Science- Magic Pencils

Magic Pencils

Plastics are a polymer, which just means they are made of many of the same molecules stuck together in a long chain. When you pierce the bag with the pencils, it breaks the chain, but the end molecules of the polymer chain are sticky, and make a seal around the pencil that won't let water out.

Science- Musical Jars

Musical Jars 

Sound is a disturbance that travels through a medium as a wave. In this experiment, tapping on the jars with the spoon disturbs the particles of the jar causing them to vibrate. The vibrations in the jar are transferred to the air surrounding the jar, creating a sound wave. When the jars are all empty, the vibrations and the sounds are all the same. Adding different amounts of water to the jars causes the vibrations (and sound) to change.

You can change the pitch of the sound produced by the amount of water you put in the glass. Pitch is how high or low sound seems to a person and it depends on the frequency of the sound wave. When you add more water to the glass, the pitch is low. This is because the high volume of water in the glass makes it more difficult for the glass particles to vibrate, so the vibrations of the glass are slower and they have a lower frequency. When you add less water to the glass, the pitch is high. This is because the low volume of water in the glass allows the glass particle to vibrate more easily, so the vibrations of the glass are faster and have a higher frequency.

Science- Balancing Clowns

Balancing Clowns

The balancing clowns look at gravity and show how lowering the centre of gravity improves balance.

All objects have a balancing point, called the centre of gravity. The lower you make the centre of gravity the more stable the object is.

Science- Paper Helicopters

Paper Helicopters

We learned about Forces. In this activity we explored how some things fall and how varying the size of the rotor blades, the shape of the rotor blades and the weight of a paper helicopter affect the way a helicopter spins.

Active Schools Week

Active Schools Week

During Active schools week we had lots of fun and exercise. We stopped our work and music came over the speakers and the whole school dropped what they were at to dance. We did laps most days. Here are some pictures of us out doing our laps.

Sports Day- Piggy backs

Piggy Backs

Sports Day was such a busy day that we did our piggy back race the next day and had the most amazing fun!
