5th Class Visit to Balbriggan Community College

The 5th class children from St Molaga’s were invited to visit Balbriggan Community College. The children were split into different coloured groups on arrival. They then, with their group leader, visited the art room to make gory cuts out of paint, glue and plaster, the tech room to look at robots, the science lab to make fire and dissect a lambs heart and finally to their new amazing gymnasium to jump the high jump and climb the climbing wall.

The children got a real flavour of what secondary school in Balbriggan Community College will be like if they chose to go there.

 

Sound

We carried our some fun expeirments today to learn about sound!

We used tuning forks dipped into water to show that sound causes vibrations!

We used elastic bands to create mini string instruments!

We used straws to make mini wind instruments!

Finally we made a ‘string telphone’ to test whether sound would travel along a piece of string! It did.

We made lots of of noise! (Click on the link to see more pictures.)

 

Electrical Circuits

We had great fun investigating electricity and how electrical circuits are formed!

We used insulators and conductors to make working torches and fans. We investigated how conductors can attach positive and negatively charged wires together to create and electrical circuit! The conductors attached wires together and sent electricity to different areas on the circuit. The wires were protected by plastic insulators.

It was so exciting to watch the light-bulbs light up and the fans begin turning when the circuit was complete!

Science- testing the strength of Materials: paper

OUR NEWSPAPER BRIDGE
In December 2016 we did a science project to test the strength of paper. We had to make a bridge of newspaper and see how many copies it would support. We separated the tables, leaving a gap wider than a copy. Then we placed a sheet of newspaper across the gap, to keep the paper in place we put baskets on each end for support. Then we started putting the copies on but we got around 50. Then we thought about folding the newspaper in half and putting on tape instead of baskets. It made it stronger and we got 77.

Experimenting with materials

We learned about different kinds of materials and their properties. We carried out an experiment to test some materials. We tested a tennis ball, a sponge ball, a ball made from plasticine and a ball made from rubber to see which one would bounce the highest. We wrote out the experiment and carried it out three times to make sure that it was a fair test. We discovered that the tennis ball was the bounciest ball.

Science Week in Third Class

We have been having great fun taking part in different activities during Science Week. We talked about what a scientist does. We learned about the work of some famous scientists, including Marie Curie, Galileo Galilei, Isaac Newton, Charles Darwin and Stephen Hawking. We created our own potions and wrote about them. We learned all about sound and completed different experiments to investigate it further. We made ear trumpets, panpipes, speakers, ear defenders and even tried to make rice dance! We worked in groups to complete the experiments and write about what we did.
