Effectiveness of ginger against motion sickness
The materials required for this science fair project:
- 10 participants
- a 5 meter long straight sidewalk
- 1 box of chalk
- 1 measuring tape
- a stopwatch
- 1 bag of ginger candy
1. For this science fair project, the independent variable is whether the participants are given ginger candy or not. The dependent variable is the time taken to walk the straight line. This is determined by using a stopwatch to measure the time. The constants (control variables) are the number of time the participants are made to spin before walking, the distance, and the number of ginger candies eaten per participant.
2. Using a piece of chalk and the measuring tape, draw a straight 5 meter-long line on the sidewalk with the help of an assistant. The width of the line should be about 50mm.
3. Ten participants are made to walk on the line the full 5 meters and then turn back to walk another 5 meters. The time taken by each of the 10 participants to walk the 10 meters is recorded in the table given below.
4. The participants are next made to close their eyes, stretch out their hands side ways and turn around 20 times. This will be done one participant at a time. The assistant will stand beside the participant to ensure that he does not fall due to giddiness.
5. After a participant has completed the 20 spins, procedure 3 is repeated and the time taken to walk the 10 meters is recorded in the table given below.
6. After the participant has completed the 2nd walk, he is given 10 ginger candies to eat. About 30 minutes after he has eaten the ginger candy, procedures 4 and 5 are repeated and the time taken by the participant to walk the 10 meters is recorded in the table below.
