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.

Become a Forensic Chemist by following these procedures and filling in the Powder Analysis Chart with your results. 

Complete the appearance, texture, and smell activities before opening the vinegar and iodine bottles.

Record your findings in the Powder Analysis Chart below.

Aim: To determine how different powders feel, look and react to other substances.

Hypothesis: 

Equipment:

Baking Soda
Cornflour
Sugar
Salt
Iodine
Vinegar
Magnifying glass
Eyedrop
Black card
Tea spoon / stick

Method: 

1. Place one-fourth teaspoon (1 ml) of the four white powders on a sheet of black construction paper. Label the powders with your pen.
2. Study the powders with the magnifying glass. Examine what each powder looks like. How would you describe the powder's shape. Does it have large or small grains? Your observations should be written in the appearance column of the chart.
3. Examine the powders further by rubbing each powder between your fingers. Describe how each powder feels in the Texture column of the chart.
4. Determine if there is a smell to any of the powders. Record your findings in the Smell column of the chart.
5. Take the eyedropper and place a drop of water on each individual powder. Examine what happens? Do the powders dissolve? Is there a reaction? Write your observations in the Reaction to Water column.
6. Place one-half teaspoon (2ml) of each powder in a separate jar. Add 2 drops of iodine to each jar using the eyedropper. Record what happens in the Reaction to Iodine column. Iodine should be handled with care.

We have been working on a Presentation on Hornby High School. I have enjoyed creating it.The best bit I  liked doing was putting in the gifs and telling people about how amazing this school is.
We have also been learning about the Community.
What a Community is? What makes it a Community?
 A Community is a place where we feel like we belong and places like a school, sports clubs, shops, friends, churches and work places  are part of the making of a Community.
