Comparing Wood Strength

Comparing Wood Strength | Science Fair Projects | STEM Projects
Do you want to know which type of wood is the strongest? Test the strength of solid wood and plywood in this science project to find out!


The hypothesis is that the solid wood will be stronger than the plywood.

Method & Materials

You will compare the strength of solid wood and plywood by drilling a hole in each of the 12 planks, fixing them to a vice, and adding weights until the plank snaps.
You will need 4 oak wood planks, 4 redwood planks, 4 plywood planks, 40 weights, a rope, an electric drill, a ruler, a vice, and a solid table.


The results of the experiment showed that oak wood, which is a hardwood, could bear the most weight before breaking, while the plywood could bear the least before breaking.

Why do this project?

This science project is interesting because it allows us to compare the strength of different types of wood, and to see which one is the strongest.

Also Consider

Consider repeating the experiment using different widths of wooden planks to compare the results, or try repeating the experiment to include oriented strand board (OSB) and fiberboard.
