crycry Posted January 12, 2017 Report Share Posted January 12, 2017 Hi, I'm junior but I already started do my practice IA. My IA topic is looking at the relationship between the diameter of hydraulic jump and the pressure of water. To elaborate, hydraulic jump is the circle you can see on the surface of the sink when you open the tap water. If the pressure of water increases, the diameter of the circle also increases. I'm using a burette to drip the water and I measured the diameter of the hydraulic jump when the water left in the burette was 50mL, 40mL, 30mL, 20mL, 10mL. Hope it helps!

nadi0987 Posted January 29, 2017 Report Share Posted January 29, 2017 HI. My research question is: How does the length of a wing from a paper helicopter affect the time it takes for it to get to the ground?. You can do something with the flight of an object. I'm changing the wings length by adding 10 mm more. Hope it helps! Reply Link to post Share on other sites More sharing options...
