Science Y3/Y4 – Weather – week 11

WEATHER – HAIL, SLEET, SNOW, FROST, DEW

Truth to Teach (Source)

To learn that water moves from the atmosphere to the earth’s surface in many forms.

The way in which water falls depends largely on the air temperature.

To appreciate the uniqueness of each snowflake and the aspect of God’s character in creating
each of us individually.

Way to Work (Means)

1. Review the water cycle and other lessons from this half term.

2. Ask the children if they can think of other ways in which water comes onto the earth,
other than as rain (dew, hail, sleet, snow, frost).

3. Show a thermometer and ask the children what temperature they think the air has to be
before we get snow and/or frost (0 degrees or below).

4. Discuss what hail is – hailstones are raindrops which move back up into the cloud on rising
air currents, and freeze into solid balls of ice.

Amazing fact: In 1970 a huge hailstone fell in Kansas, USA which was 19cm across and
weighed 750 grams.

5. Show a snowflake cut from paper and ask the children what is so special about a
snowflake. (Each has six points but is unique). Compare this to God’s creation of humans.
Let the children make a snowflake of their own then gather back to compare them all.

6. Talk about the effect frost has on our windows, roads, etc. Show the children two small
bottles, one which has water in it and one which had been put in the freezer a while ago
and has frozen. The water will have expanded over the top of the bottle as ice takes up
more space. Let the children consider the effect of ice in cracks on a road or pavement.

7. Let the children complete the worksheet then create a snowflake picture with lots of
different snowflakes.

Learning for Life (Fulfilment)

The children will hopefully see the wisdom of God in creation again. They will also see the effects
that the weather has on our environment.
