3-2-1 Blast Off Understanding Reaction Rate to Better Design a Toy Rocket!
This lesson was developed to align with the three dimensions of the Next Generation Science Standards (NGSS), specifically through the engagement of students by using science and engineering practices (SEPs) and applying the crosscutting concepts (CCCs) to understand the disciplinary core ideas (DCIs). Understanding reaction rate is a foundational chemistry concept and is used as the anchor phenomenon for this lesson. Reaction rate is outlined in NGSS Performance Expectation, HS-PS1-5
The objective of this lesson is for students to be able to construct a definition of reaction rate and argue from evidence why they have designed the “optimal” rocket, through the CER (Claim, Evidence, Reasoning) writing method. In the lesson, students will work to understand reaction rate through the analysis of a toy’s design, the Alka Seltzer rocket. They will work through the NGSS engineering practices to determine the optimal rocket based on their understanding of changing concentration, temperature, and reaction rate. Students will model the reaction in their rocket on a macroscopic and microscopic level, and better understand what conditions make the best rocket.
Teachers are given the option of having students build and test their own Alka Seltzer rockets. However, this is not absolutely necessary for the lesson and could not be completed within the time frame of a 50-minute class. Yet such an an activity after the lesson would make the learning more meaningful and engaging for students! Instructions for building Alka Seltzer rockets can be found below in the "Additional Online Resources" section.
Prerequisites include an understanding of the CER writing method, and a familiarity with modeling. This lesson will take one 50-minute class period to complete. Supplies needed are: the student worksheet. Optional supplies: Film canisters, Alka Seltzer and Water (for students to create their own alka seltzer rocket). During classroom breaks, there will be modeling activities, small group and whole group discussions, and writing activities.

The wind is lifting the sail not pushing it.
This was amazing👏👏👏👏

You should explain what a "moment" is. Not everyone has a degree in mechanical engineering.
Thank you for this presentation ❤
Has any one ever seen an experiment proving the hypothesis that air destined to travel over the top of a foil increases its speed when it encounters the leading edge of the foil and begins its longer trip over the top? One could add two pulses of dye into a slip stream so that they travel on either side of a foil. The expected result, according to the explanation of lift in this video, should be the pulses arriving at the trailing edge in exactly the same relation that they arrived at the leading edge despite one pulse having to travel a longer distance. The pulse had to have received a force in the trailing edge direction to increase the speed component of the velocity. What generated the force int he trailing edge direction that increased the speed of the pulse that went the longer distance?
Interesting activity, thanks for posting

Have you also investigated regarding LWL over the Hull Speed as yet conceptualising the boatbuilding with short LOD with wide Beam but all of my hull concept obtained semi displacements hull as enough to configurate proper ballasting systems using Gaff Rigs as main sail as yet I mention a pocket yacht with 16 or 17' LOD under the 20 or 21 LOA as though I was not properly schooled with degree but technically under the domestic doctrine standards nobody believe me with extra-curricular property especially within these curriculum aren't been part a standard curriculum here, as fell short some degree of misunderstanding enough to call me a delus
Excellent resource and a good introduction to the topic ❤
All i heard was words. I i kinda get it. Im knowledgeable with planes and helicopters and understand them easily but i just can't grasp sail boats.
why even bother assigning a dollar value to the production of ATP within a human body?
I understood sailing dynamics better from this czcams.com/video/FCcKeOmYHFY/video.html childish video, than from the MIT engineering professor here. Cheers
You linear momentum explanation is ignoring friction. And if either of the balls spin, that affects the friction even more. And some of the energy is transferred into the sound so there are other factors at play.
thanks for talking about the physics of pool. I am interested in continuing this disscussion.
How long would DNA last on a piece of clothing. I am looking at a sixty year old murder. The clothing of the person was stripped off during the murder but perhaps something would still exist on the trheads.
the teacher assumes that the student knows what she's talking about without pointing to. She leaves the exercises with insufficient context to come to conclusions... she never took teaching classes

Why mole has a unit mol when it is a pure number like dozen? 🤔
Mole doesn't has its unit as mole.Mole itself is a SI unit of amount of substance(n). However,mole is represented by mol,i.e,mole's symbol is mol.Just like kilogram having its symbol as kg.
Hope it helps you!

this is over any newbie's head just go find a sailing school and learn hands on it's too easy to over think sailing
Thanks , very informative video
I dont watch sailboat races I participate in them
99 . 7 percent of the population is enjoying nuclear technology halogenated vinyl and halogenated carbon erosion of atmosphere and fertility globally.
So the downwind quarter is the fastest quarters to sail.below 90 degrees to the wind. 2.0 times windspeed is maximum boat speed. But perfection is not a realistic goal. Vesta's speed can be reached in a full size sailboat design of normal academic design. If the keeling design is correct and the width is twice the height of the mast or greater.
The fastest direction is across the wind. The apparent wind ahead of the boat ends the speed of the boat.
The stem is the most important design quality of a sailboat design. Ballast the boat and keel the sails.
The stem is halfway between the mast and forestay of the largest sail. This is the point where keeling of the headsails begin and should relative to the sail area ratio of mainsail and headsails.
Lateral resistance ahead of the sail effort is essential. Mast and stem lateral resistance is essential to rudder control and lift.
The sailboat can sail up to twice the speed of the wind but this is theoretically perfect number and not physically possible. 1.5 times the windspeed is a realistic goal but without stem to stern academic keeling design this ambition can't be seen.
The center board should be directly below the mast and ahead of the mass. If you keel the boom the boat heels over before moving forward and has less sail power..
The keeling of the mast at the mast is often missing.
The mast should be keeled and the headsails keeled more deeply between the mast and forestay.
What is usually missing from sailboat design today is keeling design that has lateral resistance ahead of sail effort. The stem to stern academic keeling design reduces heeling over and increases speed of the sail boat. Most importantly this keeling design keeps the boat easily sailing into the wind and the sailor can easily keep the bow to waves and wind. This lateral resistance ahead of the sail area is essential to create lift and have greater speed.
Oh .. I dont get it. Bernoli or whatever air thing is never makes sense It cant generate enough lift to lift a 300 70kg adults and fuel and avionics right ? .. along with its own weight. .. the perpendi doesnr make sense
Good explanation ❤❤❤❤
thanks for the woderfull video.
I wonder how such a well designed system can creat it self by chance !!!!! it is hard for an engineer to buy.. it also goes against all enthropy and propabilities theories.
How does this work if there's a discord in all cells of the body? Like being coeliac or having a propensity to colon cancer due to genetics?
Utterly fantastic!
That's why i like youtube
