Hands-On Science: Water Cycle in a Baggie

3rd graders have carried out an experiment on the water cycle. They made it rain inside a baggie.
Steps:
1- Draw a simple design on a Ziploc baggie: sun, clouds, ocean waves…even a submarine! Use a permanent marker.
2- Open the bag and fill it just a little bit with water. Try keeping it off the edges!
3- Add some blue food colouring and seal up the bag.
4- Hang the baggie on the window and see it in action!

Hands-On: Properties of Water

3rd graders carried out an experiment in the laboratory to find out about some basic properties of water: water is colourless (it has no colour), odourless (it has no smell) and tasteless (it has no flavour). They had to compare a glass of water and a glass of orangeade by looking at both liquids, smelling them and tasting them. Then they poured a bit of oil in the water and observed what happened: oil and water don’t mix because water is heavier than oil!
