In Room 12 we have been experimenting with different types of slime recipes. Slime is a very interesting substance. Here is the science behind the slime!
Polymer: ‘’poly’’ means many parts.
A polymer is a long chain of molecules that gives the substance the ability to stretch and be very flexible.
Our Recipe: Glue is a liquid polymer. The tiny molecules in the glue are in strands like a chain. When the Airwick and washing powder are added the strands in the polymer glue hold together, giving it its slimy feel. The Airwick and the washing powder link all the polymer strands together.
Solids, liquids and Gasses:
We normally describe something as a solid, liquid or gas. Slime is unusual because it behaves as a solid and a liquid. It can be thrown from hand to hand as a solid and when put into a container it will fill the four corners like a liquid. This is called oobleck slime.
The recipe below was our most successful recipe.
- Pour PVA glue into a bowl.
- Squirt shaving foam into the bowl with the glue and mix.
- When mixed pour a capful of food colouring into the shaving foam and glue mixture.
- Mix until all combined.
- When the mixture is all combined add some Airwick and stir.
- When stirred add some washing powder and warm water and stir well.
- If it is too watery add washing powder and water.
- When combined pick it up out of the container and kneed for 10-15 mins.
- After 10-mins put in a container and leave in the fridge.
We have had great fun exploring the properties and characteristics of materials over the past few weeks. This work all led up to our school’s annual Science Fair. Last Thursday, during the fair, we got to show off our experiments to the whole school. We also had many parents who came to see our wonderful work.
One experiment was about tracing – we found out that some materials are good for tracing (transparent) but others are not (opaque).
The other experiment was all about absorbency – we devised a fair test to discover what materials would be best to mop up a spill of water on our desks. It turned out that tissue, newspaper, sponge, and cloth were good at soaking up liquids. Tinfoil and plastic, however, were not very useful to us!
We had great fun in Junior Infants for Science Week. We were learning about forces and the different ways we can make sound.
A force is something that makes something move. We were learning all about pushing and pulling. We also learned about ramps. We had little cars and we were experimenting with them to see how we could make them move the fastest.
We also were learning about Sound. We filled bottles with water so that each bottle had a different amount of water in it. Each bottle made a different sound. We learned how to play Twinkle Twinkle by hitting the bottles.
Last Friday, 24th November some parents and pupils from junior infants to 2nd class took part in a play workshop in our school hall. The workshop aims to promote active play between children and their parents.
Thanks to all the parents who came in and especially Sligo Sport and Recreation Partnership who came into run the workshop.
The children really enjoyed the afternoon.
In room 1, 4th and 5th class worked together on a collaborative art display. We each took a quarter of a circle shape and first sketched a design on it, then painted it, on our own. Each one of them on their own is quite small an interesting, but when we put them together, they certainly make a pretty picture. Just like us when we work together as a team!
Today, we had our annual Science Fair at school. Second class have been learning about light and shadows.
We learned that light reflects off different materials for example, a mirror or a glass prism.
We also learned how shadows are made when light cannot pass through an opaque object.
The children also performed a shadow puppet show!
Come along to the Showgrounds on Saturday 18th of November at 5pm for a Charity Fundraiser in memory of Paddy McLoughlin. Proceeds go to Croí. Plenty of fun activities planned for children at the event in the Showgrounds.
Saturday 18th of November
This week in second class, we have been talking about the RSA’s ‘Be Safe, Be Seen’ campaign. We discussed how the evenings and mornings are darker now that it is Winter. Children know how important it is to keep active during the Winter but that we also need to keep safe. Each child received a high-visibility arm band so that they can wear it if they are walking to school, playing outside or if they are outside on their bikes.
Here we are wearing our high-visibility armbands:
