What are the 5 parts for? 
Link: Rovers 5 parts

Fill in the table below.

Name:	Purpose:
Wheels	The Mars Rover has six wheels and each of it has its own individual motor. The steering capability of the rover allows the rover to in spot, it turns a full 360 degrees. The four wheels steering also allows the rover to swerve and curve.
Solar Panel	The rover requires electrical power to operate if there's no power the rover would not operate. The rover carries a radioisotope system, this power produces electricity.
Laser	The super cam is located in the main head of the rover and it fires a laser at mineral targets that are beyond the reach of the rovers robotic arms.
Camera	There is a total of 23 cameras on the rover, 9 of the cameras are for engineering, 7 of the cameras are sciences cameras and 7 of them are landing, descending and entry cameras.
Shovel, rock pick,drill	These are called the sample handling, the rover will gather samples from the rocks and soil using its drill. The rover will then store the sample in tubes on the surface.

The Case of the BArefoot Burglar l Home Chemistry

The case of the Barefoot Burglar

In groups of 3, you are going to need to use your forensic knowledge to solve a crime. You must use the web page: Barefoot Burglar Evidence

1. Determine which of the four suspects is the "Barefooted Burglar"? 
2. What do you think was the motive for this crime? 
3. Write the results of your findings and convince a jury of your peers

The Crime

At approximately 7:15 a.m., Friday morning, Mrs King, the science teacher, thought something was fishy as she walked down the hall and noticed that her door was open. She walked into her classroom and immediately discovered that the small aquarium had been broken and her prized goldfish were gasping in the sink. Besides the broken aquarium were the shattered remains of the pink piggy bank that had been on the shelf above the aquarium. A can of blue paint was spilt on the floor. Footprints of a barefooted burglar led to an open window. Bits of a white powdery substance was found next to the broken, empty, piggy bank. The only other item found was a half-eaten large chunk of chocolate candy.

When the police arrived they immediately began to gather forensic evidence.

Dan the Man Height : 176 cm Alias: The General Dan was wearing a woollen general's uniform with small holes when apprehended in the woods. He claimed to be gnawing on wood for moisture and insects to practice his survival training. His teeth look like beavers from gnawing. His wife complains that she never has any baking soda due to Dan's compulsion about storing clothes in mothballs. He thinks the baking soda takes away the mothball smell, so he stuffs his pockets with the substance. Also, his wife reports that her giant chocolate kisses continually disappear from the candy cupboard. He blames their dog Patton, an English bull terrier, who patrols the neighbourhood. His neighbours report that Dan loves the military. He was very regimented about playing taps on his bugle every day at sunset until an irate neighbour broke his bugle. Dan has been trying to save money for a new one. Peg the Leg Height: 152 cm Alias: Lucky Lady

Peg is a librarian known for hanging horseshoes and four-leaf clovers in her library. Employees say she is so superstitious she insisted on carpeting in the library instead of laying tiles so she would not step on the cracks. She wraps construction zone tape around open ladders so no one can walk under them. Cola bottles litter her office, which she drinks with chocolate chunks. Her teeth are chipped from knocking the bottles against them. She is always throwing salt over her shoulder for good luck and keeps a salt shaker in her purse. Her alibi is that she was busy closing open umbrellas the morning of the crime.

Jake the Jock

                                                                         Height 201 cm

                                                     Alias: Armchair Quarterback

                                                                                         

Jake the Jock is known for quoting statistics on every sport from boomerang throwing to sledge dogging. His neighbours report that he is the neighbourhood pitcher for baseball games. Last year a baseball hit him in the mouth and knocked out his front tooth. This has cramped his eating style of chocolate chunks, candied apples, and corn on the cob. His wife claims that on the morning of the crime Jake was rubbing his hands with cornstarch to keep them dry in preparation for an important baseball game.

Lou Lou Height: 160 cm Alias: Sweet Tooth

Lou Lou is so addicted to sugar that she never leaves home without it. She loves to bake sweet things and has an entire pantry full of sugar bins. She claims to have been baking her famous chocolate chunk cookies the morning of the crime (although not a morsel of the cookie or chocolate chunk was left when the police arrived.) Lou Lou rarely wears shoes, which often causes her to slip and break things, especially her collection of ceramic pigs. Evidence:

• Fingerprints: Sticky, 'swirl' fingerprints were lifted from the aquarium and piggy bank. 
• Footprints: The painted footprints were measured and were for 26 cm feet. 
• Teeth: The chunk of chocolate candy was collected for examination. It appeared there were teeth imprints.
• White Powder: The white powdery substance by the piggy bank was carefully placed in a plastic bag and taken to the forensic chemist for identification. It had very small grains and when mixed with Iodine it reacted making the colour brown. It did not have a smell.

Name: Dave

                        

Fingerprints: No.

Mouth prints: Has a chipped tooth.
Shoe size: 16
White powder: None found.

Name	Evidence
Dan	Fingerprints: Whorl Mouthprints: Beaver looking Shoe size: Unknown White powder: Baking Soda
Peg	Fingerprints: Loop Mouthprints: Chipped Teeth Shoe size: Unknown White powder: Salt
Jake	Fingerprints: Whorl Mouthprints: Front tooth knocked Shoe size: Unknown White powder: Cornstarch
Lou	Fingerprints: Arch Mouthprints: None Shoe size: Unknown White powder: Sugar

Findings: ( what did you find. Summarise what you have written in the table above)
As we found out more evidence from each person we noticed that they don't have any shoe size. Dan the man had a whorl fingerprint, beaver looking teeth and he carries baking soda around. Peg the leg has a loop fingerprint, she has chipped teeth and carries salt around. Jake the Jock has a whorl fingerprint, his front tooth is knocked out and he put on cornstarch on his hand. Lou Lou has an arched fingerprint, no mouth prints and she is addicted to sugar making her carry it around. 

Verdict: ( who is the burglar and why)

I think that Dan the Man and Peg the leg are the barefoot burglar's because in the evidence found by the police the fingerprint is a whirl and the police also found out the white powder is soaked in water but if you put vinegar in it, it bubbles up. With peg, the police also found a note saying 'I'm Sorry', and Peg the Leg's writing is almost the same as it, 

Home Chemistry: The Feet can measure the height.

THE FEET CAN MEASURE THE HEIGHT

The bones of the feet can tell a lot about a person. What do feet reveal about a person's height? Forensic anthropologists team up with law enforcers to help solve crimes.

Bones of the feet can reveal an interesting fact about an individual. Let's combine math with forensics to see how.

Aim:  To use forensic science techniques to measure the height of a criminal.

Material:

1. Yourself  
2.  1m ruler 

Steps:

1. Get a 1m ruler. 
2.  Measure your height, on a wall.
3.  Measure your foot on the ground. 
4.  Record your measurement.
5.  

Findings:

Name	Foot  (cm)	Height (cm)
Maia	25.1cm	140cm
Lyan	24.9cm	143cm
Alliah	26.4cm	152.5cm

15 is the number used by investigators to determine a person height based on their feet. This is because 15% of a person height is the length of their foot.

Find out what percentage of your height is your feet. To do this you need to:
Divide the length of each person's foot by his/her height then multiply it by 100. 

15 is the number used by investigators to determine a person height based on their feet. This is because 15% of a person height is the length of their foot.

Maia - 17%

Lyan - 17%

Alliah - 17%

Conclusion 

This was a really fun experiment because I  got to learn how police solve crimes. I also learned how tall I am and my foot size. Another thing I learned was that they also use maths in forensics.
