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 gold fish were gasping in the sink. Beside 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 were 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: Beaver Teeth Shoe size: 11.7 White powder: Baking soda.
Peg	Fingerprints: Loop Mouthprints: Chipped tooth Shoe size: 10.1 White powder: Salt
Jake	Fingerprints: whorl Mouthprints: knocked his front tooth out shoe size: 13.4 White powder: Cornstarch
Lou	Fingerprints: Acrh Mouthprints: Nothing Shoe size: 10.6 White powder: Sugar

Suspect:

Fingerprints: Loop.
Mouthprints: Beaver Teeth.
Shoe size: 10.6.
White powder: Baking soda.

Findings: ( what did you find. Summarise what you have written in the table above)

Verdict: ( who is the burglar and why)

Conclusion: 

This is the second experiment we have done today. This experiment was really interesting. I think for the suspects is 2 people not one. I think it is Dan the man and Lou Lou.

Because Beaver Teeth and Baking soda are the same with Dan the man and Lou Lou shoes size is 10.6 and fingerprints are loop and that is what Lou Lou has. So I think it is both of them. If you think it is something different tell me.

Forensic-Feet Height /Science

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. Ruler.
2.  A friend.

Steps:

1.  Get a Ruler.
2.  Measure your Height or Foot.
3.  Put you're measure on your chart.

Findings:

Name	Foot  (cm)	Height (cm)
Janel	28cm- 17.00.	159cm.
Keyana	23cm- 14.5.	154cm.

Divide the length of each person's foot by his/her height. then multiply it by 100. 

Conclusion: 

Today in this experiment we did something different, we did a measure experiment but we had to measure our foot and height. Today was really interesting to found out my Foot and Height measure. What we did to found out our measure was a ruler. 

Me and my buddy Janel didn't have the same measure. Hope you could do this experiment and found out you're measure. I hope you enjoy this blog post and it would be kind if you say something in the comments.

Finger prints

Fingerprint characteristics

Aim: To look at the different types of fingerprints.

Materials: 

1. Balloon.
2. Fingers.
3. Ink Pads.

Steps

1. Roll your finger onto the Ink Pad.

3. Blow up the balloom.
4. Look at the balloom and see what tip of fingerprint you have.  
5. Take a photo. 
6. Pick what fingerprint you have.
7. Put your photo on your blog post. 

Insert two pictures here of your fingerprints

Ink prints

Thumb print	Index finger print

Record the types of fingerprints from those in your group.

Name	Fingerprint 1 (Thumb)	Fingerprint 2 (index finger)
Keyana	Loop	Didn't do it
Anneleise	Didn't do it	Loop

Questions:

Do people always have the same type of fingerprint on their thumb and index finger?- No

What was the most common type of fingerprint in your group?- Loop

Dusting fingerprints:

Lifting fingerprints

Aim: To learn how to lift hidden fingerprints from an object.

1. Lifting and Gathering fingerprints.

Equipment:

1. Plastic.
2. White powder. 
3. Brush.
4. Black Paper.
5.  Tape.

Method: 

1.  Get plasitc paper.
2. Get the white powder. 
3. Get the brush and dip it in the white powder carefully.
4.  Brush the powder all over the plastic paper.
5.  Get black paper and place the plasitc over it.
6.  Get some tape and put it over of your fingerprint. 
7.  Take a photo.

Results:

Lifted fingerprints

Thumb print	Index finger print
Loop	Whorl

Conclusion Questions:

Today in science we did a fingerprint with ink and white powder experiment. 

(Ink Pads)- We have been finding out what type of fingerprints we have and I found out today that me and my buddy have the same fingerprint but on different fingers. We both got a loop and what we used to find out our fingerprints was from a ink pad.

(White powder)- We had to find out what type of fingerprint we have in the white powder. The white powder was really mess but we ended up making a really good fingerprints. Me and my buddy didn't have the same fingerprints this time. 

Hope you enjoy and I will be posting all of these kind of blog post. 

What could you do to improve your results next time?- I could impove our fingerprints because we couldn't really see what type of fingerprints we have.

Why do you think fingerprints are useful to crime scene investigators?- So the investigators can go find the person who was guilty for there situations.
