Speed Test.

In science we have been learning about how to  calculate speed from dividing distance and time. We used this to investigate the speed of cars on Carmen Road .We measure the road up to 50 meters with measuring tape and we timed the speed of each car went from one light post to the other light post. Furthermore, we had to find the speed of the 10 cars. We divided distance by time to find the speed. After we find the speed we saw three out of ten cars over speed the limit from the traffic light. We came back to class and added up all the times of the car and divide it by ten to find the average time.

Digestive system part 
functions:
Salivary glands - The salivary glands produce saliva, which keeps the mouth and other parts of the digestive system moist.

oesophagus - The oesophagus is a long, thin, and muscular tube that connects the pharynx (throat) to the stomach. as the conduit for food and liquids that have been swallowed into the pharynx to reach the stomach.

liver - The liver's main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. 

stomach - The stomach secretes acid and enzymes that digest food. 

Pancreas - The pancreas also produces the hormone insulin and secretes it into the bloodstream, where it regulates the body's glucose or sugar level .

Small intestine - is absorption of nutrients and minerals from food.

anus- he anus is surrounded by sphincter muscles that are important in allowing control of stool.

rectum-The rectum acts as a temporary storage site for feces.

appendix-appendix is unknown.

large intestine- is to absorb water from the remnants of indigestible food matter.

Duodenum- it receives partially digested food known as 'chymes' from the stomach.

Bile Duct- is to carry bile from the gall bladder and empty it into the upper part of the duodenum.

Gall bladder - is to store and concentrate bile.

Digestive System 

Human digestive system, the system used in the human body for the process of digestion. The digestive system is a set of organs, that work together to process complex food like starch into simple molecules your body needs.

Function 
The function of the digestive system is digestion and absorption. Digestion is the breakdown of food into small molecules, which are then absorbed into the body.
