Science Tasks with Otis & Flask were designed as centers to reinforce science concepts in grades 3-6. These centers include Teacher Background information, Task Cards for each center that provide information for the student, photocopy-ready student packet pages which many include student observation sheets, data sheets, student readings, vocabulary, and assessment items. An answer key is also included.
The Teacher Guide for all the centers is available as a FREE download. This gives detailed information about the set-up of each center, and content addressed in each center as well.
This activity is an introductory lesson on rocks that gives students an opportunity to develop skills in comparing the similarities and the differences in properties of rocks. Activities include hands-on observations and readings. In these activities, students compare properties, or characteristics, of rocks. It is a critical skill to develop because in later grades they will use properties to identify minerals (e.g., Mohs hardness test) and to explain types of rocks (i.e., sedimentary, igneous and metamorphic).
