A three part 1500+ PowerPoint slideshow from www.sciencepowerpoint.com becomes the roadmap for an interactive and amazing science experience that includes a bundled homework package, answer keys, unit notes, video links, review games, built-in quizzes and hands-on activities, worksheets, rubrics, games, and much more. Also included are instruction to create a student version of the unit that is much like the teachers but missing the answer keys, quizzes, PowerPoint review games, hidden box challenges, owl, and surprises meant for the classroom. This is a great resource to distribute to your students and support professionals. Text for the unit PowerPoint is presented in large print (32 font) and is placed at the top of each slide so it can seen and read from all angles of a classroom. A shade technique, as well as color coded text helps to increase student focus and allows teacher to control the pace of the lesson. Also included is a 12 page assessment / bundled homework that chronologically follows the slideshow for nightly homework and the end of the unit assessment, as well as a 8 page modified assessment. 9 pages of class notes with images are also included for students who require assistance, as well as answer keys to both of the assessments for support professionals, teachers, and homeschool parents. Many video links are provided and a slide within the slideshow cues teacher / parent when the videos are most relevant to play. Video shorts usually range from 2-7 minutes and are included in organized folders. Two PowerPoint Review games are included. Answers to the PowerPoint Review Games are provided in PowerPoint form so students can self-assess. Lastly, several class games such as guess the hidden picture beneath the boxes, and the find the hidden owl somewhere within the slideshow are provided. Difficulty rating of 8 (Ten is most difficult). Areas of Focus: -Newton's First Law, Inertia, Friction, Four Types of Friction, Negatives and Positives of Friction, Newton's Third Law, Newton's Second Law, Potential Energy, Kinetic Energy, Mechanical Energy, Forms of Potential to Kinetic Energy, Speed, Velocity, Acceleration, Deceleration, Momentum, Work, Machines (Joules), Catapults, Trajectory, Force, Simple Machines, Pulley / (MA Mechanical Advantage), Lever /(MA),Wedge /(MA), Wheel and Axle (MA), Inclined Plane / (MA), Screw /(MA). This unit aligns with the Next Generation Science Standards and with Common Core Standards for ELA and Literacy for Science and Technical Subjects.

– The pulley moved along the rope very easily.
We were able to move the load easily once it
was lifted. The pulley rolled down the rope
because of it’s potential energy.
• Not very good for lifting.
