Can we make it rain indoors?

Thursday 17 January 2019

Many thanks to all who came to watch our assembly on Wednesday. The children showcased their learning impressively. Despite a technical hitch, the children remained calm and were able to sing their song without the backing track.

In Science, we’ve been learning more about the water cycle and some tricky scientific vocabulary. To help  secure good understanding of the new words, Year 4 created their own glossaries. After putting the words into alphabetical order, the class then added definitions.

Question: How can you make it rain indoors?

This afternoon, we thought about this question and came up with some ideas of how we could go about finding out whether or not we could make it rain inside.

What You Need:
• An empty glass jar with a metal top
• Hot tap water
• Ice cubes

Tip: Be patient. It takes about 15 minutes for water drops to form.

1) First, fill a glass jar with very hot tap water.
2) Then, place a plate over the jar and fill it with ice.
3) Now, wait and watch. In about 15 minutes you will see “rain” fall inside the jar .

What will happen?

“The hot air will rise and cool down.”

“When the water vapor reaches the cold plate, I think we will see droplets of rain.” 

“The hot water will turn into steam.”

“The ice will cool the steam and turn it back into a liquid.” 

” This process is called condensation.”

Were we correct?

YES!

Inside the bowl, we began to see water droplets falling . Image result for make it rain inside experiment

Question your child about these images. Can they tell you what is happening using some scientific vocabulary?
