The hypothesis is that the javelin will travel the furthest when thrown at 45°.

You will need to set up a football field, get 3 javelins, 3 athletes trained in javelin throws, a 100 meter measuring tape, a DVD video-recorder, a DVD disc, a portable DVD player with screen, an assistant, a cameraman, and a protractor. The athletes will attempt 5 throws each at 20°, 25°, 30°, 35°, 40° and 45° angles.

You will need a football field, 3 javelins, 3 athletes, a 100 meter measuring tape, a DVD video-recorder, a DVD disc, a portable DVD player with screen, an assistant, a cameraman, and a protractor.

The results showed that the distance achieved for each javelin throw peaked at the release angle of 35°. This was true for all 3 athletes. The hypothesis that the javelin will travel the furthest when thrown at 45° was proven to be incorrect.

This science project is interesting because it tests a very old athletic event that has been around since the 8th century. It also tests the aerodynamics and biomechanical principles involved in javelin throwing.

Variations of this experiment could include repeating it with a discus and shot putt, or repeating it with athletes of different heights.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
