Students grow, draw, measure and eat plants and plant parts.
Students experiment with plants to answer the questions of why plants need light and what they do to survive when they don't get enough. They learn about the chemical processes that take place in every cell to extract stored energy from foods and to build new body materials. To decide on what changes to make, students consider the properties of materials that make them useful, through simple experiments and research. Students look closely at the everyday household technology of humidifiers, dehumidifiers, hair dryers, and clothes dryers to understand the changes of state from liquid water to gaseous water vapor and back. Energy considerations are also explored at a basic level.
