My FACS students today made goop. I LOVE this mini-lab. I give them the recipe you see below. That's all. They make it. Below are some pics of the results. It is amazing how each group turns out sooooo differently. It is supposed to look like peanut butter bars, but they rarely end up looking like they should. After the mini-lab we talk about the importance of measuring accurately. They always have a good time with this lab, even if the product doesn't look appetizing.
