Third graders will soon understand the difference between physical and chemical changes. We will combine vinegar and baking soda with explosive results! Students will learn that a chemical change is a result of combining substances with a reaction and the formation of new matter: CO2! We will also watch a chemcial change when we combine coke and mentos: More CO2! Students will learn that there are many types of energy on earth: heat, light, electricity, wind, water,and batteries. They will perform labs to help them understand that energy can be stored. They'll also learn that twisted rubber bands have potential energy until they are released. Upon unwinding, they exhibit kinetic energy. Students will understand that heat, light and sound energy travels in waves and that electricity travels in wires. The class will then focus on life science. We will use real plants to explore plant parts and their functions. We will soon perform labs to observe actual seed germination and perform flower dissections. Finally, we will study how the eye works. Of course, we will observe an actual sheep eye dissection for a realistic experience. Ms. Armstrong
