![]() ![]() Model, you will need about 300g of gray clay and one half box of the (4-color) Students work in pairs and each student gets to keep one half of the 3-D Earth Additional colored clay (a 450g boxĬontaining four colors - green, yellow, red, blue - and costing $2) was “stores” supply (or a craft store) for about $2/kg for the estimating activityĪnd for the mantle “layer” of the final 3-D model. We have used about 300g of gray modeling clay obtained from the university Volumes of different colors of the modeling clay to correspond to the relative Materials is necessary and working with the modeling clay does not make aĬlay are higher cost and greater difficulty in performing the “estimating” and More accurate, including nearly spherical layers and sharp boundaries between Using the modeling clay has the following Spherical and the boundaries between layers are reasonably sharp. To make an Earth model with the baker’s clay in which the layers are reasonably The baker’s clay and the mixing of food coloring are “messy” activities,Įspecially for students. The baker’s clay is easy to work with and results in a model Earth that, whenīaked is relatively permanent and “rugged.” 3) The “estimating” and “dividing” activities are easier to perform with The baker’s clay option has the following Materials used to make the 3-D models are described. Opportunity for some practice in problem solving and math skills. To enhance visualization and illustration of the relative volumes of Earth’s In the Earth’s Interior Structure activity** by utilizing a 3-dimensional model This project reinforces the concepts included Regions - inner core, outer core, mantle and crust.
