Students will be introduced to the concept of pigment chromatography and will collaborate to perform an inquiry in which they will separate plant pigments using paper chromatography.
Students will use a CD Case Seed Viewer to observe how seedlings respond to Earth's gravity and then create systems to mimic a low gravity environment, such as on the International Space Station.
Students will be introduced to the leaf structures of dicots and their role in gas exchange. Students will collaborate to perform an inquiry in which they follow a simple procedure to collect leaf cells samples and compare leaf structures from different plants.
Learn the basics about Paper and Thin Layer Chromatography. What is Chromatography and why is it done?
Learn about types of plant tropism - phototropism, geotropism and thigmotropism.
Discover the hormones that dictate whether a plant grows downwards with gravity, towards water and nutrients, or upwards towards light.
Astronauts traveling to Mars will need to grow some of their own food in order to survive and stay healthy. But on Mars will there be enough light to meet the needs of growing plants?
Air is made up of nitrogen (78%) and oxygen (21%) with small amounts of other gases such as argon and carbon dioxide. It probably then comes as no surprise that nitrogen is important for all organisms as it helps them to live and grow.
Most people do not think twice about soil, but we could not live without it. The plants we eat, and the plants that feed the animals we eat, depend on soil. Plant roots need soil for physical support. Plants also get nutrients from soil, which they need for healthy growth and development. Future astronauts on a long-term mission to Mars will want to grow some food crops to add to their diet of packaged food.
This video describes how vertical farming works to provide the needs of growing plants. The pros and cons of vertical farming are also highlighted.
This video by It's Okay to be Smart, describes the effects of the space environment on the human body.
The Seeds of Knowledge learning strategy offers students a process to practice the skill of making connections by connecting their prior knowledge and learning experiences from previous grades to a new inquiry opportunity, such as the Tomatosphere™ Seed Investigation.
The Making Connections Organizer learning strategy uses a graphic organizer to help students connect science inquiries to their prior knowledge and experiences, prior inquires and the world at large.
The skill of questioning allows students to pursue their ideas and explore the world around them. Being able to ask rich questions about who, what, where, when, why, and how, enables students to construct their knowledge and develop an understanding of concepts and experiences.
The Testable Questions Toss-up learning strategy offers students a process to generate and practice writing testable questions that may be applied to conducting fair tests within an inquiry investigation.
