Term 2 Week 10 - We all work together to build one big marble-run, Our Egg-Speriments show you can dissolve the shell of an egg with vinegar, Zico comes in for another visit.

 Each student took turns to glue-gun a piece onto the marble-run...the tricky bit was continuing on from the last person so that the marble kept rolling smoothly.

 Zico comes in for a visit during a wet lunch.

The homework shows that an egg-shell is no match 

for the acid in vinegar!
