Gravel - 20kg

When is a stone not just a stone? When it is a catalyst for complex water flow investigation! This 20kg bag of gravel is an incredibly versatile natural material, moving children far beyond simple sand and water play. Use it to construct miniature landscapes, build dams and barriers in a dry creek bed, or fill up wheelbarrows for purposeful physical transport. The satisfying sound and varied texture offer rich sensory feedback, supporting focused attention and sensory processing. Gravel is brilliant for science, enabling children to observe how water flows and how materials displace it. It is also a fundamental resource for building gross motor strength as children scoop, lift, and pour the heavy medium. A robust, open ended resource that connects children directly with geological materials and engineering concepts.

Features

• Heavy 20kg Bag: Provides a substantial quantity suitable for large scale ground covering or deep sensory tray filling.
• Natural Small Grade Gravel (~6mm): Offers varied, interesting tactile sensory input compared to uniform sand.
• Excellent Drainage Medium: Ideal for demonstrating concepts of permeability and water runoff in environmental science projects.
• Durable, Non Organic Material: Will not decompose or require frequent replacement, ensuring long term, cost effective provision.
• Versatile Density: Perfect for exploring concepts of weight, mass, and volume when used in conjunction with containers and balances.

Benefits

• Physical Development (PD): Strengthening gross motor skills through scooping, lifting, wheelbarrow transport, and controlled pouring of the heavy material.
• Understanding the World (UTW): Promotes scientific thinking regarding water flow, erosion, density, and the composition of natural landscapes.
• Mathematics (M): Supports practical play of capacity, volume, estimation, and weight through sensory measurement tasks.
• Sensory play (SE): Provides rich auditory (clinking) and tactile input, supporting children's sensory processing and focus.
• Design and Technology (DT): Encourages engineering principles when children use the gravel to build pathways or manipulate water channels.
