Good Morning! Thank you for having me in your classroom today. Mrs. LaRosa www.middleschoolscience.com
Your Challenge • Your group will be given 20 aliens to classify. • Choose one general characteristic to categorize your aliens into two large groups. Ex: has ‘abc’ and does not have ‘abc’. • Groups do nothave to have the same number of aliens in each. • Record your info on the chart provided.
Decide as a Group • After you have completed your two groups, split each group into two new groups. • Choose one characteristic to separate the first group. • Choose one characteristic to separate the second group. • You should have 4 groups when completed. • Continue splitting each group until you can no longer split them into new categories anymore.
Oh NO! I forgot about these aliens! Where do they go? Can you tell me where you would put them in your classification scheme? Start from the beginning of your chart.
Teacher Notes – by Liz LaRosa • This is the sample lesson that I used for my job interview – I got the job! http://www.middleschoolscience.com/aliens.ppt • This ppt slide was made using the following lesson plan: http://www.microbeworld.org/resources/experiment/pgs1-6.pdf • The chart that I made and used for this lesson is located at: http://www.middleschoolscience.com/aliens.pdf • Aliens were printed onto card stock and numbered from #1-20 and placed into plastic zip-top baggies. One set per group of students. • I chose only 2 of the 4 extra aliens to use at the end of the lesson if time allowed for the students to classify them. • The lesson was planned to last at least 45 minutes. I was able to complete most of the lesson, 60 -75 minutes would have allowed me to finish the lesson. • I taught this lesson to a 5th grade class of 18 students.
Tips • Discuss classification for a few minutes and ask students for examples. • Ask students for ways to tell the aliens apart, introduce the word characteristics. • Hand out the alien card sets after you have talked about what their challenge will be. • Have the students do their first sort and walk around the classroom and check on each table. • Make sure that the categories they have are very clear and specific. • When they are ready, ask for what categories they used. Each group may have something different and that’s OK. • Practice writing the data into the chart, make sure they understand what they have to do with their information and the alien cards. • Let the students continue to classify their aliens and monitor each group. • When they are done, ask students for some sample categories. • Choose one of the aliens randomly from the set and ask each group how they classified that alien from start to finish. • Introduce the aliens you “forgot” and give them a few minutes to figure out how to classify them. Did they fit? Any problems? Etc… • Have each group clean up by placing the aliens back into the baggies and then thank them for a great class! The kids really were engaged in this lesson plan, it was great!
