Year 4 had great fun making our own lava lamps. We learnt that the chemical reaction in the oil mixture produced
carbon dioxide. Gas is lighter than water, so the air bubbles floated to the top bringing coloured water with them,
which created the lava lamp effect!
We also created ‘Scribble bots!’ We made and attached a simple circuit to the top of an empty Pringle pot. Then, we
taped three felt-tip pens, evenly spaced, to the outside of the pot and attached a cork to the motor for momentum.
Once the circuit was complete, we let the Scribble bot loose on paper!
We were great computer programmers this week also. We created flashing hearts, our names and pictures by
programming the Microbits using blocks of code on the MakeCode website. Earlier in the week, fantastic mazes were
designed and created for our Dash robots to navigate. We had to debug our code in order to escape the maze.
In Maths, we made some creative tangram puzzle pictures and solved problems as a team in a fun workshop with The
Problem Solving Company.
A big thank you to the parents who kindly came to talk to us about their careers in STEM. You really inspired us.
