This discrepant event focuses on the properties of index of refraction. 

Both jars appear to have none-one glass object suspended by a popcicle stick. Although both jars seemingly look like they are filled with the same substance, the first jar is full of water and the second houses baby oil. Due to both the glass object and the oil having a similar index of refraction, both glass objects in the second beaker appear clear or totally invisible! 

This discrepant event focuses on runoff and groundwater pollution. 

Two boxes filled with sand and a piece of foil showcased how rainwater (spray bottle) interacts with permeable and non-permeable surfaces. Once students saw the movement of the water, we discussed the repercussions of pollutants, and the teachers introduced food dye (pollutants) to showcase the harmful effects of runoff pollution. 

This discrepant event modeled lunar and solar eclipses. 

In small groups, students were instructed to model the location of the Sun, earth, and moon relative to one another in the context of both lunar and solar eclipses using Play-Doh. 

This discrepant event portrayed protein denaturing.

One egg was submerged in acetone, while the other was placed in water. The egg in acetone "cooked," leading into a discussion on enzymes and their effects on proteins in solution.  

This discrepant event allowed students to directly experience a chemical reaction. 

Students ate a "zotz" candy, experiencing several fizzing and popping sensations to play a role in a chemical reaction and experience firsthand its effects. 

This discrepant event demonstrated reaction rates and different affecting factors. 

Hydrogen peroxide was added to a catalyst (yeast in water), creating a foamy "tooth paste." The rate of this reaction was affected by the activation (or lack thereof) of the catalyst.  

This discrepant event delved into the properties of combustion reactions. 

A dollar bill was dipped into a solution consisting of 50% water and 50% ethanol, which was then set on fire. The dollar bill did not burn, however, due to the alcohol being burned off during the reaction instead!
