Migration of Monarch butterflies and global warmingFeatured science projectScience project video


The materials required for this science fair project:
- 4 transparent fish tanks
- 40 Monarch butterflies
- 1 spray bottle
- 1 liter of tap water
- 1 cold storage room


1. For this science fair project, the independent variable is the exposure of the Monarch butterflies to sprayed water and cold temperature. The dependent variable is  whether the butterflies survive or die. This is determined by observing the butterflies at the end of the science project experiment. The constants (control variables) are the number of butterflies, the amount of water sprayed on the butterflies and the temperature of the cold storage room.

2. The 4 fish tanks are labeled A, B, C and D. Each fish tank is filled with 10 Monarch butterflies.

3. Water is filled into the spray container.

4. On the first day of science fair project, all of the Monarch butterflies in all the 4 tanks are sprayed with water. The wings of the butterflies must be wet thoroughly. This is to simulate  rain. After being sprayed with water, the butterflies in each fish tank are exposed to the following conditions :

a. Tank A – the butterflies are allowed to dry out at normal room temperature,

b. Tank B – the butterflies are kept inside the cold storage room for 2 hours,

c. Tank C – the butterflies are kept inside the cold storage room for 1 day, and

d. Tank D – the butterflies are kept inside the cold storage room for 2 days.

The purpose of the cold storage room is to simulate cold weather that comes after the rain.

5. The Monarch butterflies are observed for  3 days to see if they are alive or dead. The number of butterflies alive on each day is recorded in the table below.
