Why are HOS classes grouped according to age and grade level?

Children’s motor skills and understanding of concepts go through various stages of development.  Instruction should be age appropriate for manipulating materials and building on what the children already know.

Why do the HOS programs include a mix of activities (model building, songs, games focused observations and experiments) and simple materials that can be manipulated and taken home?

Children learn by testing ideas, building models, observing carefully and making decisions based on experiments.  The fun and variety of HOS activities are different from school activities. 

Why do the HOS programs provide each child with materials to take home?

Family involvement is stimulated when children show parents what they have learned in the HOS classes.  The take-home activity also encourages children to take ownership of their learning.

Why do the activity guides include carefully constructed questions for Adult Leaders to ask during the sessions?

Children develop critical thinking skills when a knowledgeable adult asks questions that stimulate ideas and respect the child’s ability to think.

Why are HOS classes limited to no more than fourteen children?

A small class size provides more opportunities for children to ask questions and express themselves. 

Why doesn’t the HOS program include tests and grades?

Children can develop a better appreciation for science in a fun-filled learning environment without the pressure of formal tests and grades.
