Which type should you use with¥A Compound Microscopevery thin you can see through it(things like strands of hair, glass slides or blades of grass)¥A Dissecting Microscopeyou canÕt see through it3.Put your object on the microscopeÕs Try turning the . Is it really dark? Make certain that the microscopeÕs on.

They discovered that we weresurrounded by strange creatures that were too small to see. In this activity, students will discover new things about ordinaryMinimum Materials Needed for Each Student Group:Pre-Activity Preparations: 1.Have the students select two objects to bring in from home.2.Have the students complete the homework page for their two objects.
