Atomic modeling with food particles
In this science project, you are going to use different types of dried beans like pinto, kidney, and great northern beans to represent protons neutrons and electrons. You will select 5 atoms per group and proceed to build models of these atoms on paper plates using Elmer's glue. You should also include ions and isotopes as variations of these atoms.
Difficulty
Can we create light by chewing?
Certain chemical bonds will generate light energy when the molecules are torn apart by mechanical crushing. Wintergreen Lifesaver candies contain some of these bonds. No other flavor of lifesaver candy (such as peppermint) will work in this experiment.
Difficulty: Elementary school
Can you demonstrate why the sky is blue?
The scattering of light by the atmosphere, which creates the blue sky and red sunsets, can be modeled when light from a flashlight shines through clear glue sticks.
Difficulty: Middle school
Color and depth of water
This experiment was conducted to determine how the depth of water can affect the visibility of colors. The experiment was done by taking photos of various colored balls (i.e. red, yellow, green, and blue) at depths of 5 meters, 10 meters, 15 meters and 20 meters underwater.
Difficulty: High school
Comparing the effectiveness of a light sensor and a touch sensor
This experiment was conducted to compare the effectiveness of using a light sensor and a touch sensor on a conveyor belt. The experiment was done by using a light and touch sensor to count the number of boxes on a conveyor belt.
Difficulty: High school
Demonstrate how satellites measure the amount of energy reflected from the earth
Satellites are used to monitor the condition of the earth's surface over large areas in a short time period. Images from satellites have been used to determine changes in global vegetation patterns, monitor the health of agricultural crops, and measure the amount of evaporation from the earth's surface. The pictures from satellites are not taken with a traditional camera that requires film. Instea

Diffusion of Helium gas in latex balloons
This experiment was conducted to ascertain how air pressure affects the rate at which helium gas escapes from latex balloons.
Difficulty: Middle school
Does the viscosity of liquids affect the shape of droplets?
This experiment involves the observations of different shaped drops of liquids of varying viscosities. The purpose is to observe and compare these different forms. The hypothesis is that the liquids with the higher viscosities will form longer necks on their drops than the liquids with lower viscosities.
Difficulty: Middle school
Drumstick material and rebound characteristics
This experiment was conducted to investigate whether the material used to make a drumstick affects its rebound height. Drumsticks of four different makes were used: the drumsticks were made from titanium, aluminum, hickory or oak.
Difficulty: Middle school
Effect of temperature on magnets
This science fair project was conducted to find out how temperature affects the strength of a magnet. The tests were done using 5 permanent magnets at 0 degrees Celcius, 25 degrees Celcius, 50 degrees Celcius, 75 degrees Celcius and 100 degrees Celcius.
Difficulty: Middle school
