 The paper plane lifted High I through My plane and then it went High into the sky I thought that It would get stuck in the tree the highest distance that we got was 6.60 By the Cruiser plane The next one was 3.50 by The Glider plane and then My plane was the jet and that went 2.20   

White Powder Test

White Powder Test 

A forensic scientist may discover powder at a crime scene. In order to determine if it is illegal or not the crime lab will identify the substance using chemistry. Take on the role of a forensic chemist to identify unknown substances.

                                                                                               

Substance     Appearance   Texture    Smell     Water   Iodine

Cornflour = "B" Fine ---Smooth---Strong---Sitting their ----Make a big bubble 

Sugar = "D" Small----Rough---Nothing ---Devolved----Developed Fast  

Salt ="C" Really Small ---Rough---Bad---Devolved ----Devolved Fast 

Baking soda="A" Large ---Smooth---Weird---Stayed Still

Aim-To see how powder will react when Water and Iodine are top on to it
Summary - when The water was pored onto the 4 different kind of powders some would react in different way  then others  

Science...The case of the barefoot beefburger

In groups of 4 or five you are going to need to use your forensic knowledge to solve a crime.
Using the clues found at the crime scene, determine which of the four suspects is the "barefooted burglar"? 
What do you think was the motive for this crime? 
Write the results of your findings and convince a jury of your peers.

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.

• Sticky fingerprints were lifted from the aquarium and piggy bank. The painted footprints were measured. The chunk of chocolate candy was collected for examination. It appeared there were teeth imprints.
• The white powdery substance by the piggy bank was carefully placed in a plastic bag and taken to the forensic chemist for identification .

Name	Motive	Clues
Lou Lou	ceramic pigs.	always barefooted
Dan the man	trying to save money	Baking soda
Jack the jock	hands were dry
Peg the leg	super studious Liberian	same height as foot print ,Teeth chipped

Findings:  I found out that baking soda explode when it is mixed with vinegar and when you mix Salt and Vinegar together it bubbles so that mean that It was most likely to be Peg the Leg 

Verdict:

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

Name	Height	Foot Size
Summer	147	21 cm
Aroha	150	20 cm
Sahana	151	22 cm
Alesha	161	24 cm
Kayla	141	20 cm

My number is 13.3%

Kayla's answer is 14.1%

Sahana's Number is 14.9%

Summers number is 14.2%

Alesha's Number is 14.9% 

1.Aim- Based on someones Feet size we can measure their height

2. hypothesise-Know a rough estimate of our Height.

3.Method-Have the students in your group remove their shoes and measure their height.

4.Equipment-Mini Ruler Large Ruler and Calculate

5. Results-So today I found Out that My feet were 20 cm and My Height was 150

6.Summery- the police investigator and forensic scientist use 15%of a person foot length is equal to their to their height 

7.Conclusion-By Knowing what a person foot size is we can determine their approximate height  

Graph for science

Drawing Graphs in science

Rules

1. Always use a sharp pencil 
2. Use a ruler if drawing a line graph.
3. Choose scales so that the graph takes up at least 80% of the paper.
4. Label both axis with a description of what you are measuring.
5. Give your graph a title. 
6. Never rule back to zero.

1. Outline 2 features of a good graph? 

Straight lines, Labels ,Title 

2. Suggest why graphs should be drawn in pencil?

if you make a mistake you can rub it out 

3. What needs to be given a title on a graph?

your project, X axes , Y axes  

Using the graph paper provided graph the class results of your phone / Chromebook model.

Aim: To record, tabulate and graph data.

Hypothesis: I think that the most popular model is an I phone 5s / Acer Chromebook

Method: 

1. Note the make of your phone / Chromebook

2. Record your results on the whiteboard by ticking the appropriate box.

3. Record the class results in the table below.

4. Use the graph paper provided

• Draw a chart
• Graph the results 

Conclusion:
