Science week experiments –
Red Nose Day Lava LampsÂ
We gathered together our resources and disussed what we thought might happen when we mixed oil and water togther. We then followed the experiment to create our own lava lamps.
How it Works:
The oil floats on top of the water because it is less dense or lighter than water. The food coloring has the same density as the water so it sink through the oil and mixes with the water. When you add the tablet it sinks to the bottom then starts to dissolve. As it dissolves it makes gas, carbon dioxide. Gas or air, is lighter than water so it floats to the top. The air bubbles bring some colored water with them to the top. When the air comes out of the colored water blob, the water gets heavy again and sinks. It does this over and over again until the tablet is completely dissolved.
Today we excited to discover some new exciting Robots had arrived for us to borrow.
!
We used our coding skills to program them to move forwards, backwards, dance and even make lots of silly noises.
We also used our class Dash robots and have learned how to make Dash move quickly all around the classroom without crashing into any of the desks!
We even programmed our bee bots to reverse park!
We are getting ready to take part in the Glasgow Science Festival Creating Engineers Challenge next week.
We sorted our Knex and worked together to organise the different parts into our storage boxes. We loved this challenge and showed fantastic collaborative skills to tidy up our resources. Mrs Ross was very impressed!
We then had a go at making some of our own designs to practise building with Knex.
Next step : work in teams to plan, design and build a structure from our chosen theme.
Next week we will take part in a times team event. Watch this space to see our COP26 inspired designs.IMG_6729
