Living Things Plandaí
Rang a 4C, by growing seeds indoors, explored the factors that affect plant growth such as water, light and heat . The seeds were planted in January and
included spinach, cress and peas. They have recently been planted in the school
During this process, the class also investigated how plants
transport water from their roots to their leaves using capillary action.
A plant has four central pieces.
RootsStemLeavesBlossomThe roots drink water from the soil.The water travels through the stem.The leaves light from the sun to receive energy.The blossom helps spread pollen so other flowers can bloom.
What you need to complete the experiment.
CeleryFood ColoringA CupWaterAdd 1/2 a cup of water to your cup.Add a drop of food coloring to your cup.Place the celery in the cup.Leave over night so the plant can do its magic.Cut half way through the middle of the celery and see if your celery has changed.Check your celery every night to look for a change.
An féidir leitreachas a ghinúint ó a bheith ag rothaíocht?
Réamhrá Is í an cheist atá faoi iniúchadh againn sa tionscanamh seo ná ‘An féidir leictreachas a ghinúint ó bheith ag rothaíocht?’ The question we are examining in this project is ‘Can electricity be generated from cycling?’ Hipitéis- Nuair a thosaíonn rothaí ag rothaíocht, cruthaítear fuinneamh cinéiteach nuair a bhruann an rothaí síos ar an troitheán. Athraítear an fuinneamh cinéiteach go dtí fuinneamh meicniúil agus tosaíonn an roth ag casadh. Má chuirtear dynamo ar an roth deiridh, athraítear roinnt den fuinneamh meicniúil isteach i fuinneamh leictreach. Hypothesis- As a cyclist begins to cycle; kinetic energy is produced as the cyclist applies force on the pedal. This kinetic energy is converted to mechanical energy and the back wheel begins to turn. By placing a generator (a dynamo) onto the back wheel, some of this mechanical energy can be converted into electrical energy. Tuar-Má chuirimid dynamo ar an roth deiridh, is fé…
This activity involved the design and creation of a sweet machine.Each group received two large cardboard cylinders, one small cardboard cylinder, one metre of lagging pipe, cello tape and a cooking cone to aid in the design of their sweet machine. We were presented with the task of designing a sweet machine using all of the above mentioned materials with the objective of sending a gobstopper (marble) from the top of the machine to the bottom and land in a cup.
Múinteoir Cian led an exploration and discussion on the physics of a roller-coaster. We talked about the the scientific principles that underpin the functioning of roller-coasters such as gravity, friction, speed, velocity, potential energy and kinetic energy.
Within our groups we drew and designed our sweet machine. When we were satisfied with our design we began to experiment with the materials and began to build our sweet machine.
