elf esl steam kits

 Not only do students learn important concepts through STEAM education  (Science, Technology, Engineering, Art, Math), but they can also improve their 4 basic English skills (listening, speaking, reading, writing). Learning English as a second language or foreign language through other subjects (also known as CLIL) is a popular way to teach EFL/ESL, which is one reason why our STEAM Kits are so popular with English teachers and parents alike.

Each Glowing Black Light Slime STEAM Kit includes a carefully crafted lesson plan that’s suitable for a wide range of ages and skill levels. The STEAM-based English lesson is built around 4 pages of worksheets which teach the vocabulary used when making glowing black light slime, explain the steps required to make it, introduce a sub-topic (learning what objects glow under a UV black light), and include a fun true-or-false quiz with 6 questions related to the STEAM topic of the kit, UV light.

The BBbots STEAM Zone makes learning fun with online games, activities, and lesson videos!
