What's in your Mix?
Give students a cup of trail mix.
Describe the ingredients and physical properties of the mixture, including mass, magnetism, and sink/float (will do as a class demonstration rather than have each group sink/float their samples of trail mix)
Separate the ingredients of the mixture.
Describe how the ingredients change/stay the same when mixed together and separated.
Watch presentation on Mixtures and discuss the ingredients of each and physical properties observed.
- Choose two materials from a teacher-provided selection (e.g., gravel and sand, metal and plastic paper clips, water and pepper, etc).
- Measure, test, and record the physical properties for both materials, including: mass, magnetism, sink/float
- Take photos of your investigation as steps are performed
- Once all data is recorded, combine the two materials.
- Observe the mixture and write a short paragraph describing how the physical properties of the mixture compare to the physical properties of the original materials.
- Determine whether a mixture or solution was created and explain why
Watch the following video from you on mixtures and solutions and how to separate the matter in each
- Evaluate methods for separating mixture/solution, including magnetism, sink/float, and straining. First separate by hand and time how long it takes. Then using each of the separation methods, separate the mixture/solution if possible and time each one to find the best method.
Using the pictures taken during investigation, students will create a digital presentation of what they have learned during this lesson. Be sure to include vocabulary discussed and learned during the lesson (at least 3 words)
*Physical properties of each ingredient, including mass, magnetism, and sink/float
*Physical properties of mixture/solution
*Best method for separating mixture/solution
*With another group, compare/contrast mixture and solution OR compare/contrast mixture and solution using VennDiagram (or another digital app) app
