Sound experiment

Aim: To test my hearing.

Hypothesis: That my hearing will be 18453HZ.

Method:

1. Listen to the sound test.
2. Record what my hearing level is.

Findings: My hearing was 18453HZ.

Conclusion: Most people in our class is about 18400 HZ low or up to 20000HZ.

Science Hurumanu/ What I would like to see in 2040

Today in science Huruma we are watching a movie called 2040 the character is Damon, and we are is going to answering two questions. 

First one: What are 2 things you learned? I learned lots of things, like the man Damon is travel to lots of countries, like New York USA, Bangladesh. Bangladesh is the first countries he went, at there I see peoples house roof, they all are using solar energy. The second thing is I learned to protect our word and plant more trees, make our word clean.

Second one: What I would like to see in 2040? I like to see the world is full of trees and more power.

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 spilled 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 woolen 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 a 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 neighborhood. His neighbors report that Dan loves the military. He was very regimented about playing taps on his bugle every day at sunset until an irate neighbor 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 sled dogging. His neighbors report that he is the neighborhood 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 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: None Shoe size: 17 White powder: baking soda
Peg	Fingerprints: loop Mouthprints: None Shoe size:15 White powder: salt
Jake	Fingerprints: whorl Mouthprints: None Shoe size:20 White powder: cornstarch
Lou	Fingerprints: arch Mouthprints: None Shoe size:16 White powder: sugar

Findings: ( what did you find. Summarise what you have written in the table above)
I find in the picture have a paper says I'm sorry, and I see the four people handwriting, and I find Lou Lou's handwriting is the same as the paper was on the ground, so I think is Lou Lou. But I find the chocolate on the ground the teeth impressions is the same as Dan.

Verdict: ( who is the burglar and why)

I find in the picture have a paper says I'm sorry, and I see the four people handwriting, and I find Lou Lou's handwriting is the same as the paper was on the ground, so I think is Lou Lou. But I find the chocolate on the ground the teeth impressions is the same as Dan. So I think is Dan and Loulou.

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.  Ruler

Steps:

1.  You need yourself and a buddy to help you measure your hight.
2.  And you need a 1 m ruler.
3.  And you measure you hight with the ruler.

Findings:

Name	Foot  (cm)	Height (cm)
Jeff	26 cm	1.45 cm
Kaedun	29 cm	1.56 cm
Ethan	24 cm	1.42 cm

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.
