What is radioactive dating? (such as carbon-14 dating). This Question Exploration help Ss explain half-life decay. Radioactive nuclei decay in different amounts of time based on their half-lives. Radioactive decay is the process by which a nucleus becomes stable. Question Exploration Routine is an instructional methods that teachers can use to help a diverse student population understand a body of content information by carefully answering a critical question to arrive at a main idea answer. Students taught using the question exploration routine earned higher total test scores than did students taught using the lecture-discussion method. Personally, I use the Question Exploration Routine to figure out what I want to say and how I want to say it. It keeps my "Sage on the Stage" time limited to what fits onto 2-3 pages (about 45 minutes of directed class discussion). This product includes the completed question exploration guide, and the student guide blanked except for vocabulary, scaffolding questions, and graphics already filled in. The resource also includes - a Do Now task to be used as a warm-up exercise or after-class review. - three student activities with problems to be used as laboratory exercises or as an after-class assessment review.

These scaffolded Radioactive Decay Cornell Doodle Notes combine two effective note-taking strategies and can be used to introduce the concepts of radioactivity and half-life, and the three types of radioactive decay (alpha, beta, and gamma). Students will learn what the word radioactive means, why atoms are radioactive, which elements have radioactive isotopes, the processes of transmutation by alpha and beta decay (using sample equations), that gamma rays are emitted during all decay, and the basics of the concept of half-life and radiocarbon dating. These notes support NGSS HS-PS1-8 (Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.) Cornell Notes are a note-taking strategy in which topic questions are written in a narrow left-hand column and definitions, explanations, and diagrams are filled in in the right-hand column. Doodle Notes (or Sketch Notes) are another note-taking strategy for which pictures and graphics activate the visual pathways of the brain, which helps with retention of information when compared to standard note-taking. Your visual learners will really benefit from seeing and coloring in the pictures aside the main points of the notes! I created a Powerpoint that goes with these notes. The Powerpoint walks the students through the lesson from the Essential Question and through all of the Topic Questions. There is a “Sum It Up” page at the end of the notes, for which students practice applying the concepts. On that page there is also a great ‘Quick Watch’ TED Ed video on radioactive decay that students will view. They will answer questions about the video to help sum up the new learning. The Cornell Doodle Notes are 4-pages plus 1 page for practicing with the concepts and there are 3 scaffolded versions plus the answer key included. The Powerpoint is included and there are also directions for accessing the presentation via Google Drive (Google Slides). This is obviously optional depending on how you choose to use this in your classroom. Learn how to separate the differentiated versions of these notes in your Google Drive and how to assign them digitally using Google Classroom by downloading THIS FREEBIE! Here are some ways that I suggest using this product: ✎ Whole-Group lesson with scaffolding : decide which students should receive which level of the notes. Hand out the notes to the students. Use the Powerpoint as a presentation and talk aloud through the lesson while the students take notes. Allow them to color/doodle further after each section and at the end of the lesson. {If you have a document camera (an ELMO), you can fill out your own notes and the students can follow along with you as you discuss the concepts aloud!} ✎ Scaffolded Small-Group lesson : separate your students into groups by learning level. Give each student group sets of the appropriate notes for their level. Make sure each group has a device to view the presentation. Post the Powerpoint or Google Slides to your Google Classroom or other online learning platform, or email the Powerpoint version to one ‘student leader’ in each group. The students would view the Powerpoint/Slides together on one device and fill in the notes. . Encourage them to add color/further notes. ✎ Individual Note-Taking or Flipped Classroom : Post the Powerpoint to your Google Classroom or other online learning platform or hand out the Google access directions to your students.. Hand out the appropriate-level notes to each student. Students can work at their own pace to view the presentation and complete their notes. Encourage them to add color/further notes.
