Video: Thermal Energy

Bluebirds have been investigating how thermal heat moves between objects. First, the children predicted what would happen to the spirals when they were placed over the heat and then tested the experiment. Next, the children felt two tiles (one made of aluminium and one made of MDF), and predicted which one would melt an ice cube quicker.

Most of the children thought that the MDF tile would melt the ice quicker because it felt warmer to the touch. Mrs Parry told the children that both tiles were actually the same temperature. The children discussed metal being a good conductor.

Energy!

Bluebirds have been learning about energy (the ability to do work) and have discovered that energy comes in lots of different ways and cannot be created or destroyed. Kezi helped Mrs Parry to perform a class demonstration of Galileo’s rolling ball, with a long track and ball bearing. The class discussed which types of energy was used and also consided where energy was wasted which slowed the ball down (kinetic, thermal and sound). Each child, had great fun experimenting with a springy toy and there was lots of discussion around potential and movement energy.
Today, the class devised experiments involving pendulums which uses potential and kinetic energy.

Plant experiment

Bluebirds were eager to investigate how water travels through plants so set up experiments with lilies, celery and lots of food colouring! They examined the plants after 10 minutes, 2 1/2 hours and then 17 hours later. There were gasps of delight and amazement the next morning as children arrived into class! Children learnt that the xylem (similar to a tube, like a straw) takes water around plants. Look at our fantastic photos!

Curiosity – Stone Age

Bluebirds have been displaying the learning behaviour of curiosity recently. In their own time, these girls have all been researching our Stone Age topic…. just because they want to and are eager to find out more for themselves. Sophie found out about Stonehenge and has spent hours recreating it as a model. Melissa has produced some Great drawings with facts. Niah found out lots of extra facts and information.

Sorting leaves in criteria

Bluebirds continued with their leaf investigations this week and discussed their characteristics. Each group had a sample of leaves and sorted them using different criteria. The children sorted them according to length, size, shape, texture and colour. Afterwards, the children measured lots of holly leaves….which was very tricky! Lots of perseverance and team work was required! Children also had to think about how to use a ruler accurately!

  • Bluebirds found out the range of lengths of the holly leaves was 2 – 9 cms.
  • The most common length of the leaves was 6-7 cms.
  • The range of spikes on the edge of the holly leaves was 14 – 24.
  • The most common number of spikes per leaf was 17.

We decided the bigger the leaf the more spikes it has. We noticed this was similar when comparing oak leaves and the nodes around the edge of each.

Examining leaves under microscopes

Bluebirds shared what they already knew about plants today, before beginning their science topic of photosynthesis.

They watched an exciting video of a Venus Fly Trap in action and examined leaves under microscopes. Later they made observational drawings of a variety of leaves.

Please take a look at our amazing photos of the magnified.

Learning about reflection

In Science we are learning about light. Today we learnt that a reflection is when lights bounces of a reflective surface. A reflective surface has to be smooth, flat and shiny.

We played a game where we had to walk backwards through the hall. Other children were stood in the way as obstacles so we had to use a mirror to look behind us.
