Grade 12
Mini Mystery Boxes
This lesson is designed to help students better understand the nature of science. It uses simple, readily available mini-mystery boxes to model how scientists study things they cannot see (see http://www.lab-aids.com/catalog.php?item=100). Scientists often study things that cannot be seen - either because they are incredibly small (inside of cells/atoms) or too far away (other galaxies). In such work, scientists must rely on indirect information. Mystery boxes – each with a small steel ball and a raised terrain inside – demonstrate this aspect of science to participants. The students will draw a model and discuss in groups what they think the box looks like inside.

Mystery Box
This lesson is designed to help students better understand the nature of science. It uses a Mystery Box (see attached photos) which has a funnel at the top and a beaker underneath. When water is poured into the top funnel, colored water flows out the bottom. A turn of the funnel and then pouring in more water results in either a different colored water or no water at all. The teacher demonstrates this Mystery Box to students and challenges them to propose models of the inside of the box. The students draw models of what they think the inside of the box looks like and share and discuss these models. Students can also construct their own mystery box using cardboard boxes and other common materials. For this option, you will need an additional class period.

Detecting Photosynthesis- Analyzing Other Scientists' Data
Students will analyze the results of another scientist's experiment by examining leaves that have been exposed to different treatments, and draw conclusions about the process of photosynthesis.

Students will be able to see the iron filings in breakfast cereal fortified with iron and qualitatively compare the iron content between 2 different cereals. They will also see that as part of a salt solution, some elements give off characteristic colors when placed in a flame.
