Hi,
My name is Chloe and I will be teaching senior infants in September.
My favourite space fact is that it would take 9 years to walk the moon.
Mind map: galaxy, stars, planets, orbit, moon, solar system, sun, satellites, exploration, gases, cool, heat, gravity, rings, fast, slow.
Experiment:
Which Paper absorbs best:
Questioning:
You are going to be investigating –
What do you want to find out? (which paper absorbs the best)
What will you change? (the paper)
What will you keep the same? (size of piece of paper, amount of water, time)
Materials absorb water through capillary action. This means that water is attracted to the surface of the fibres and is drawn up into the spaces between them. The coarser the fibres the more easily the material absorbs water because there are more air spaces for the water to go into.
Give the children 3 different kinds of paper and ask them to investigate scientifically which is the most absorbent. Show them what equipment is available to do it.
Encourage the children to think of various ways in which this could be done with the available equipment. They need to design and make a support for their fair test. Then they need to see which paper absorbs the best.
Hang the three pieces of paper from the ‘crossbar’ or the string using blu-tack or plasticine. Put water into the butter carton (and a few drops of food colouring, which helps to show up the water) and hang the three pieces of paper so that they are just dipping into the water. Watch what happens.
Display against the light for the best effect
Reflection and observation:
What do you see?
What does this tell you about absorbing?
