Review: This fun site is part of the online presence of the Children´s Museum of Indianapolis. The site contains three investigations involving Rex the Dinosaur, into pumice/volcanicity, fossils and rocks/minerals. The site also has a section on FAQs about rocks and fossils, a geological timelime and some useful pupil friendly tips for field trips. The timeline is well illustrated and has good use of colour to highlight the different periods. This is a good kids site but it is a little bit sparse in content.
