A science project is an education activity or experiment conducted by students, usually used to teach or enforce a science concept. A science project can also be entered into school and community science fairs. Students can perform various science projects using many different household items, such as a cookie sheet.
Variations Between Different Cookie Sheets
Students can try to figure out the variations caused by using different cookie sheets to bake cookies. There are several types of cookie sheets, with those made of aluminum, steel, insulated and nonstick materials being the most common. For younger students, the science project can simply look at which cookie sheet works best for various types of cookies, or for older students, the focus can be on what causes uneven baking between the different types of cookie sheets. Students can look at the composition of the cookie sheets and determine if the metal composition conduct heats at various rates, and whether the various types heat up evenly.
Slick Sliding Soap
Students can conduct a slick sliding soap project with a cookie sheet. Using a dry bar of soap and any type of cookie sheet, students can try to determine what makes soap slide down. Friction is the primary lesson being taught with this project.
To perform the experiment, students take a dry bar of soap and using various substances such as lotion, water, cooking oil, orange juice, milk or cooking grease, one at a time, they grease the bar of soap with the substance. Then, they tilt an ungreased cookie sheet at about a 15 to 20 degree angle, see if the bar of soap slides down the cookie sheet and how far it goes.
A science project good for young children using a cookie sheet is crystal growing. The simplest way to make crystals is by combining Epsom salt with hot water. Epsom salt can be found in most grocery or drug stores in the medicine aisle. Students take 1/2 cup of Epsom salt and 1/2 cup of hot tap water and mix them together in a bowl. If they wish to have colored crystals, they can add a few drops of food coloring to the mixture. Then students stir the mixture for one minute, pour the mixture evenly onto a cookie sheet and place it on a flat surface in the refrigerator for 3 hours. After 3 hours in the refrigerator, the mixture will produce thin needle crystals.
