Term 2 Science ACE

In May, I did my first science ACE, here is the detailed plan of my ACE…        
Aim: To find out if the level of ph. of a fruit affect its ability to conduct electricity

Apparatus and Materials Needed: Lemon (Juice), Orange (Juice), Apple (Juice), Purple Cabbage, Batteries, Light Bulb, Wires, Datalogger, Beaker

   Steps (To find if the level of ph. of a fruit affect its ability to conduct electricity)

1.      Extract the juice from the lemon, orange and apple

2.      Place the juice of these 3 kind of fruits into 3 individual cups

3.      Connect the wire to the light bulb and batteries 

4. Connect the 2 ends of the wire to the fruit juices, each at a time and record the brightness
 

  

 






Steps (To find the acidity)

1.         Cut the purple cabbage into strips

2.         Boil the cabbage until the juice is extracted

3.         Take the blotting paper and soak it in the purple cabbage juice and let it dry

4.         Soak the blotting paper into the beaker of fruit juice and record the colour of the blotting paper

5.         Repeat step 4 on the other 2 beakers

6.         If the blotting paper turned red, the liquid is an acid. 

7.         If the blotting paper turned green, the liquid is an alkalis

8.         If the colour of the blotting paper remain unchanged, then the liquid is neutral
