Yr10s. Frequency is measured in hertz. The higher the frequency the shorter the wavelength. Gamma rays have the highest frequency.

[TCA Science @TCAScience]

Yr 11s. Your exams are next week. Don't underestimate how much revision you can do. Ionic compounds conduct electricity when molten.

[TCA Science @TCAScience]

Yr11s. Half life is the time it takes for a radioactive nucleus to decay by half.

[TCA Science @TCAScience]

Yr10s. The red shift provides evidence that the universe is expanding.

[TCA Science @TCAScience]

Yr 10s. A chemical diffuses across a synapse(the gap between 2 neurones)

[TCA Science @TCAScience]

Thanks to the yr 10s for turning up for revision. It wasn't that bad was it?

[TCA Science @TCAScience]

@jessanneXO Get cracking. It will all be worth it in the end.

[TCA Science @TCAScience]

Yr 10s. Alkanes have single bonds and are saturated. Alkenes have a double bond and are unsaturated.

[TCA Science @TCAScience]

Yr 11s. Stopping distance=Thinking distance + braking distance.

[TCA Science @TCAScience]

Yr 10s and 11s. Protons are positive with a mass of 1. Neutrons are neutral with a mass of 1. Electrons are negative with a mass of 1/1850.

Yr 11s graphite is a giant covalent structure made up of layers that can slide over each other. The free electron means it conducts electric

[TCA Science @TCAScience]

Yr10s. Cracking is breaking up a large hydrocarbon into smaller hydrocarbons.
