April Science Challenge
Get involved in our April Science Challenge - Making a water gauge.
- Empty plastic bottle
- Permanent marker
1. Cut the top of the bottle off, and place it upside down in the bottom of the bottle (ask an adult for help with this as the bottle can be sharp).
2. Place a ruler on the side of the bottle and use the permanent marker to mark each CM on the side of the bottle.
3. Bury the bottle outside (it should be in an open area and away from any trees which can trap some of the rain). Leave the top of the bottle sticking out.
*The important part is recording the rainfall frequently. You should record the amount of rain in the bottle each day and then empty out the rain each time. Can you design a table to record the results?
Rainfall is part of the water cycle. The sun heats up water on land, in rivers, lakes and seas and turns it into water vapour. Water vapour condenses into clouds by cooling down and changing back into tiny droplets of liquid water, forming clouds. The clouds get heavy, and water falls from the clouds back down to the ground either as rain or snow. The rainwater runs over land and collects in lakes or rivers, which take it back to the sea. The cycle then starts again.
Scientists of the Month
Our scientist of the month is Jane X. Luu.
Can you write some facts about this amazing Scientist?
