1 Hook

Activity: Investigating

Place a variety of elements (identities not revealed) out for students to investigate (metals, nonmetals and metalloids) and give them a variety of different things they can test various physical properties (physical state, density, luster, electrical conductivity) and make predictions beforehand of which are metals, nonmetals or metalloids.

2 Direct Instruction

Activity: Presenting

Students will then define what a metal, nonmetal, and metalloid are and compare / contrast the basic physical properties that they all share.  Students will use a foldable (graphic organizer) to compare / contrast properties of each type.  

Then we will incorporate knowledge of how the organization of the periodic table fits into this schema.  A very brief introduction of the periodic table and how the "staircase" separates the metals from the nonmetals will be introduced.  Additionally, we will identify the 7 metalloids that border the "staircase" on the PT.

3 Guided Practice

Students will complete a WebQuest using this basic app.  Get familiar with the elements using this effective app. The teacher will walk students through this app and scaffold how to determine whether or not an element is a metal, nonmetal, or metalloid. 

4 Independent Practice

Students will continue this WebQuest and begin the Independent Practice section of this.  There will be a couple sections within the independent practice.  IDENTIFY: One part I will just list the element and the student must identify whether it is a metal, nonmetal, or metalloid based on location it is found in the periodic table.  ELEMENT WHO AM I?: The next part, I will give a few clues (physical state, melting point, density, conductivity, picture of element) about a particular element, and students must identify whether it is a metal, nonmetal, or metalloid and also identify the correct elelemt based on the clues.

5 Wrap-Up

Activity: Assessing

Based on their knolwedge of what they've learned about the properties of metals, nonmetals and metalloids, students will go back to the same set of elements placed out in lab and try to accurately identify whether each element is a metal, nonmetal, or metalloid based on the properties each element possesses.  Additionally, other clues (melting point, density, conductivity, physical state) will be given to the student to aid in the correct identification of the element.  Students will be graded on their accuracy in determining the correct identity of each element and whether it is a metal, nonmetal, or metalloid.
