The children enjoyed designing and constructing 3-D models of the sun, Earth and moon which helped them understand the relation between the orbiting bodies in space.
We loved our fun parachute egg drop experiment! This was a great demonstration of the forces acting on parachutes. If you drop something it falls to the ground. This is because it is pulled by the gravity of the Earth. We noticed that some eggs dropped faster than others, this is because of air resistance and how successful our parachute was!
Forces in action! Different types of surfaces create different amounts of friction. Some materials are much smoother than others. The children enjoyed investigating which materials created the most friction on a bicycle wheel! Placing something on a spinning wheel will cause friction to slow the wheel down; this is how brakes work.
Years 5 and 6 were learning about Materials and their properties. They enjoyed lots of practical activities and scientific enquiries to understand the differences between a variety of materials and how materials can be mixed and dissolved and reversibly and irreversibly changed.
The aim of this experiment was to completely separate each substance in the mixture – a mixture of iron filings, sand and sodium chloride (salt). The children first removed the majority of the iron by the magnet and then filtered the sand and salt mixture which left a salt-water solution. The children were excited to see the salt crystals which were in the bottom of the dish after the liquid had evaporated! The separation of each component of the mixture was not perfect but a success and a fantastic learning experience.
Here we observed some reversible and irreversible changes when materials were mixed together. Some produced an irreversible reaction and a new product called carbon dioxide.
The children explored what happened when a candle burned and recorded the reversible and irreversible changes that occurred and the materials that were produced.
