Series of eight plastic raised relief models. Relates typical surface formations to subsurface structures that are shown as graphic cross sections on each model. Helps students to better understand the development of the landscape and the factor and force influencing the development. Geologic features are numbered and keyed to a comprehensive study guide. When combined, the 8 individual models form a continuous 8-foot long graphic landscape and landform reference. Each model is 12" x 15", printed in full color on durable plastic, thermo-formed and reinforced with rigid foam.
Without sacrificing size or key detail this three-part replica exposes the entire length of the ear canal and Eustachian tube so that the sound waves entering the ear can be easily traced and to demonstrate how air pressure on both sides of the eardrum is equalized. The hammer, anvil, transparent ear drum, and the labyrinth all lift out for hands-on study. 18 hand-numbered anatomical features are explained in-depth in the accompanying study guide.
Six times life-size with five detachable parts including the upper hemisphere, the iris/cornea unit, the Lucite Lens that magnifies and inverts images, the transparent vitreous body, and the retina. The eyeball disassembles and reassembles with ease, so students can effectively learn through hands-on activity. A 2-page study guide highlighting its 19 principal features is included. Overall dimensions: 6x6x6 inches (15x15x15 cm) overall.

Inquiry-based activities covering the basics of electricity. Perform a variety of hands-on investigations to study the properties of electricity. Students will explore the concepts of electric currents, open and closed circuits, and series and parallel circuits. They?ll also investigate static electricity using an electroscope. The students will apply the knowledge gleaned from these activities to classify materials as either conductors or insulators of electricity and electrical power. Your students will understand concepts of electrical charge, current, resistance and voltage. Understand the concept of electric circuit and power. Distinguish between resistors in series and parallel. Classify materials as electrical conductors or insulators. Identify cases from everyday life where electricity is being used. Class Size: 40 Students. Grades 7-10
