Microscopic Comparison1. Look at each fiber under the microscope.

2. Make your observations of each fiber

Combustion Test1. Pick up one fiber at a time with a tweezers and place

that fiber in the fire.

2. Burn each fiber

3. Observe what happens

Handwriting Analysis

• Matching the handwriting

•Hello My name is Susan.•Hello My name is Susan•Hello My name is Susan•Hello My name is Susan

Ink Analysis

• Chromatography Method– Chromatography is a method of

separating out materials from a mixture. Ink is a mixture of several dyes and can be separated by using certain types of solvents.

– If the dot moves than the dot is soluble in that solvent.

Water Analysis

• Phenolphthalein will react in the present of a strong base.

Victim TabithaIt all started a couple of days ago when funny things started to happen. Our victim Tabitha ,a canine groomer, started to use a particular soap that had a wonderful scent. Tabitha worked at a pet salon which was located on the top of a hill that was above a controversial reptile farm. All of the sudden Snappy the star alligator was found belly up. Snappy’s body was covered with the same scent of the special soap. Tabitha was very upset about this and called a gathering, where the primary reason for meeting was about Snappy’s death. During that time, the Skydiving association was meeting at the same location. The location of the gathering was held at Mt. Sequoia. The Skydiving experts did not want to share Mt. Sequoia and an argument started.
