Revised experimental procedure

Since I have to set up two set-ups testing the same frequency at one go, I have revised my experimental procedure.

Materials and apparatus

1. Artemia (Brine Shrimp) eggs
2. Macbook with the app, Tone Generator X
3. Hands lens
4. Counter
5. 2 transparent beaker
6. 160g of sea salt
7. Boiled water
8. Science journal

Procedure

1. Place 2 beakers in a semi-lit room
2. Pour 1000 ml of boiled water into each beaker
3. Add in 20g of sea salt into each beaker
4. Place the speaker of the Macbook directly above the mouth of both beakers
5. Switch the software, Tone Generator X, on to 186 Hz at the volume level of 80%
6. Add in half a teaspoon of Artemia (brine shrimp) eggs
7. Check the set-up with a hands lens at every 12-hour interval and use the counter to count the number of eggs that have hatched
8. Record down in my journal the number of eggs that hatched
9. Repeat steps with 171 Hz, 259 Hz and 223 Hz
