The Great Egg Drop Challenge

As part of Science Week the children in the Junior Room participated in the Great Egg Drop Challenge. The difference work groups were each given an egg and a range of materials – with the challenge to use the available materials to ensure that the egg could be dropped from a height without breaking. This challenge encourages problem solving, egg -perimenting and egg-samples of  egg- cellent,  egg- quisite and egg-traordinary egg puns (sorry!)

Mr. D’s Workshop – Rubber band powered car

When you stretch a rubber band it stores potential energy. Specifically it stores elastic potential energy—the type of energy stored when a material is deformed.  A rubber band can be attached to a simple machine—a wheel and axle—to build a simple rubber band–powered car. Experimentation and re-design allows the rubber band – powered car to go further and faster. During Mr. D’s Science Workshop the children explored and experimented with rubber band-powered cars to make their cars go further and faster. Hope you enjoy our video.

3D Printing

During the summer two teachers from Togher N.S. were invited to a workshop on 3D design and printing. This 3.5 day course was funded by EIT-Manufacturing and supported by Stryker and I-Form (University College Dublin) in Ireland; Arts et Metier Institute of Technology in France; and University of Tartu in Estonia. Participating teachers were provided with a free, long-term loan of a 3D printer for their school.

3D printing makes learning active, giving students hand-on experience and brings their CAD (Computer-aided design) projects to life. With the expansion of the applications of 3D printing technology throughout industry, it is important that students start to develop the design and technical skills required to harness this technology while giving them an enjoyable, self- directed experience.

This week we explored computer aided design and set up our 3D printer. We soon printed our first CAD drawings.

 

The science of bridge building

The children in the Senior Room have been studying the science of bridge building. They were given the challenge of designing and building a simple bridge using paper, glue and some sticky tape. The finished bridges were then tested using plastic cubes.

Downhill Car Race

The children explored Gravitational Potential Energy during Chuck Delpier’s Science Workshop. The children were delighted to learn that this involved designing, refining and improving downhill race cars to travel faster, straighter, further and smoother.

Compressed Air Water Rocket

Chuck Delpier’s Science Workshops really allow the children to explore science in a “Hands On – Minds On” manner. During the recent workshop the children learned about Newton’s third law – To every action there is always opposed an equal reaction. All rocket engines operate on the principal of this law so it was time to go outside and launch some rockets! We hope you enjoy our video below.

Friction and Heat

During Chuck Delpier’s (Mr. D.) Science Workshop the children explored the science of Friction and Heat. Friction is the resistance of motion when one object rubs against another. Anytime two objects rub against each other, they cause friction. Friction works against the motion and acts in the opposite direction.When one object is sliding on another it starts to slow down due to friction. This means it loses energy. However, the energy doesn’t disappear. It changes from moving energy (also call kinetic energy) to heat energy. This is why we rub our hands together when it’s cold. By rubbing them together we generate friction and, therefore, heat.

During the workshop Mr. D introduced the children to pump drills. A pump drill is an ancient tool traditionally used to generate friction heat for starting fires, as well as for boring holes. A pump drill generates friction and heat through rotational momentum which is built and maintained by repeated twisting and untwisting of a cord.
