- Mindful moment.
- Finish the questions.
- Interview partner.
- Paper notebooks. (On Thursday we will discuss and set-up your digital science notebooks.)
- What is posted in the room?
- Questions, comments, observations, ideas about the ramp-walking elephant.
- What is the sequence of events? Can we list them?
- Can we make a diagram?
- How could we make a working replica–maybe not an elephant but a device that would “walk” down a ramp?
- What are some of the critical features?
- What are some ideas about motion that might be important?
- How can we explain the phenomenon?
Let’s examine one or two phenomena involving motion–our first topic of science 7. Think of the idea that motion is change–change of position–and everything changes.
What do you notice?
- Use the paper.
- Make a sketch/make sketches. Show any details and sequences you observe.
- Describe the phenomenon in words.
- List any questions you have.
- Include your name.
- Include the following information:
- Years at AES.
- Your home country (countries-explain).
- Parents’ names and occupations.
- Best memory from your break.
- An experience from your break that involved motion. Include a description of the situation. Something you noticed. A question you had or have related to the motion experience.
- Turn in the paper at the end of our short first class. We will use what you have observed, thought, and written in our next class.
Once you receive your Ipad. Examine the follow pieces of writing and the short videos of 5 motion events.
Creative non-fiction essay on motion by a 7th grader. This student wrote an essay like this one for every week of class during his 7th grade year. Each essay was related to something related to class.
- Motion is when an object is moving. It doesn’t necessarily have to be going somewhere. When an object in motion hits another object it results in impact. The size of impact depends on the size of the objects colliding. Without motion, the universe wouldn’t be here. Nothing could ever happen without motion.
- To measure the motion of an object, I think you need the distance of travel, time of travel, velocity, force/momentum, and a relative point. You need a relative point because if an object is just moving through space, there is no point for it to move closer or farther from. If an object is just moving through nothing (open space), where it ends up later will be exactly where it ends up later will be exactly like where it started. So basically it hasn’t moved at all.
- Einstein’s theory of relativity has much to do with motion. Can time stand still if you move away from a clock/time at the speed of light? The way this works is the time travels from the clock to your eyes at the speed of light. So if you move away from the light which carries the time to you…wouldn’t time stand still? If this true, would it be possible to go back in time if you travel faster than the speed of light? The only way to find out is to try it and experiment. I doubt these experiments with time travel will occur very soon. Humans are far from travel even close to the speed of light.
- A centerfielder judging a fly ball is my specialty. My favorite sport is baseball and I know pretty well how players judge the ball. Seventy-five percent of judging is seeing the acceleration of the ball off the bat and determining if it is low or high ball. A hard, low ball would reach it’s highest point in about one second. It is quite amazing how fast the ball can accelerate into the air. I think in races, acceleration is a key part to winning. It’s a key part in motion!
Poem related to motion by a 7th grader. This student wrote a poem for every week during her 7th grade year related to something from science class.
A Tennis Ball in Space vs. A Tennis Ball on Earth
I wrote this for our unit on motion and how gravity affects our everyday life. (Note: The first line is a tennis ball in space, the second line is a tennis ball on Earth, the third line is a tennis ball in space, the fourth line is a tennis ball on Earth, etc.)
- Gliding to be free to drift wherever you please,
- Gliding in a designated path.
- Tracing your thoughts,
- Tracing the thoughts of the arm that directed you.
- Knowing you will always drift and will never end,
- Knowing you will eventually hit the ground with a thud ending all movement.
- With the whole universe to explore,
- With the whole planet to explore but not by your choices.
- Sensing the danger of a black hole,
- Sensing the danger of a playful puppy.
- Loneliness of being the only tennis ball in space,
- Loneliness of being the only thing flying.
- Being able to not feel anything for there is nothing near you,
- Being able to feel people’s hands and anything that touches you.
- Many other items that feels as strange as you,
- Many other tennis balls.
- Random and spontaneous.
- Precise and assured.
