Cellular respiration is the process by which our bodies convert glucose from food into energy in the form of ATP (adenosine triphosphate). Start by exploring the ATP molecule in 3D, then use molecular models to take a step-by-step tour of the chemical reactants and products in the complex biological processes of glycolysis, the Krebs cycle, the Electron Transport Chain, and ATP synthesis. Follow atoms as they rearrange and become parts of other molecules and witness the production of high-energy ATP molecules.
This activity can be used as an extension for unit over macromolecules or an application of the metabolism unit. The purpose behind this activitity is to really look at the foods and drinks we used to obtain energy and see of they do what they claim to do. The circle of viewpoints activity is built around generating a list of ideas/perspectives about a given topic and then using that information for a prompt to dive deeper into the topic. This activity is built in in 3 parts Background reading and brainstormingQuestions and Reserch Socratic Circle
What happens when an excited atom emits a photon? What can we deduce about that atom based on the photons it can emit? A series of interactive models allows you to examine how the energy levels the electrons of an atom occupy affect the types of photons that can be emitted. Use a digital spectrometer to record which wavelengths certain atoms will emit, and then use this knowledge to compare and identify types of atoms. Students will be abe to:
