Common questions & answers relating to science fair projects.
Q: What concentration of bleach is use to kill mold?Amber A: This site is all about teaching you how to find the answers yourself. So lets begin there: In the google search window input the keywords, “concentration of bleach to kill molds” and whala – tons of answers. From my search I found out that […]
Question Hi Madeline, My son and I are working on putting together his PicoTurbine Windmill for his 4th grade Science Fair. I am not sure if you are intimately familiar with this project, but I have a question… We have been able to get the expected 1.5-2.0 volts from the turbine by checking the output […]
Question: How would I measure sugar concentration in apple juice in different brands of apple juice. Answer: According to the wine doctor.com the refractometer is a device in which the juice from a wine grape is squeezed into and then provides a sugar reading of the juice content. Another method, according to the wine doctor, […]
Question: I am studying in BSc electronics. I am participating in Science Project exhibition this time. I came to know from my friend about your website which is really knowledgable for our age science students.I am interested to buy one of your Pico-turbine and DC experiment KIT. Is it possible to deliver it to UK […]
Question: My daughter is trying to do an experiment using pectin enzyme to remove juice from apples and it is not working here is the question if someone would be able to assist her project is due in one week. I am Extracting Apple Juice w/Pectinase. I have followed the Experimental Procedures and I am […]
Question: This question came from a 13 yr old student. Answer: The answer to her question is yes. Many chemical reactions will increase proportionally to the surface area of the particle. The more surface exposed, the faster the reaction can occur. An example that comes to mind; mixing Alka Seltzer with water […]
Madeline, I forgot to ask this question earlier. My daughter noticed that the whirl-pak bags did not have T-salt tablets in them. The identical ones we used last year supplied by the local utility had tablets. I know it’s for de-chlorination purposes to preserve bacteria in the water samples. Just need your feedback on this. Thanks. […]
Question: Dear Madeline Some time ago you had something in one of your newletters about a science fair project dealing with chocolate. (coffee, cacao etc.) that one can use. Is it possible to forward the information to me. We would like to do something along that line for our next project. My Child is 12 […]
Question: hi, I need ideas for any science fair project to do with laser’s i’m in grade 8 and i will take any suggestions thanks Answer: The magnetometer uses a diode laser – open-style laser pointer to measure the interplanetary magnetic field. It is a device that you build yourself and has helped many students […]
Question from Sydney: Dear Super Science fair projects.com, I am a ninth grade girl and I need a science fair project idea. I love the environment, and I wanted to do something to show how plastic bags effect the environment, but I cannot think of any ways to test that. We are using the scientific […]
Building in 1 Direction: The rods can be connected in-line without the intermediate need of a connector, almost reducing to half the quantity of parts required to build models.
Building in 2 Direction: While the assembled rod looks uniform with nothing protruding, it may provide building directions vertically and sideways by simply snap fitting another rod to one of the bi-directional side cavities. This innovative design allows snap assembly on both sides simultaneously and greatly enhances the expandability of the System.
Building in 3 Directions: The System is capable of tackling with the same ease as all the other building directions. All directions of the 3D space are accessible by combining the rods with the various types of connectors.
Connecting in Fixed Angles: This system makes it possible to build complex models that require connections of 45°
Building Machines: The optimized design of Engino components consists of only 18 different types of multi-functional parts. Yet you can build simple and complex machines. Following the same design principles of the basic system, a range of different types of gears, pulleys, axles and accessories make it the ideal constructional toy for home and school.
