BAGI SEBAB kpd PEMERHATIAN
- Brightness of the bulb
length of wire OBSERVATION
InferenceOBSERVATION
AND
WHY
Situation A produce more friction It’s have rough surface
Responding Variable
FRICTION
Manipulated variableTYPE OF SURFACE
BECAUSE WHY
Hypothesis
The … M.V, The….. R.V ….= larger, bigger, more, longer,
brighter, dimmer, higher, greater,lower, rougher, thicker, smaller

- The higher the density of the medium, the smaller is the weight of object X
- The lower the density of the medium, the greater is the weight of object X
Hypothesis
The longer the wire, the dimmer the bulb.
The shorter the wire, the brighter the bulb.
Factors Affecting the Rate of Transpiration
Manipulated variables
Responding variables
Fixed variables
1. LIGHT2. TEMPERATURE3. WIND4. HUMIDITY
Light, Temperature, Humidity, timesize and type of plant
Presence of wind
Rate of transpiration / difference in weight of the apparatus
Hypothesis – Windy condition increases the rate of transpiration
Observation The water loss is more for the
potometer that is subjected to wind.
Conclusion
The rate of transpiration is faster if wind is present.
