples of large-scale environmental impacts from human activity. See how science, engineering and technology can help us take good care of our environment while still enjoying the comforts of a modern lifestyle.

Science Fair Project Idea
Scientific Method
Do you filter your tap water before drinking? Many commercials claim these filters make your drinking water cleaner and safer. But what, exactly, are these filters doing, and is the water really cleaner afterward? The cleaning power comes from their filtering material, called activated carbon. It exists in various forms: powder, granules, foams, and blocks. Do you think it matters what type of activated carbon is inside the filter? In this project, you will investigate whether larger or smaller… Read more

Soil erosion can cost the world billions of dollars every year by washing pollutants into our streams and rivers and by causing the loss of farmland. What can you do about this problem? Help save the world (and some money!) with nothing more than a few plants! Read more

Can AI understand human language? In the future, AI could aid in emergency interpretive service in the hospital when translators aren't available. But can current AI algorithms understand non-verbal languages like sign language? In this science project, you will test whether AI can learn sign language gestures or phrases to see if it can be used for interpretation. Read more

Engineering Design Process
Water is a valuable resource, and water shortages are a serious problem in many parts of the world. The problem can be made worse by people who waste water; for example, by watering a garden or using sprinklers on their lawn (or a farmer taking care of an entire field) when it has rained recently or the soil is already moist. How can you help conserve water and prevent such waste? One way is to build an electronic soil moisture sensor. This project will show you how to build a circuit that… Read more

Scientific Method
Living in the industrialized world, like the United States, we are fortunate because we don't have to worry about the quality of our drinking water. Your community has the means to clean and provide water to you. But in many parts of the world, people don't have this luxury. Whether it is due to war or poverty, the lack of clean water leads to many health and social problems. In this environmental engineering science project, you will learn about different methods to filter out impurities in… Read more

Have you ever seen news coverage or other pictures of an oil spill in the ocean and wondered how all of that oil could be cleaned up? Oil spills can devastate wildlife by covering them with oil, and they can damage our precious water resources by contaminating them with oil. Part of the problem of dealing with oil spills is that the oil can be challenging to clean up. In this science project, you will test the absorptivity of different materials (called sorbents) to discover which ones are best… Read more

Scientific Method
What do humans need to survive? We need food, water, and warm shelter. We all need a warm place to live, particularly when it's chilly outside. How do many of us warm our houses or apartments? We depend on fossil fuels to supply gas and electricity to our heaters. But burning fossil fuels to create energy is harmful to the environment. What if there was a way to warm our homes without burning fossil fuels and it was free? In this science fair project, you will build a solar air heater and see… Read more

Scientific Method
Landslides are powerful geological events that happen suddenly, causing fear in people who live in areas with unstable hills, slopes, and cliff sides. Landslides damage the surrounding habitat and can destroy homes in their path. But what causes landslides? Can slides happen on any slope, or do slopes have to have certain characteristics, such as a steep angle and a specific material mass? In this geology science project, you will learn about the different types of landslides and the… Read more

The enormous task of cleaning up oil spills in oceans and seas has burdened industry, government, and environmentalists for decades. The cleanup is almost always difficult. It involves great amounts of time, resources, and money to remove the oil from the water, and the cleanup is often only partially successful. Today, however, scientists are coming to the rescue, developing a new technique that combines nanotechnology and magnetism. In this science project, you will test the proposed… Read more

One way to save water is to turn the faucet off while you brush your teeth. But did you know that there are products that can help save water even while the water is on? In this experiment find out how low-flow faucets and aerators work to reduce the flow of water. How much water can you save? Read more
