The foot
Hi in this post i am talking about the foot.The foot is a term used to measure length it is a non SI unit .A foot equals to 30.48cm.I think the foot is not suitable to measure length as it can only be used to measure objects that are large in size but not the smaller ones and so it may be inaccurate when measuring the shorter objects.
The enemies of Bees
Hi in this post I am going to talk about the enemies of bees.
Firstly we have the Honey Bee they steal the honey of the bees.
Secondly we have the Death's Head Hawk Moththis moth flies into bee hives in the dark at night and lick their honey with its long tongue.
Thirdly we have the Blister Beetle Grub it ambushes bees when they are picking pollen in a flower and hitches a free ride back to their hive where they will hide in their cells and eat the grubs of the bees.
Fourth the mouse is another animal who steals honey but their bodies are hard to move so the bees cover them with gum from trees and also to stop them from stinking
Fiftth is the Humans they want their honey to eat and bee's wax to make candles
Lastly is the Cuckoo Bee they look like bees but once they are inside they will lay their eggs in the hive

Some facts about the Doppler effect
Hi in this post I will be talking about the Doppler effect that was discovered by an Austrian scientist named Christian Doppler.Doppler thoght that a moving sound always changes pitch in the same way which is the Doppler effect.When the sound waves comes towards a person they are squashed together.So one will hear the sound in quick succession at a high frequency.As the sound moves away one hears it at alower frequency because the sound waves are more widely spread.This was tested by a sccientist by putting a band of buglers to play on a moving train and have the train to drive past him.
