Planets in a Bottle -- sample lesson plan. Space Science News homeA SIMPLE LESSON PLAN FOR 2ND - 4TH GRADE CLASSES This is a prototype lesson plan for "Planet in a Bottle" yeast experiments intended for 2nd through 4th grade classrooms. We invite our readers to try the experiments (they are lots of fun) and we welcome comments from educators and others to improve our procedures. Please send comments and suggestions to james.a.phillips@earthlink.net. Objective: The student will measure the viability of yeast samples and to explore environmental conditions which affect the health of yeast microbes. The yeast samples may be common store-bought Baker's yeast, or more exotic forms which have been exposed to extreme environments as part of the Life on the Edge program.
Overview: Students mix yeast with a nutrient broth consisting of warm water and table sugar in a plastic water bottle. Materials: Procedure: Mix water + sugar in water bottle until the cubes are dissolved. This basic recipe can be considered an "Earth in a Bottle. " Sun, Light & Shadows - Science Games.

Pearson Prentice Hall Immersive Learning Simulations. ForgeFX has been a proud content development partner for Pearson Education for over 10 years. Developing over 100 simulation-based training programs and applications, across a number of different subjects and curricula, ForgeFX helps Pearson Education deliver digital learning products that transform students from passive audience members, to active participants in the learning process. 3D Wave Simulator This real-time 3D wave simulator demonstrates the connection between wind speed and ocean particle motion depth. The application helps students visualize how waves are the forward movement of water, due to the oscillation of water particles by the frictional drag of wind over the surface. Water motion simulator helps students visualize how ocean waves work. Pheromone Communication Simulation This is 3D simulator demonstrates how ants use pheromones to communicate.
