Start with asking about water around us - what do students see/know about?
From their starting point, ask where that water came from, then work backwards, to include all stages of the water cycle, writing/drawing up each stage as it is added. Students may well include water from taps and in man-made structures. These are part of the water cycle in a city.
Relate the states of matter to the water cycle: water in the lakes and oceans evaporates (liquid to gas) and goes into the air. When it gets high enough it cools and condenses (gas to liquid) to form clouds. When the liquid drops are heavy enough, they make raindrops that fall as rain or snow (precipitation). The snow on mountains will melt if it is warm enough, as we see on our Northshore mountains every year.
Optional side activity: States of matter in water.
If using the worksheet, hand them out (attached, and image).
Students write the words in the correct spaces.
Do a selection of these activitites:
Water cycle model:
Set up the optional water cycle model while students are filling in their worksheets. Look at the water cycle model together when all the worksheets are done. Relate what is happening in the model to the steps of the water cycle.
Water cycle bracelet:
If the water cycle bracelet is included in the lesson:
Students use the bracelet materials to make a short bead chain and tape it next to the words on the worksheet.
Alternatively, add a dot of colour next to each word, making sure the colours used are the same as the bead colours in the bracelets.
Erosion activity:
The erosion activity models what happens as the water flows down mountainsides to the ocean.
Posting game:
Active posting game recognizing and matching water cycle words.
Research project:
Look at old maps to find out where the original streams flowed, which are now under the concrete of the city. For Vancouver, see https://www.hiddenhydrology.org/vancouvers-secret-waterways/
