We investigated using different amounts of Alka-Seltzer tablet and vinegar and timed how long it took for each rocket to blast off using stopwatches. We found out that when bicarbonate of soda (in the Alka-Seltzer) is mixed with vinegar, a new material is formed and a gas is produced (carbon dioxide) which creates bubbles that force the lid off the film canister.

Pupils revisited their understanding of how electrical circuits work.
cut off toothbrush head
coin cell battery
vibrating motor
double-sided tape
electrical tape
pipe cleaners
googly eyes
light emitting diodes
Pupils used their creativity and a fair amount of dexterity and perseverance to make their brushbots work.
We used this activity from the British Science Week Primary Activity Pack to investigate how much cargo a ship could carry without sinking. We investigated the effects of distributing the load in different ways.
We reviewed the way animals are classified; discussed how shadows are formed; made shadow puppets of animals and created backgrounds to put on a shadow puppet show at home.
We used the Royal Institution's Experimental lesson Rufus and the Racers to explore the way soap affects how water molecules hold on to each other. Information about the activity was downloaded and sent home to parents.

Pupils investigated what effect dipping their finger in differerent substances had on the surface tension of water.
When they dipped their finger in dish washing liquid, the dried herbs moved quickly to the edge of the plate.
They investigated a variety of substances.
They came up with their own rating system and recorded their results. Pupils raced soap racers.
We used the Royal Institution's Experimental lesson Memory Masters to explore ways to improve memory.
Pupils found it difficult to memorise 10 items just by looking at them for 30 seconds.
Pupils thought of different ways to help them remember the items e.g. writing them down or drawing them.
They were shown how to link items in a story to help them remember. Some pupils did this verbally.
Some pupils chose to draw their story
Some pupils chose to write their story.
They were able to remember more of this items by doing this.
The accompanying information sheet was sent home to parents. https://www.rigb.org/docs/memory_masters_infosheet_0.pdf
Making use of the British Science Week Primary Activity pack, we investigated camouflaged creatures - tigers, stick insects, chameleons and snakes.We discussed ways that animals camouflage themselves and why they do so.
Pupils took turns hiding items around the lab in places where they would be camouflaged whilst everyone covered their eyes.
Pupils took turns finding them. We said 'Hotter and Colder' to help them.
Pupils cut out butterfly shapes.
Pupils coloured them so they would be camouflaged in a particular garden scene.
Pupils investigated the best shapes to support a mass using dried pasta and plasticine.
Pupils have been practising tricks from the book Cool Science Tricks - 50 Fantastic Feats for Kids of all Ages by Daniel Tatarsky.
Exploring the release of restrained energy
Exploring potential energy
Exploring light travelling along the path of least resistance
Exploring loose strings of molecules - polymers
Exploring centre of gravity
Exploring water evaporating and cooling over and over again
Exploring gravity, upthrust and measuring distances.
Pupils shared ideas about whether the lighter or heavier object would hit the ground first.
They discovered that mass made no difference.
Would surface area make a difference?
Yes!
Pupils investigated materials that act has insulators, tested these, measured temperatures and designed coats. This activity was from the British Science Week Primary Activity Pack.
choosing insulating materials
using more than one layer of material
reading temperatures
coat design
