Today, Bluebirds learnt that muscles move our bones. They looked at a great representation using tubes and balloons to understand how our muscles work in pairs. Kai showed us his muscle definition!

Aftewards, we planned an experiment to answer the question “Do people with longer legs jump further.” We created a table ready to collect our data on but have been unable to get outside to conduct the experiment …. due to continual rainfall!

Super Skeletons!

In table groups, Bluebirds tried to draw a human skeleton and label any bones they knew. Lots of children located the skull, spine, ribs and funny bone! We compared each drawing before learning the real biological names. We discovered the skeleton is like a frame to hold our bodies up and also protects our vital organs. Next, we are going to make our own moveable skeletons.

Making Burglar Alarms!

Bluebirds, had a special visitor in Science today, who explained how the fire and burglar alarms work in school. We talked about circuits and linked our previous learning of electricity Mr Evans made a circuit for us and talked about conductors and insulators. We predicted whether items such as a paper clip, peg, staples, magnet, scissors, ruler and a paintbrush would act as a conductor and create a circuit, thus setting the buzzer alarm off. We recorded our results.

Understanding electrical circuits

Today, Bluebirds took advantage of the sunshine and stood out on the playground to create a circuit together! Esmay was the battery, Jani was the buzzer and everyone else were electrons. We walked around holding hands to make a circuit (moving like electricity would). Jani had to look out for an adult letting go and making a break in the circuit which would stop the buzzer working.

Back in the classroom, the children consolidated their knowledge linking back to when they made circuits, to play at a buzzer game. It was great fun!

Video: Charging Balloons!

Today, Bluebirds learnt about positive and negative charges with electrons. It was very exciting as the class used balloons to collect confetti. Afterwards, the children used the balloons to make plastic rings levitate and float in the air. We felt like we were doing a magic trick!

We considered how we could collect data such as timing how long do we rub balloon with hair/wool cloth for or how m at times do we rub, how long we could keep the ring floating for, how many rings can you levitate at once and how much confetti pieces could be collected.

Video: An electrifying experience!

Bluebirds began their new topic of electricity today. Miss Timerick asked the class to think of as many things as they could they needed electricity. They thought of lots of household items and technology that needed it but forgot about things which needed batteries!

They watched a demonstration with a Van de Graaff generator. When the belt was wound up it made Mrs Johnson’s hair stand up! After, they saw metal tins blow off the top of the generator little foil balls jump around in a tube.

We talked about static electricity and energy. We learnt the metal rubbing against the belt created electricity in the metal dome. The force of the friction causes electrons transfer from one material to another. The material that has gained electrons becomes negatively charged whilst the other has become positively charged because it has lost electrons. The sparks occur when electrons move to balance the difference in charge on the atoms in the material and become neutrally charged once more.

If two objects with the same charge are brought close together they repel. This is the reason for hair standing up as the individual charged strands of hair are repelled away from the head and each other. Similarly, opposite charges attract each other and this can be seen when you rub a balloon on your hair and then bring the balloon close to your hair and the hair lifts towards the balloon.
