An engaging lesson that provides everything your students need to learn the basics of Forensic Powder Evidence. The Powder Evidence Lesson includes interactive Google Slides, student notes, a powder lab and review questions!

Your students will learn…

• The value of powder evidence to forensics
• How to collect powder evidence
• Methods for powder analysis used in the Crime Lab 
• Details of 7 powder tests that they will perform in their own powder lab
• Identify as many as 11 different white powders in the hands-on powder lab
• Test their new knowledge with a 10 questions Google Form review 

Included in this Powder Evidence Lesson:

• 39 Interactive Google Slides teaching Powder Evidence + Key
• Student notes + Key
• Student Lab sheet
• Powder Reference Table - multiple versions to choose from depending on how many powders and tests you want to / can do 
• Printable lab instructions for students 
• 10 questions on a self grading Google Form - use for review or assessment
• Teaching Guide with details about everything! 

How your students will learn:

Students work through 39 interactive Google Slides. Slides ask them to drag and drop, organize images, watch short video clips, and think through information. The interactivity keeps them engaged in learning! Slides can be 100% student led, or you can use them for lecture, or a mix of both. 

As they work through the slides, students will complete their notes. Student notes ask them to think through the information, not merely copy and paste or fill in the blank. Slides include details and how-to steps for completing the Powder Lab.

In the hands-on Powder Lab, your students are tasked with identifying up to 11 white powders by performing and analyzing the results of up to seven tests. 

Powders include: 

• Cornstarch 
• Calcium Sulfate 
• Calcium Carbonate 
• Potassium Chloride
• Calcium Nitrate 
• Epsom Salts
• Table Salt (Sodium Chloride) 
• Glucose
• Sodium Acetate
• Baking Soda (Sodium Bicarbonate) 
• Sodium Carbonate

Tests Include:

• Observations
• Solubility in water
• pH Test
• Reaction with iodine
• Reaction with acid
• Reaction in Benedict's solution 
• Flame Test

Then, test your students’ knowledge with the 10 question Google Form. Use it for review or for an assessment.

This resource includes a comprehensive Teaching Guide with tips and tricks for making the lab as stress-free as possible. There are several versions of the lab that serve to reduce the amount of time and/or resources required - including versions that do not include the flame test or the benedict's solution test - and/or use fewer powders. Flexible for any classroom!
