REACTION RATES - NASA

National Aeronautics and Space Administration REACTION RATES NASA SUMMER OF INNOVATION UNIT Physical Science GRADE LEVELS 4 6 CONNECTION TO CURRICULUM Science TEACHER PREPARATION TIME 10 minutes LESSON TIME NEEDED 1 hour Complexity: Basic LESSON DESCRIPTION A whole antacid tablet and a crushed tablet are added to separate beakers of water so that their relative REACTION RATES can be compared. OBJECTIVES Students will Discover conditions that make a REACTION proceed faster or slower Demonstrate how increasing the surface area of a chemical increases its REACTION rate NATIONAL STANDARDS National Science Education Standards (NSTA) Physical Science Properties and changes in properties of matter Science and Technology Abilities of technological design Understanding science and technology MANAGEMENT This activity is an ideal way for safely showing how the burning rate of rocket propellants is increased without having the students use fire.
