Demonstrate the parts of a flower in plant science lessons with this durable foam tulip model. One half of cross-section is labeled with part names (stamen, petal, pistil, sepal, stem, leaf and roots); other half is labeled with letters for assessment activities. For more detailed study, Activity Guide features discussion and labeled drawing of additional flower parts, including filament, anthers, stigma, style and ovary. Foam model wipes clean and measures approximately 6" H. Ages 7-11.
This model of a plant cell splits in half to provide a cross-section view and make learning the parts of a plant cell easy. One half of the colorful foam model is labeled with the parts of the cell, and the other is labeled with letters only. Included Activity Guide provides detailed information on plant cells. Ages 7-11.
Using the Crucible Cradle will help alleviate many of the problems associated with the proper handling of the crucible. You can now eliminate the need for the use of crucible tongs. Many students find the use of tongs awkward and end up dropping the crucible. The Cradle will also eliminate the need to touch the crucible after it has been heated. Oils from the finger tips can add weight to your final results, and throw off your findings.
