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.
