Science

 

 

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.
