Quick Frozen Critters is widely popular elementary school lesson on wildlife adaptations and the food chain that comes from our friends at Project WILD. In addition to being educational, it is active, aerobic and immensely entertaining for children (and adults). Although the focus is on wildlife and the food chain; core science concepts in Texas elementary schools, this particular activity is infinitely adaptable across content areas. There are some great mathematics concepts (graphing population curves, predicting outcomes, fractions, percentages etc.) as well as some really cool social studies themes. In one session I held, the students began thinking about human-related influences on wildlife population...such as development, roads, and diminishing habitats. Although the lesson content is best suited for elementary school, I've also used this with high school and college students.
If you're like a lot of teachers, particularly in Texas, who struggle with just trying to teach to the standardized test and faced with the challenge of constantly having to apply for authorization to use anything new in the classroom...here is an option. During recess..why not play the game with your students...and then apply what they learned having fun, in the classroom to supplement a pre-approved lesson? Remember, it's not just educational...it's fun and recreational. Maybe even talk to the PE coach, ask him to play the game with your students. Even if you can't get it approved as an educational resource, use it as a supplemental and recreational one.
Basically what I am saying is; there's no excuse....so have fun!
