Use TesTab Dissolved Oxygen/BOD Kitinstead of lab protocol. Use a dissoved oxygen tank meter. Once samples are fixed, they can be stored in refrigerator for titration later. Expand study to include natural water bodies (lakes, ponds, etc.). Have students conduct a seasonal study of these water bodies. Remember that science lab kits can be […]
Teachers, see the biology lab tips for transpiration, especially if you are teaching AP classes. Use house plant if bush beans are not available. Cut plant stems and insert stem into tubing while stem is submerged in a pan of water. This prevents air gaps from forming in xylem vessels. Buy disposable glass pipettes (and […]

Kay’s science fair project on temperature and electricity shows the effects of metal as a conductor of electricity as well as affects of temperature. Temperature and Electricity Abstract CATEGORY: Physics STUDENT: Kay Many factors are known to affect how well a metal conducts electricity. Temperature is one factor that affects the resistance of a conductor. […]
See the engineering science fair project on indoor air quality that you can do in regards to buildings that do not have windows that open. Name: Divyansh Grade: 12 Age: 17 New Delhi, INDIA Category: Environmental Science Awards Selected for Iris (Initiative for Research and Innovation in Science) at the National Level Won the 3rd […]
9th grade is usually the first year that students are able to explore specific fields of science in detail. They can elect to take Biology, Chemistry, Physics or Earth Science. This branching off of science interest allows the student to really explore their areas of interest. However, it also provides them the opportunity to learn […]
The Science Daily reported that human-driven changes in the earth’s atmospheric composition are likely to alter plant diseases of the future. Researchers predict carbon dioxide will reach levels double those of the pre-industrial era by the year 2050, complicating agriculture’s need to produce enough food for a rapidly growing population.

Scientist believe that the universe started as a “perfect” liquid when the Big Bang occurred. What is the Big Bang? Cosmologists use the term Big Bang to refer to the idea that the universe was originally extremely hot and dense at some finite time in the past and has since cooled by expanding to the […]
The Diffraction of Light science fair project abstract shows you what determines the percentage of light that is defracted. Edward Age 16 Kentucky, United States of America Abstract The percentage of light reflected from objects to another object, will vary depending on the angle of the light source and how much the light is diffused. […]
Above Anatomy of an infographic by spyrestudios.com Often times it is difficult to put all the pieces together in sequential order and to see the whole picture of what a science fair project is all about. The science fair project infographic cheat sheet does it for you! It gives you a step-by-step process and presents […]
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.
