An Inquiry Chart, or I-chart, is defined by Reading Rockets as "a strategy that enables students to gather information about a topic from several sources. Teachers design the I-chart around several questions about a topic. Students read or listen to several sources on the topic and record answers to the posed questions within the I-chart."
Depending on the grade level, the teacher can provide the questions, or the students could create their own. The sources should not be limited to simply text and instruction. For example, videos make a great resource for I-charts. Also depending on the grade level, students could be assigned sources, or choose their own.
Below is an example of a completed science Inquiry Chart on the topic of weather.
