Unit II - Basic Minerals Macro and Trace

Pre-Assessment
As a pre-assessment give each group of students a set of cards with:

1. the names of minerals printed 
2. picture drawings of the food sources for each mineral.

Instructions: 

PART A:  Have the students match the mineral card to its most common food source.  Check to see how each group did and then discuss.

PART B:  Instruct students to take out the picture cards and set them aside.  SORT the mineral cards into Macrominerals and Trace minerals.  (See background information for list.)

PART C:  Have a third set of cards with the functions of each mineral for the students to match.

VARIATION:  In a big basket place several different fruits and vegetables.  Make several cards labeled with major minerals.  Place them on the counter.  Have volunteers place each fruit and vegetable in front of the card that indicates the mineral it is most abundant in.  The rest of the class can help the volunteer determine the placement of the fruit or vegetable.
