Science - Chemistry
Standard 3 Objective 3
1 class periods of 30 minutes each
Students will compare the shapes of the ammonia, methane, and water molecules.
The information sheet for the students is attached. Have a designated area for the students to bring their projects because they are often too big for the room. Putting signs on tables with the period number in the back of the room is helpful. This makes it easier for the students to find it when they present their projects,
This is given mostly as a homework assignment but a few minutes can be given to let the students bring in materials and work or prepare their project. Plan about ten minutes to introduce the assignment and some time to let the students presents their projects to the class (depending on class size).
This assignment can be used as an assessment or review for the students. They should know how covalent compounds form bonds and how to draw them. The students should also know how to draw the three dimensional structures of the water, methane, and ammonia molecules.
While the students present their projects, use the list below and grade their projects. Make sure the students point out the 2-d structures, 3-D shapes, and 3-D geometries along with the names of the molecules.
