A force is something that pushes or pulls on something else. When you throw a paper plane in the air, you are giving the plane a push to move forward. That push is a type of force called thrust. While the plane is flying forward, air is moving over and under the wings and is providing a force called lift to the plane. An abstract is an abbreviated version of your science fair project final report. For most science fairs it is limited to a maximum of 250 words (check the rules for your competition).

You will need to make and quickly measure only one popping boba ball at a time, because the balls can change over time. The tip of the syringe should be around 8–13 cm (3–5 inches) above the surface of the solution. Figure 5. Drop a single drop of the food solution into the calcium chloride solution, as shown here.Holding the spoon with the yogurt just above the sodium alginate solution's surface, carefully scoop the yogurt out (using a second spoon) so that it stays together as one whole blob in the solution. Clean out the measuring spoon and repeat steps 4.a.–4.e. two more times to make a total of three samples.1 roll of tape (1×5 points = 5 points) Plug your distance in centimeters and total material points cost into Equation 1 to calculate your score. For the car in the example above, with a distance of 25.4 cm and a material points cost of 31, the score is (2×25.4)-31 = 19.8. Round your final score to the nearest whole number.A lab notebook is an important part of any research or engineering project. Used properly, your lab notebook contains a detailed and permanent account of every step of your project, from the initial brainstorming to the final data analysis and research report. Many science projects require a number of steps and multiple trials.Global warming is the increase in the average temperature of Earth's air and oceans. Global warming since the 1950's is thought to have been caused mainly by things that people do, like burn gas to drive cars, burn coal to make electricity, burn oil or natural gas to heat homes, or burn forests to make room for growing crops.

Melanin is what turns the fruit and vegetables brown. This reaction, however, usually does not happen within fresh fruits and vegetables because the PPO and the phenolic compounds are separated in produce plant cells. The enzymatic browning process is only triggered when PPO, phenolic compounds, and oxygen come in contact with each other.
