Imagination has no boundaries with these STEAM-compliant science-adventure kits from Tedco Toys, though it does have a number—(8). That’s how many activities each kit includes. Some common household items are required, and a full-color instruction guide is included. Ages 10+. You pick: the Pressure Lab Fizzy Adventure Kit, which helps kids learn about acids, bases, chemical reactions, air pressure and thrust by mixing everyday ingredients to make foam, a reaction racer, fizz missile, soda blaster and more; or the Human Body Anatomy Adventure Kit, which helps kids explore the human body from head to toe, by studying major organs in the torso, doing up-close teeth examinations, discovering how taste buds work, building a DNA strand and more.
