The First Experiment: Balloon Release (Planning)

Maria is still learning to read and write, so for now I will be typing for her.


We will be using this model of the scientific method for our experiments.

1. Define the question
2. Gather information and resources (observe)
3. Form hypothesis
4. Perform experiment and collect data
5. Analyze data
6. Interpret data and draw conclusions that serve as a starting point for new hypothesis
7. Publish results
8. Retest

For our first experiment, we will release some balloons with notes on them to tell whoever finds them how to contact us. We will try to predict where they will end up.

In our research, we have learned that when you let a balloon go it will get bigger the higher it goes in the sky, and eventually it will pop and fall back to the ground. 

Variables effecting how far a balloon will travel:

1. Wind and weather
2. Thickness of balloon
3. How much Helium the balloon starts with

Our level of experimentation makes it difficult to get the data we need to more accurately predict how far our balloons will travel, so we will modify our experiment at this point. We will release two sets of balloons, one set inflated fully and the other inflated half-way or just enough to rise with it's payload. 

Our hypothesis is that the half-inflated balloons will be able to rise higher in the sky, and that will give the wind more time to blow them farther away before the air pressure pops them. So we expect the fully inflated balloons to be recovered closer to the release point than the partially inflated balloons.

We will use this Google Map to record data. We will record the wind speed, direction and temperature at the time of release.

To increase the chances of the balloons being recovered and reported by helpful people, we are considering several options:

1. Using brightly colored paper for the notes, so they stand out more.
2. Attaching small, battery powered lights that flash to attract attention (this might not be legal, and will require further research).
3. Paint pictures and send with them. Could increase willingness to respond.

Supplies we will need:

1. 12 helium balloons, 6 fully inflated, 6 partially inflated.
2. 12 brightly colored notes with blog URL and unique drawings from Maria.
3. Plastic holders for notes to protect against water damage.
4. 12 LED beacons (maybe).
5. Google Map to record release and recovery data.

We will post a new update when we have performed the experiment!
