. #Biomes of the Earth for 7th Graders(This general database was designed to help 7th grade biology and ecology students learn the various biomes located on Earth. It will also aid in their distinguishing similarities and differences among the biomes. This database was designed to be used as an inquiry activity. To successfully integrate this database into an ecology lesson, use the following steps: 1. There is a Word document in the "Biomes7th" folder for students to use that is titled "Cheat Sheet." Students can use this handout as a helpful tool for navigating through the database. 2. In the "Biomes7th" folder, there is a folder called "Teacher Use Pics," where there are pictures of each of the nine included biomes. The instructor can open each image and post it at the front of the classroom for all students to see. Students are to use the database to key out and learn which biome it is they are viewing. (The reference section of this database may guide students to resources that can help them key out the biomes.) 3. The previous step can be repeated until all students have successfully determined which biome each image was depicting. 4. To check students' work, the students should click the check mark icon to show their steps at how they arrived at the biome they did. 5. Another way to assess student performance is by using the "Biomes Database Reflection" handout located in the "Biomes7th" folder. This Word document contains questions that requires students use critical thinking skills to analyze the database.
