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
Finally, we will study how the eye works. Of course, we will observe
an actual sheep eye dissection for a realistic experience.
