Van Helmont conducted an experiment where he planted a willow tree in soil contained in a pot and observed it grow over 5 years watered only with rainwater. He found that the tree gained 164 pounds in mass while the soil only lost 2 ounces. He concluded that the water was the sole source of the tree's growth. However, the experiment did not account for contributions from minerals in the soil, gases in the air like carbon dioxide, or the role of sunlight in photosynthesis. More controlled experiments are needed to fully understand plant growth.
This document promotes activities and camps at the National Jamboree, including whitewater rafting, archery, zip lining, swimming, paddle boarding, and skateboarding at the #1 ranked skate park in the world called The Summit. It also mentions staff and participant shows, setting up camps and facilities, and a trip to Washington D.C. to visit landmarks before the 2017 National Jamboree.

This document discusses the design and safety of Nissan's LEAF electric vehicle battery system. It includes the following key points:
1. It provides an overview of Nissan's lithium-ion battery development history and the specifications of the LEAF battery which uses laminated lithium-ion cells.
2. The battery, module, and pack design focuses on safety, reliability, cooling and durability including mechanical supports and thermal management.
3. Safety elements of the high voltage system include failsafe controls, crash detection systems and triple protection structures to prevent electrical leakage and damage to the battery during a collision.
The document provides details on the new fourth generation Prius hybrid vehicle. Some key points:
- The new Prius was developed with goals of impressive fuel efficiency, eye-catching design, fun driving performance, and social responsibility.
- It features an advanced new hybrid system with a highly efficient engine and compact, high-performance lithium-ion or nickel-metal hydride battery. This results in a target fuel consumption of 40 km/L.
- Use of the Toyota New Global Architecture allows for a lower center of gravity, increased rigidity, and a more comfortable ride while maintaining excellent handling.
