Reeko's Mad Scientist Lab v. Your source of free science experiments for parents, teachers, and children of all ages. As you'll soon find out - nothing is ordinary around here. Millions of years ago, there were some dinosaurs that could fly, but they became extinct long before man lived on earth. When something glides, it floats through the air without using power.
True flight requires energy to move wings up and down.
Keep track of distances covered and elapsed times. A wide variety of plots allows you to monitor your progress toward established goals, whether it be weight loss or a desired 10K running time. Plots show individual and cumulative workout distances, elapsed time, calories burned, and pounds lost. Trend lines predict where you will be at an established goal date. Rate plots show your speed during workouts and how long it takes for you to cover some selected distance.
