Learn how levers are used to increase a force for lifting heavy objects and how they can change the direction of motion. Find out how you can create models with complex motion by connecting many levers together and learn how these linkages can be applied to various machines. Build 16 working models such as a seesaw, a movable weight scale, a wheelbarrow, a parking gate, a toy with moving figures, a pantograph and two types of linkages. You can find easy-to-follow building instructions for all models either online or in the booklet included. The booklet provides detailed explanations of the different scientific principles applied and incorporates innovative experimental activities for hands-on learning. A Quiz section is also available to challenge your newly acquired knowledge. Suits ages 9 years +.
