This is a demonstration of carbon dioxide's solubility into an aqueous solution. A candle and beaker of pink phenolphthalein solution are placed inside a jar. The candle is lit and the jar is capped. The flame expectedly goes out as the oxygen is depleted. After the flame is extinguished, the pink solution slowly fades to colorless.
Students are asked to design a Cartesian Diver from a list of materials. The lesson hand-out includes all materials needed, steps for construction, and list of resources to help with designing and understanding the concepts involved in the creation of the divers. The challenge is then to make three different divers that dive in a predicted order.
This is a lab safety contract provided at the beginning of each semester to all science students.
When a drop of Duco brand cement is placed in a container of water displayed on an overhead projector it appears to be a single celled organism swimming and interacting in the container. Students, who are unaware what was added to the water, engage in a discussion to determine if the 'Glue Monster' is alive or not.
The Organizing Data POGIL is designed to allow students to discover the difference between the dependent and independent variables, and on how to handle data from labwork. Â The activity goes on further to address various methods of graphing data including line graphs through bar. Â The POGIL forms an excellent basis for preparation for the ACT exam science component and similar assessments.
In this cooperative activity, students use microscale reaction plates and straws of different lengths to construct three-dimensional bar-type charts of element properties. Let students discover for themselves the existence and direction of periodic trends.
