Earth Science Mega Set
Part of the National Geographic Mega Science Series, the Earth Science Kit brings together more than 15 hands-on activities in one box. Students grow a crystal in as little as three days, build and paint their own volcano and set off several types of eruptions, and use tornado tubes to create water vortices and race them against each other. Two dig kits let learners excavate a rose quartz specimen and pyrite specimens, while a selenite piece shows how some minerals let light pass through. A starter rock collection introduces specimens such as snowflake obsidian, tiger's eye, green fluorite, pumice, desert rose, blue calcite, agate and geodes. A full-color learning guide explains the science behind crystals, volcanoes, tornadoes and gemstones. With so many separate activities, the kit works well for group rotations, earth science units or home-school study.
