Seashells are the hard, outer coverings that mollusks produce, in order to protect themselves from predators; it also serves as a form of shelter form the elements. Seashells come in a wide range of shapes, sizes, and colors; however, they all are created from the same material - calcium carbonate. In this science fair project, you will investigate how seashells, and other objects containing calci

Fast food is very popular as evident by the number of fast food chains in our neighborhoods. But does the convenience that fast food offer come at a cost? In this science project, you will be conducting a survey to understand "fast food habits", and you will also examine the nutritional vale of these meals.

While most of us do not give much thought to water quality, serious aquarists are keenly aware of the importance of maintaining water quality. But while aquarists are careful to maintain ph, nitrates, and ammonia levels, many do not give the same attention to the level of dissolved oxygen (DO). An understanding of the relationship between temperature and DO is the subject of this science project.
Difficulty
Cooking is critical for our diets, as it helps us digest certain foods that may not be as gentle on our stomachs (easily digestible) in their raw form. Although proponents of healthy diets will often promote raw fruits and vegetables as being the healthiest, this may not always be the case. For this science fair project, you will determine whether cooking depletes or in fact concentrates the amoun

Convection is the phenomena characterized by the movement of molecules in gases and liquids. Heat causes molecules to be active, while cooler temperatures result in less activity. Convection can be observed in volcanoes, in the ocean, in cooking, in heating your home and even in decorative lava lamps. In this science fair project you will observe how the addition of salt to water effects convecti

As environmental science students, we need to learn the importance of minimizing the impact of our actions on the world around us. Did you know that when miners drill into or strip the earth to obtain ore or fossil fuels, they can cause great environmental harm? In this science project, we will be operating our own "mine" to understand how mining can damage our environment . We will be mining "
