Head over to STEM Inventions for a whole host of exciting projects which can be constructed at home, such as the marble roller coaster! Most of the ideas use bits and pieces from around the house, or can easily be adapted to use materials you can find. Although each of the projects has an activity sheet with detailed guidelines, I like the open-ended nature of the activities and they also have ‘tips and troubleshooting’ notes. Clicking on the ‘Science Fair Experimental Guide’ symbol even gives a suggested science investigation linked to the activity, with steps for an experiment older children could follow.
