Lesson Worksheet: Modelling the Water Cycle Science

In this worksheet, we will practice modelling the water cycle using the solar still model

Q1:

After 24 hours, the water level in the solar still model goes down.

What process causes this to happen?

  • AEvaporation
  • BPrecipitation
  • CCondensation

Q2:

Look at the picture of the solar still model. After 24 hours, the water evaporates.

Which part of the model gives off heat and makes the water evaporate?

  • AThe small cup
  • BThe water
  • CThe Sun

Q3:

A student set up a solar still model and put it outside in the sun. There was no water in the small cup. After 24 hours, there was water in the small cup, as shown below.

What process causes the water to enter the small cup?

  • AEvaporation
  • BPrecipitation
  • CCondensation

Q4:

Look at the different steps of the water cycle.

Which table shows the correct states of matter of the water cycle?

  • A
    123
    SolidGasLiquid
  • B
    123
    GasGasLiquid
  • C
    123
    LiquidSolidLiquid
  • D
    123
    LiquidGasLiquid

Q5:

Which pictures are labeled correctly?

  • A
  • B
  • C
  • D

Q6:

Look at the solar still model of the water cycle.

What process is shown by the solar still model?

  • APrecipitation
  • BCondensation
  • CEvaporation
  • DAll of the answers are correct.

Q7:

The solar still model can be used to show the water cycle.

Fill in the blank: After 24 hours in the Sun, the water level has .

  • Agone down
  • Bgone up
  • Cstayed the same

Q8:

Look at this picture of the solar still model.

Fill in the blank: In the solar still model, when the water evaporates, the salt .

  • Ais left behind
  • Bevaporates too
  • Cturns into a gas

Q9:

Look at this picture of the solar still model and think about what happens after 24 hours in the sun.

Fill in the blank: There is salt in the water outside the cup than in the water inside the cup.

  • Aless
  • Bmore

Q10:

Look at the solar still model.

Which number points to precipitation?
