This week's slideshow highlights: 6th graders exploring the history of Earth by setting up a human timeline of important geologic events and how they impacted the rise and fall of life on Earth going back to at least 3.5 billion years ago; 6th graders selecting from a drawing new class helper positions as Decatur JHS students like to help out and take more ownership in our Science classroom; 7th graders exploring natural selection and evolution (see video below); and 8th graders began inquiry investigations into "Energy Transformations" by rotating to various hands-on stations to explore how energy and matter interact and transform such as: solar energy to electric and then mechanical; chemical energy to thermal; chemical energy to electrical and then mechanical/kinetic; etc. Thank you for stopping in this week:)
