This box was wonderful! Hands down favorite. Saving Our Oceans......The box comes with multiple different experiments. Came neatly packed with almost all materials, additional simple materials needed are standard home items: measuring spoons, water everything else was provided in the box. Also comes with a Lab Notebooks, detailed step by step instructions of each experiment, a small stuffed animal. We made bioplastic, did an experiment on packing peanuts: comparing biodegradable and non-biodegradable materials, preformed a nature project on Ocean Light Zones and the creatures that inhabit them. This one came with three glass bottles that once the experiment was done makes a nice keepsake. There are several other experiments still to do and I look forward to working through them with my son too. It's an excellent introduction to science vocabulary, too! Well done.
