This is the grading rubric for lab planning sheets. The conclusion (RAPPIN) is described below.
Full Credit 4 points 3 points Below 3 pts.
RAPPIN: R: Restate question and hypothesis A: Answer question and indicate whether or not your hypothesis was proven or disproved. P/P: Include the data to support your lab results. I: How could the experiment be improved? N: What new science question would carry the inquiry further?
Requirements for thunderstorm paper:

Human Body Systems Story Assessment:
Waking up, Eating Breakfast and Walking to School (A Fascinating Tale of Biological Systems)
“Buzzzzz,” my alarm sounded. I leapt out of bed and ran to the kitchen table. * My mom had made my favorite breakfast: dehydrated eggs, year-old marshmallows and dry potato bud flakes! Yum… I ate * quickly because I was looking forward to finishing my science homework. On the way to school, a bee landed on my arm and stung me. * The bee sting shocked me so badly that I tripped on a large rock, scraped my knee and screamed, “Loser!” at the bee. * I finished the walk to school but was exhausted. I fell asleep during first period (math). * At least I didn’t sleep through anything exciting like science.
This is a 50 point assessment and is due . Your assignment is to insert the real story where you see a *. The real story is how our biological systems work together when each event occurs. Your description will include the systems, the organs, cells and/or molecules within the systems and how they help your body respond to each action. You will also want to include information about how each system works with others. For example, you will want to include the circulatory system if you describe the immune system. The grading rubric on the back of this page will help your story completion.
Systems include: · Respiratory · Circulatory · Immune · Digestive · Skeletal · Muscular · Nervous
Resources: class notes from system readings, answers to action statements, on-line research (shouldn’t be needed if your notes are complete)
Note: Class will be held in the main library computer lab on Tuesday, March 31, and Wednesday, April 1, to complete the typing portion of this assignment. If you cannot finish typing in the computer lab, please bring a flash drive so you complete this at home.
Final Project: Simple Machines Your challenge is to design and build a machine that will launch a ping-pong ball into a bucket that is one meter away. The bucket is 22 cm. in diameter and 18 cm high and located directly in front of your machine on the same plane. Your project will include energy transfer diagrams and 4-5 paragraphs describing the motion, energy transfers and at least two energy transformations. Each table group will submit one machine.
1. Project Proposal Due: May 25 · Overall plan to accomplish the task · Explain each of your steps. (Example) o Step 1: Release a ball onto an inclined plane o Step 2: Ball rolls down the inclined plane and drops into a bucket. o Step 3: Bucket that is attached to a rope and pulley descends resulting in the lifting of a latch. o Etc. · Be sure you identify your four simple machines within your 4-5 steps. · Incorporate at least 2 energy transformations (not transfers) in your steps.
2. Drawing Due May 27 (top and side views) At this point, you should be experimenting with a physical model of your final design. · Prototype Report Due o Identify each of your 4-5 steps o Describe in full sentences, the interactions that take place at each step. o Use energy diagrams to describe the transfer of energy. o Identify potential and kinetic energy locations. o Draw a force diagram at each of two locations of your choice. o Describe any motion involved. (Constant speed, acceleration, etc.) ? o Identify the simple machines involved. o List Materials used o Include preliminary sketches. Number each interaction to correspond with your descriptive paragraph and energy diagram.
4. Final Project – Bring to school June 10. · Your machine must not take up a space larger than 4 sq. feet (2’x2’). · Your machine must accomplish the task in four to five steps - no more, and no fewer. · Only one applied force to initiate the process is allowed. · Your machine must not incorporate any pyrotechnics. (No explosions, please) · Your machine must have a name and a slogan. · Your names and class periods must be on your machines.
5. Have fun and learn a lot!
