3rd GradeForces and Interactions
Students hunt for a hidden magnet using different tools and the gained understanding of magnetic force! This interactive activity allows students to practice with this information before moving into a game where they can apply their knowledge!
Help Sid the Science knock down a stack of cans using science! This game tasks children with identifying surfaces that have more or less friction to slide a wood block along the floor. Flash and Java required.
- Each force acts on one particular object and has both strength and a direction. An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object. Forces that do not sum to zero can cause changes in the object’s speed or direction of motion. (Boundary: Qualitative and conceptual, but not quantitative addition of forces are used at this level.) (3-PS2-1)
- The patterns of an object’s motion in various situations can be observed and measured; when that past motion exhibits a regular pattern, future motion can be predicted from it. (Boundary: Technical terms, such as magnitude, velocity, momentum, and vector quantity, are not introduced at this level, but the concept that some quantities need both size and direction to be described is developed.) (3-PS2-2)
- Objects in contact exert forces on each other. (3-PS2-1)
- Electric, and magnetic forces between a pair of objects do not require that the objects be in contact. The sizes of the forces in each situation depend on the properties of the objects and their distances apart and, for forces between two magnets, on their orientation relative to each other. (3-PS2-3),(3-PS2-4)
Next Generation Science Standards is a multi-state effort to create new education standards that are “rich in content and practice, arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education.”
Our team from Temple University has developed this resource for all K-12 students and teachers of science. These vetted learning tools align to the NGSS. Find one we should include? Just fill out the form.
