[Over 100 Years Old Lumber Company Supports Summer Vacation Free Study!] Releasing "Tree Secret Research Kit" to Learn with Real Wood

Perfect for summer vacation free study and learning as it allows you to learn both knowledge about trees and conduct experiments.

Okazaki Lumber Co., Ltd. (CEO: Kinya Hatta, hereinafter "Okazaki Lumber"), founded in 1917 (Taisho 6) with over 100 years of history, will release the "Tree Secret Research Kit," a free study and wood education material for elementary school students.

Okazaki Lumber possesses over 50,000 pieces of solid wood from 120 tree species sourced from around the world. From its vast inventory of lumber, the company has selected nine types of wood with different colors, weights, scents, and grain patterns, and commercialized them as a free study and wood education material that allows children to learn while touching real wood at home.

Amidst the decreasing opportunities for children to interact with wood, the kit was developed with the desire to "convey the charm of wood and the interest of natural materials to the next generation." By using real "solid wood" instead of colored or printed materials, children can feel the natural colors, textures, and scent differences of wood with their five senses, and learn experientially about "floating wood" and "sinking wood" experiments, as well as the specific gravity and characteristics of wood.

As a lumber company that has walked alongside wood for many years, Okazaki Lumber aims to support summer vacation free study, and by leveraging its knowledge of lumber cultivated since its founding and its leading lumber inventory in Japan, it wants to convey the charm of solid wood to children.

Furthermore, through the experience of touching real wood, the company aims to foster curiosity about familiar trees and natural materials, nurture a love for woodworking and craftsmanship, and take the first step towards choosing wood as an attractive option in their future lives.

Nine types of wood, selected from a stock of 120 species and 50,000 pieces, have been made into educational materials.

All wood pieces used as educational materials are solid wood. Children can feel the differences in color, weight, scent, and grain with their five senses, which cannot be replicated by coloring or printing, while touching them.

Additionally, the kit features the ability to compare familiar woods like cedar and cypress with species that are rarely seen in everyday life, such as ebony and bubinga. This is an educational material that allows for comparative learning of real wood, made possible by Okazaki Lumber's position as one of Japan's leading lumber holders.

The kit addresses summer vacation concerns such as "I can't decide on a free study topic" or "I'm looking for a learning material that parents and children can work on together," while providing children with an opportunity to touch real wood and learn about its charm and the interest of natural materials.

Nine types of wood, carefully selected by a lumber company with over 100 years of history, have been made into educational materials.

Will it float? Will it sink? Let's experience the specific gravity of wood.

Experience the real texture, scent, and weight.

The kit includes nine types of wood: cedar, ebony, tochi, bubinga, cypress, zelkova, oak, cherry, and paulownia. By floating the wood pieces in water, children can learn experientially about:

- The difference between floating wood and sinking wood - Why wood weighs differently - The relationship between wood's specific gravity and density By observing and comparing familiar woods to rare, famous woods, children can discover the unique differences and interesting aspects of real wood.

Write it in the workbook and summarize it as a free study project.

Rest assured with the included workbook.

The included write-in workbook clearly explains the experimental methods, observation points, hints for reflection, and characteristics of each tree species.

First, record observations and insights in the workbook, and then use that content to create a free study project on poster paper or in a notebook.

The structure is designed to be easy for children tackling free study for the first time, making it a material that parents and children can learn and work on together.

Can be used even after the experiment is finished.

Because it's solid wood, it can be enjoyed for a long time.

Many free study kits often serve their purpose only until the experiment is over.

However, this kit uses real solid wood.

After the experiment, it can be used as building blocks for play, or as a display stand for figures and small items. Furthermore, if the experiment is conducted again in later school years, increased knowledge may lead to new discoveries.

This kit's feature is that it allows you to continue to be in contact with the charm of wood for a long time, rather than being a "use it once and it's over" product.

Comments from the person in charge

The starting point for developing this kit was the desire to convey to children the interesting differences and individual characteristics of trees that we feel when working with wood. Please experience the unique qualities of real wood that cannot be conveyed through picture books or photos alone.

Through this experience, we hope to foster curiosity about familiar trees and nature, encouraging questions like "Why?" and "I want to know more," as well as an understanding of the joy of making things and the charm of wood.
