While we are at it, we will give a free class to your friend too!
COOKING UP SCIENCE
Heat is such an integral part of cooking that you’d be hard-pressed to think of a culinary example where there was no heat involved. Not only does it make food easier to digest, but it also opens up a whole new world of flavours, aromas, colours, and textures. This week, we will turn up the heat as we transform sugar into caramel and then use the Maillard Reaction and a few amino acids to toast up the perfect grilled cheese sandwich. Finally, we will use heat and other chemicals to denature proteins and “poach” some eggs to go with it.
PLANET EARTH, ANIMATED
As lava cooled, these new lands shook under the barrage of asteroid impacts that plagued our young planet. Nowadays, the Earth mostly shudders for another reason (a reason we will explore next week), and it is these more modern earthquakes that have allowed scientists to peer right down to the core of our planet. However, before we delve any deeper, we should ensure our homes can withstand the next seismic shift. Using nothing but sticks and marshmallows, our would-be engineers will have to construct a tower that reaches for the sky while we shake the ground beneath it with our drill-powered earthquake simulator!
RAMPANT REACTIONS
Now that we can tell our acids and bases apart, it’s time to neutralise them. Mixing one with the other produces a salt, water, and a more neutral solution - handy if you have a spot of heartburn and even handier if you need to measure the concentration of an acid or base. After running a few tests to select the right indicator, our chemists will turn detective! They will perform a titration - a carefully carried out neutralisation with an acid of known strength - and find out the strengths of some mystery bases.
