The National Geographic junior metal detector is designed for beginners. It has a 7.4-inch waterproof dual coil that can detect metal objects up to about 6 inches below the surface, with adjustable sensitivity. When a target is found, the detector beeps and shows the result on an easy-to-read LCD screen.
It offers three selectable detection modes and a pinpoint function for locating a target more precisely once an area has been found. Weighing about 1.4 pounds, it has a telescoping arm and comfort grip, and folds down with a removable arm support for storage. A trowel is included for digging up finds.
The full-color learning guide covers the science and history of metal detecting. Schools can use it for outdoor investigations on magnetism and electromagnetism, or for hidden-object searches on the school grounds.

The National Geographic Magic Chemistry Set combines science and showmanship. Students carry out 10 experiments that are each designed to be performed as a magic trick, such as making a coin float, changing the color of water and making snow appear from a powder. The kit supplies hydrophobic sand, instant snow powder, red cabbage powder, citric acid and sodium bicarbonate, along with a beaker, pipette, copper coins, clear and paper cups, pH indicator paper, cotton gloves, a magic wand and an experiment guide. There is enough material to practise each experiment once or twice before performing it for an audience. The illustrated guide gives step-by-step instructions and explains the chemistry and physics behind every effect, making the set a good fit for science clubs, enrichment sessions or a class science show where students present and explain their results.
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.
