The student will make inferences and explanations based on observations recorded using student-made model of the universe during an investigation using a balloon.
2 days @ 50 min/day
cooperative groups of 3-4 students
1.1, 1.3, 2.1, 2.2, 2.5, 3.1, 3.2, 3.5, 3.7, 4.2, 4.3, 5.2, 5.8, 7.2, 7.3, 7.4
|Lesson Components||Time||Inquiry Skills||Tech. Used||Engage Level||Brief Description|
|Engage||5 min (day 1)||1.1, 1.3||Proboard or smartboard, electronic devices||2||Students view and discuss a video clipabout our expanding universe. Then they contemplate if our universe has a boundary and if yes, what might be beyond that boundary.(Alternate also available)|
|Explore||30 min (day 1)||2.1, 2.2, 2.5, 3.1, 3.2, 3.5, 3.7, 4.2, 4.3, 5.2, 5.8, 7.3||none||3||Students use a balloon to model the universe. They draw three dots representing 3 galaxies in the universe and then blow up the balloon. Taking measurements, they begin to understand how it is that scientists come to believe that the universe is expanding.|
|Explain||15 min (day 1), 30 (day 2)||7.4||Optional Electronic Devices||2||Students read a piece of given text and use guided/active reading strategies to better understand the concept|
|Expand||10 min (day 2)||7.3||Optional Electronic Devices||3||Students can make a choice from the choice board to either create a radio show, create a travel brochure or make a song/rap about our expanding universe.|
|Evaluate||10 min (day 2)||7.2, 7.3||Optional Electronic Devices||2||Students complete a chart with the data from the explore stage. Then students respond to active reading questions as formative assessment and complete a review as a summative assessment.|
|Level of Student Engagement|
|1||Low||Listen to lecture, observe the teacher, individual reading, teacher demonstration, teacher-centered instruction|
|2||Medium||Raise questions, lecture with discussion, record data, make predictions, technology interaction with assistance|
|3||High||Hands-on activity or inquiry; critique others, draw conclusions, make connections, problem-solve, student-centered|
Please share your comments (e.g., strengths, areas for improvement, your implementation results if you taught the lesson in your class, and any modifications you made). Thanks!
