From Hand Tools to Robots in Factories

In the early 1900s, many products were made with hand tools. Skilled workers built items piece by piece, and production was often slow, but workers could customize what they made.

By the mid-1900s, assembly lines became common. Instead of one person building an entire product, each worker completed a small task as the item moved along the line. This increased speed and lowered costs.

In the late 1900s and into the 2000s, factories began using more computers and robots. Machines could repeat precise movements and work in environments that might be unsafe for people.

Today, many factories use a mix of human workers and automation. Training now often includes technology skills, showing how manufacturing has continued to change over time.

Layers of a Rainforest

Rainforests are organized into layers, and each layer has different light, temperature, and living things.

The emergent layer is the highest. A few very tall trees rise above the rest, catching strong sunlight and wind. Birds and insects often use this layer to travel and hunt.

Below it is the canopy, a thick “roof” formed by treetops. Many fruits and leaves grow here, so monkeys, sloths, and colorful birds find food and shelter in the canopy.

The understory sits beneath the canopy and receives much less light. Plants here often have large leaves to capture sunlight. Many insects and amphibians live in this humid, shaded space.

Finally, the forest floor is the darkest layer. Fallen leaves break down quickly, returning nutrients to the soil.
