The Jelly Bean Problem

Rise and shine! Class members collaborate to construct a photovoltaic solar cell with two semiconductor layers, as guided by this fabulous lab sheet. They test its output with an ammeter or galvanometer. 

Energize the cells of young biologists with an edible life science activity. Engaging students in exploring the inner workings of plant and animal cells, this activity involves using colored jello and various sweet and...

Intended to supplement your existing cell function and organelle lessons, pairs work together to develop a real-world analogy for cell structures. In addition to writing paragraphs about the comparison, each group will make a short...

Pregnant women exposed to PAH air pollution increase the risk of obesity in their children. The example of epigenetics, along with others, builds the basis for understanding the process of cell differentiation. Scholars view a video,...

Engineering enthusiasts are sure to explode in understanding as they practice the engineering design process (EDP). A container of "toxic popcorn" is placed in the classroom. Teams must work together to devise a method for removing it...

Cell membranes contain many contradictions; for example, they are both oily and strong. The video explains the parts of a cell membrane, the function of each part, and discusses the contradictions. It highlights what happens when...

Use this resource to have your class learn about the cell. This resource walks learners through the construction of a model of a cell. This project is completed in a cooperative learning group, and  reinforces the higher-order...

Liken a cell and its organelles to a tiny person and its organs. After gathering information on cell structures and their functions, small groups collaborate to come up with an analogy of their own. They produce a collage describing the...

Does cell size have something to do with magic? No, but their size has everything to do with geometry. The video explores an analysis of two cylinder's volumes, showing how surface area affects volume. Learners see how in biology,...

Cells demonstrate a life cycle like other living things, but what if death was no longer part of the cycle? Learn about the important balance requiring death to continue functioning. An online interactive introduces a group of scientists...
