Science Fair Ideas - Earth & Space

• Are snowflakes all the same?
• Why is the sky a different colour at different times of the day?
• Study and record how clouds relate to weather patterns. 
• Does wind travel at same speeds and in same directions at different heights? 
• Measure the speed and force of raindrops when it rains
• Which factors affect the rate of evaporation the most? Temperature, humidity, wind speed or other factors? 
• Does fresh water hold heat from the Sun longer than salt water?
• How does water temperature compare to land temperature at different times of the day?
• What affect do different surfaces have on the amount of sunlight reflected and absorbed?
• Design a method of measuring how much sunshine is available each day.  Perhaps a good PICAXE project?
• Design and build an automatic recording weather device. Test it over a period of time. Perhaps a good PICAXE project?
• Design and build a refracting or reflecting telescope. See our Sun Gun.
• Build a model solar system with levitating planets
• Lunar Lander game - use nothing but air to steer a spaceship to safety
• Collect micro-meteorites
• Collect fossils and identify them. Work out the recent geological history of your area.
• Observations of experimentally induced seismic waves. 
• Is there a relationship between the Lunar cycle and Earthquakes?
• Explore methods of controlling erosion 
• Observations of local anomalies in the earth's magnetic field 
• A study of phosphorescence as a tool for geologists 
• Comparison of the load bearing strength for different soils 
• Study of air tides: phases of the moon versus barometric pressure 
• Effects of weather on human emotions 
• Study of the relation between wind direction and temperature inversions 
• A study of small scale wind currents around school buildings (where does the litter build up?)
• Launch a rocket with sensors to gather data from high altitudes.
