From Dull to Dazzling: Using Pennies to Test How pH Affects Copper Corrosion

Science Fair Project Idea

Scientific Method

Pennies are bright and shiny when they are new, but become quite dull with time. What causes such a drastic change? Oxygen in the air combines with the copper in the penny to form copper oxide, which makes the penny look dull and dingy. You can make the pennies look like new again by soaking them in water that is corrosive enough to strip off the copper oxide layer. It turns out, however, that the same process that makes the pennies shiny has bad consequences when it comes to copper pipes: it… Read more

Water from Air: Experimenting with Dew Traps

Science Fair Project Idea

Scientific Method

Most of us live in areas where sources of water exist nearby as oceans, rivers, lakes, ponds, streams, reservoirs, wells, or even underground streams. But in some places, like the desert, water is hard to find and a precious resource. In this environmental engineering science project, you will investigate one way that people living in arid regions can collect water inexpensively: dew traps. Read more

Which Type of Water is the Hardest?

Science Fair Project Idea

Scientific Method

Do you want your hair to be shiny after you wash it? Do you want your clothes to stay bright and soft after laundering, and last a long time? You might think that a special shampoo or detergent can make this happen, but in this chemistry science fair project, you'll discover that how well people and things get clean has a lot more to do with the type of water used for washing than any special shampoo or soap. Did you know that water can be classified as either soft or hard? Soft water lathers… Read more

Chemical Analysis of Rainwater

Science Fair Project Idea

Scientific Method

Here is an interesting project that could be approached from several different scientific angles: Environmental Science, Weather & Atmosphere, Chemistry, or Plant Biology. You can probably think of your own variations to emphasize the scientific area that most interests you. Read more

Underground Water Flow and Darcy's Law

Science Fair Project Idea

Scientific Method

This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and cave formation. With your model system, you can simulate various underground conditions, and test your predictions about the effects they have on water flow. Read more

Water-Wise: Building a Rainwater Collection System

Science Fair Project Idea

Scientific Method

We are all familiar with the nursery rhyme, "Rain, rain, go away, come again some other day...", or the song "Singin' in the Rain." Numerous songs and stories describe our feelings about rain. Why so many? Because we humans understand how important rain is to our well-being. Rainfall, as part of the water cycle, brings water back to Earth that had previously evaporated or transpired from the surface. When water vapor in the atmosphere condenses into clouds and falls back to Earth as rain,… Read more

Can Water Plants Be Used to Determine Water Quality?

Science Fair Project Idea

Scientific Method

Some plants grow only in water-logged environments. These plants are usually native to wetlands and are important for the sustainability of aquatic ecosystems. Wetland ecosystems are very fragile and susceptible to the toxic dumping of sewage and fertilizer run-off from neighboring farm land. One very common aquatic plant called duckweed inhabits many wetland marshes. Duckweed grows by asexual reproduction and floats at the surface of the water with tiny roots extending into the water below.… Read more

From Your John to the School Lawn: Is Recycled Water Really Safe?

Science Fair Project Idea

Scientific Method

Reclaimed (treated) wastewater can be used for many purposes, including landscape watering and freeing up valuable fresh water for other purposes (like drinking water). It's a great way to conserve water, but is it really safe? This science fair project is designed to find out. Read more
