This activity teaches students about the periodic table and how element properties can be predicted through periodic trends.

In this cooperative activity, students use microscale reaction plates and straws of different lengths to construct three-dimensional bar-type charts of element properties. Let students discover for themselves the existence and direction of periodic trends.

What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water.

This activity is a summary/assessment assignment which allows for differentiation and student choice. Students are assessed in their knowledge of the atomic model and the arrangement of elements on the periodic table.

Students will classify elements as metals, non-metals and metalloids based on their observtions of appearance, conductivity, malleability and reactivity with dilute acid. They will observe the location of these groups on the periodic table.

This lesson plan examines the properties of elements and the periodic table. Students learn the basic definition of an element and the 18 elements that build most of the matter in the universe. The periodic table is described as one method of organization for the elements. The concepts of physical and chemical properties are also reviewed.

Students will fill in a blank periodic table for elements 1-20 using electron-dot models. As a visual tool students should see several periodic trends.
