Computer-based Lesson - Mass and Density  by Kathy Martin

 

Integrating Computer Technology into the Classroom Final Activity

 

Title:                  Mass and Density

 

Learner Level:  GED     

 

Pre-Instruction:

Distribute copies of Fearon’s General Science chapter 14, vocabulary preview. Discuss with class the most basic questions about the universe. What is matter? What is energy? How are they related?

                          

Duration:           Three days for two hours each.    

     

Materials:

GED Science Connection KET PBS Literacylink Video(23), books, handouts, computers, Internet connection, Plato and varies materials for guided discovery activites.

Objectives: 

Students will investigate the properties of mass and density. Students will develop and utilize skills on observing, predicting and testing.

Procedure:

  1. The students will review the concepts of heavy versus light and the concept of sinking versus floating. Use guided discovery activities, density drips, fruit floats. Do activities in class. http://www.doscience.com/act_archive/home_activities/fruit_float/index.html

  1. Have the students work in groups to test various objects to determine whether or not objects will sink or float. (objects such as coins, rocks, rubber stoppers, pieces of wood, cork, etc.)

  2. Have students record the results on their handout sheet. Ask the students, “What reason do you give for the results of your experiment?”

Class will go to    http://www.eoascientific.com/campus/science/multimedia/weight_mass/view_interactive

  

Evaluation:

Observing students with guided activities. Students will turn in data sheets of their handout.
