Super Cool Lesson Plan

Topic: Buoyancy in objects for First Grade

Objective: By the end of the lesson, the students will know about buoyancy and be able to identify what objects will float and which will sink.

Lesson: Present objects to the class, each of different buoyancy levels. With a see-through bin filled with water, have the class guess what objects will float and which ones will not. After every object has been predicted, begin dropping them in the water one at a time. After each object allow the class to talk with a partner and see if their predictions were right, and talk about why they think they were wrong, or how they guessed correctly. After that, explain what buoyancy is and how it makes objects float and sink. Afterwards, split the class into small groups and have them do their own float or sink test with different objects. Making sure to assist struggling students (and make sure there is no mess being made).

Assessment: After the groups complete their own tests, give them all a handout featuring different objects. Have the students select which ones will float, and which ones will sink. Making sure to walk around the classroom and provide assistance to students when necessary. For students who want an extra "challenge", have them think up objects and explain why they feel they will float or sink.

Closing: After everyone has completed their handout, gather the class and review the concept of buoyancy. Afterwards, ask students if they were surprised by any of the results.

Supplies: Various classroom objects, multiple clear bins, buoyancy handout.

      Michael,

      This is a perennial favorite. 

      For your learning objectives, you say that students should be able to name which objects will sink and which will float. Is there anything else you want them to learn?
