Liz Dilts on 16 Feb 122.1.3. Predict and experiment with methods (e.g. sieving, evaporation) to separate solids and liquids based on their physical properties.2.1.4 Observe, sketch, demonstrate and compare how objects can move in different ways (e.g., straight, zig-zag, back-and-forth, rolling, fast and slow).2.1.5 Describe the position or motion of an object relative to a point of reference (e.g., background, another object).2.1.6 Observe, demonstrate, sketch and compare how applied force (i.e., push or pull) changes the motion of objects. Differentiation: Instead of writing out a hypothesis, have special education students draw the designs or what they predict will happen to the salt when they swing their pendulum.

Using paper, string, and salt, students will create a cone out of the paper that will act as their pendulum. They will swing the pendulum so it just touches the pile of salt and watch the designs it makes. Students can change the pendulum's direction to see if that changes the design.
