Aligned with both Texas and California education standards, this elementary science kit with manual contains classic 4th grade hands-on experiments that can be incorporated into virtually any elementary science curricula. Research confirms that hands-on science experimentation fosters deeper understanding of course materials. It offers a critical balance to any virtual courses by improving student motor skills, providing sensory feedback, and relieving screen fatigue. Each kit includes most of the materials needed for the labs (other than common household items), a manual that provides step-by-step guidance, a student journal, and a teacher’s answer key.
