We Can Code!

 

As part of our Space topic, we have been learning to code using Crumbles. Our lessons have included learning on algorithms, condition, selection, ‘do until’ loops, ‘forever’ loops and debugging. 

In our final few lessons, we had the opportunity to put all of our learning into practice. In groups, we designed a model of a space rover. This included designing the model itself as well as working out how the Crumble would be connected to its components. We also wrote out an algorithm using selection so we knew what we wanted our rover to be able to do. Our next step was to construct our models using a variety of materials including cardboard, egg boxes, kitchen rolls and even pencils! We also had to work out how to attach our Crumbles components.

Next, we implemented our algorithms as code, making sure we included selection and a ‘forever’ loop. Our brief was to include at least two output devices. We all chose to use two motors and a sparkle (light) as well.  We then ran our programs to identify any bugs, returning to the code or algorithm to debug it where necessary. Some of us also needed to modify our models at this stage to ensure they met the requirements of the task and worked as intended. We think our rovers look fantastic and are really proud of ourselves and our coding abilities. What do you think?

 

Space Centre Trip!

 

Wow! What a super day Class 4 had last week. We took a trip to the National Space Centre in Leicester. This trip linked really well with our Space topic and, as an added bonus, took place during British Science Week! It was also great to have time to get to know some children from Denton and to make new friends.

Our day started with a tour of the night sky at the UK’s largest planetarium. It was amazing to see what the Earth looks like from space and to get up close to the International Space Station as well as planet Mars! The children all agreed that this experience really furthered their knowledge of our solar system and galaxy.

After this, we had time to explore the six galleries – all of which were very hands-on and interactive. We also climbed the 144 steps necessary to reach the top of the 42m high Rocket Tower!

We all took part in a ‘Life in Space’ interactive workshop. We were able to conduct experiments which furthered our understanding of how astronauts survive in the harsh environment of space. In particular, we explored why each of the different layers of a space suit are necessary to protect the astronaut and how they perform when astronauts are carrying out a spacewalk. We worked out why losing pressure in a space suit was life-threatening and thought about the hazards represented by micrometeorites.
