My kiddos had the opportunity to review Spark Lab ~ Inventor's Studio.
Overall, this product was fun and my kiddos literally used every piece of material included to create until nothing was left. They really enjoyed using their imaginations to invent and create. For the price, $24.99 on Amazon, I really think that more building materials should have been included. I really hate to give unfavorable reviews but I feel that honesty is what my readers deserve.
The popsicle sticks are cardboard, not wood. The paper squares, while colorful, are lightweight paper.
One could easily go to the Dollar Store and purchase a basketful of materials equivalent to the ones in this kit that would not only be cheaper but provide a larger variety of materials.
The Inventor's Guide was somewhat helpful but really not anything that contributed to what a child can naturally think to create on their own. The Inventor's Notebook is pretty much a booklet of blank and grid paper.
I supplemented the contents of this kit with glue dots and Scotch Tape.
I received this product for free in exchange for my honest opinion.
