All chemistry items in bedrock beta not present

The latest beta came with a education option in the cheats. Awesome! But when I opened it up on a world, it seemed fine at first, but all the features aren't there as they were shown in the livestream. Balloons, sea torches, sparklers, and other chemistry tools aren't there. Is this a bug or did they not release the whole chemistry options? Most of them are there, but not all of them shown.
