How does temperature affect viscosity?
To observe a chemical reaction between an acid and a base. If making a large quantity of lava lamps you can order soda bottle performs in bulk at through a vendor such as: The long chains of carbon that make up oils do not carry a charge and are not attracted to the water molecules.
This causes the separation we see in this experiment as well as in our kitchen sinks and oceanic oil spills. Furthermore, the oil will float on top of the water because it is less dense than oil.
Alka-Seltzer is technically both acidic and basic. The tablets contain sodium bicarbonate a base and citric acid an acid which, when mixed with water, react with each other and produce bubbling carbon dioxide.
This creates the bubbles you see within the colored fluid in the soda bottle. Research Questions What happens when you add water to the plastic bottle?
Why do you think this occurs? What happens when you add the food coloring to the bottle? What happens when you add the Alka-Seltzer to the bottle? What experiments did you perform on the closed soda bottle twisting, shaking, etc.
What did you notice during each trial? Terms, Concepts and Questions to Start Background Research Oil and water mixture — Oil, a hydrophobic compound, and water, a hydrophilic compound, do not mix.
See detailed discussion in Introduction section. Acid-base reaction — A chemical reaction between two substances where one is an acid and one is a base.
Gather materials over a surface that cannot be damaged by oil or can be wiped clean. Another good option is to cover a table with old newspapers. Add water to the neck of the bottle, leaving a little space between the water line and the top of the container.
You can always add more water at a later time. Select the food coloring accordingly. Add 10 or more drops of food coloring to the bottle until a rich color is seen. Break the Alka-Seltzer tablet into smaller pieces 6 to 8.Science Fair Project Ideas.
timberdesignmag.com has assembled a vast collection of science fair project ideas written by science teachers, professional scientists, and educational consultants on popular science fair topics ranging from physics and chemistry to biology and even sociology.
Join us in sharing your best idea using science, technology, engineering, and math. This project is not going to win any fair, but if you are in a jam and just need SOMETHING and a decent grade, then this project might help: Science Fair Project in One Hour.

Could we please agree to actually read the whole post and the updates before commenting? All commenters welcome, and I never delete comments except in the case of outright advertisement spam This is a project my son did for Science Fair . Once you have your data, you will need to present it to your teacher and science fair judges.
In a science publication, you would choose between a table and a graph, but for the science fair project it is acceptable, and even encouraged, to showcase the data in both forms. Aug 28, · How to Create a Science Fair Project.
The science fair is an integral part of education. Science fairs allow you to understand and practice the scientific method on any topic that you are interested in.
