Yesterday afternoon I dragged my friend to Denge Wood forest. While there, I spotted one of my top five favorite beetles. These lustrous and magnificent little guys are green tiger beetles (Cicindela campestris).
They are incredibly fast predatory beatles that hunt down and eat other insects. The larvae of this beetle live in individual burrows in sandy soil. They flick out the sand around them creating a pitfall that other insects fall into.
So beautiful but deadly.
I went fossil hunting down at the Warren (in Folkestone, Kent, UK) on Thursday last week. These are some of my favourite finds from the trip (I washed them up at home).
Fossil hunting is great fun. If you live in the UK, and fancy giving it a shot, then there are some really handy websites that you should check out. https://ukfossils.co.uk/ and http://www.discoveringfossils.co.uk/fossil-locations-of-great-britain/
If you don't live in the UK but still want to give it a go then I would recommend looking for local fossil hunting clubs, societies and websites. Failing that you should try to look for areas where sedimentary rocks are being eroded. For instance, cliffs by the sea, rivers, old quarries, etc.
Just make sure you don't trespass or go anywhere too dangerous. For instance, if you are fossil hunting under cliffs at the beach, don't get to close to the cliffs (falling debris and cliffs collapsing) and plan around the tides (you don't want to get cut off).

Metallic Bonding
A short one to finish off my first ever mini-series on bonding – ionic, covalent and finally metallic. There are metallic and metallic compounds and elements but for the A Level exam, we must look at the bonding within metals themselves. Don’t worry – I saved the easiest to last!
Metals are most usually solid so have particles packed close together. These are in layers which mean that the outer electrons can move between them rather than being bound to particular atoms. These are referred to as delocalised electrons because of this.
It’s pretty common knowledge that metals are good conductors of heat and electricity and it’s these delocalised electrons that give them this property.
Metals are therefore without their electrons so become positive ions. The metallic bond is actually the attraction between delocalised electrons and positive metal ions in the lattice. And that’s pretty much metallic bonding, you just need to know the properties of metals which are touched upon at lower levels of education.
These are the properties of metals:
1. High melting points
Metals have large regular structures with strong forces between the oppositely charged positive ions and negative electrons, meaning these must be overcome to melt the metal – this requires a large amount of heat energy. Transition metals tend to have higher melting points than the main group metals because they have large numbers of d-shell electrons which can become delocalised creating a stronger metallic bond. Melting points across a period increase because they can have progressively more delocalised electrons: Na+, Mg 2+ and Al 3+ for example.
2. Heat conductivity
Heat is conducted if particles can move and knock against each other to pass it on. Delocalised electrons allow this to happen. Silver is a particularly good conductor of heat.
3. Electrical conductivity
Delocalised electrons can carry charge and move, the two requirements of electrical conductivity. Current can flow because of these delocalised electrons.
4. Ductile and malleable
Metals can be stretched and hammered into shape, making them ideal for things such as wires. Layered lattices mean that layers can slide over each other without disrupting the bonding – it is all still held together by the delocalised electrons and their strong attraction to the positive metal ions.
5. High densities
Being a solid, metal ions are packed closely together so they have a high density, which makes them ideal for musical instrument strings. These can withstand the frequency of vibration whilst also being thinner.
