technology background

It is true—engineering may be enjoyable for learners of all ages, skills, and grade ranges. Nonetheless, like many different disciplines, engineering is commonly finest realized via expertise. This text gives three hands-on engineering classes that permit pupils of all ages and skill ranges to expertise science ideas, reminiscent of potential and kinetic vitality, gravity, friction, and Newton’s Legal guidelines of Movement. The entire unique classes got here from NASA’s summer season schooling alternatives, however the procedures have been tailored to suit the wants of particular schooling college students in grades 7-10. Seek advice from the unique lesson plans for lists of supplies wanted.

A Safer Area Capsule

Predominant Ideas: Switch of vitality, movement and drive, scientific design, and the properties of objects and supplies.

The Lesson: Mix parts from two NASA actions: the Landing Problem and the Mars Pathfinder Egg Drop Problem. Learners design and construct a shock-absorbing system that can defend an astronaut when he lands utilizing foam, marshmallows, bubble wrap, cotton balls, and cardboard. Your scientists consider and enhance their design based mostly on testing outcomes. Relying on the dimensions and skill of the category, it’s possible you’ll both select to construct a bunch construction or break into small teams.

To seize everybody’s consideration, place a uncooked egg right into a plastic cup and inform the category that that is the house capsule containing astronauts. Ask them to consider why it will be important for the house capsule to land as gently as doable. Then drop the cup (right into a bucket if you don’t need a large number). Ask your class to foretell what has occurred to the egg. After discussing why the egg broke, current the problem: design a construction that can defend the astronauts and the house capsule upon touchdown.


  1. Pupils will discover totally different supplies that soak up shock effectively. Supplies to offer embody: mini marshmallows, cotton balls, bubble wrap, and foam packing peanuts. Drop further eggs right into a container padded with every of those supplies and permit your younger engineers to watch the outcomes. They need to choose one to make use of. 
  1. Drop a second plastic cup, empty this time, and have the category observe what occurs to it because it falls. Does it tip over? How can tipping be prevented? Give the instance of a bicycle versus a automotive; a pencil versus a fats marker. Why does one tip over and the opposite doesn’t? Lead college students to see {that a} wider base prevents tipping. Present them tips on how to connect a cardboard platform to the cup with tape. Landing Problem contains further notes on the dimensions of the platform.
  1. Ask pupils the place the shock absorbing materials ought to go to guard the house capsule. In the event that they wish to place it contained in the cup, remind them that there shall be gear contained in the capsule so the shock absorbers should be exterior the capsule. It is also essential to guard the capsule from injury in order that the astronauts can return to Earth when the mission is full. Exhibit tips on how to place the shock absorbers on the underside of the cardboard base platform. Sandwich the shock absorbers between a second piece of cardboard the identical measurement as the primary.
  1. Have children observe dropping their shock-absorbing buildings and eggs whereas making observations about tipping and injury to the egg. Encourage all teams to make modifications to their designs and retest.

One of many extension concepts recommended videotaping the drops after which breaking the movies into half-second frames so that everybody can clearly see the small print of the autumn.

Balloon Rocketry

Predominant Ideas: Potential and kinetic vitality, measurement, and the scientific course of.

The Lesson: Use parts from NASA’s Heavy Lifting Air Engines exercise. College students observe how unequal stress creates energy and so they assemble balloon-powered rockets to launch the best payload doable to the classroom ceiling.

To focus the category’s consideration, watch a video of a rocket launch in order that they will witness how a rocket strikes in the wrong way of the drive propelling it. Focus on how stress builds up contained in the rocket and is then launched to energy the rocket upward.  


  1. Blow up a balloon and tie it shut. Ask pupils to watch if the balloon will transfer by itself. Focus on how the rocket engine shops potential vitality just like the balloon. When that vitality is launched, it turns to kinetic vitality and the rocket will transfer.
  1. Blow up a second balloon and pinch it shut. Ask your scientists what’s going to occur in the event you let the balloon go. After just a few responses, launch it. Lead a dialogue about unequal stress: the air stress contained in the balloon is larger than the stress within the room. Different acquainted examples of this idea may be pushing a basketball down in a swimming pool after which watching it lurch to the floor, or shaking up a soda can simply earlier than opening it. When stress builds, it has the facility to maneuver objects.
  1. Distribute straws and balloons. Inform individuals that the straw is the rocket and the balloon is the engine. Exhibit tips on how to connect the straw to the balloon with tape. Some people might have a balloon pump to get their balloon inflated. Carry the inflated balloons to the launch pad—a string tied between two desks. Enable individuals to launch their rockets, measuring how far they go and recording the outcomes. What accounts for variations between distances? After a few launches, the balloons will stretch out and have to be changed. College students can examine the impact that totally different balloon shapes and sizes have on distance. After everybody has had a few probabilities to watch how far the balloons transfer horizontally, swap to a vertical launch pad by attaching the string to the ceiling. You may as well connect paperclips to the straw to analyze how weight modifications the quantity of vitality wanted to maneuver the rocket.

A Higher Moon Rover

Predominant Ideas: Friction, Newton’s 2nd legislation, potential and kinetic vitality, measurement, and scientific design. 

The Lesson: Primarily based on the NASA Roving on the Moon exercise. Youngsters construct a rover out of cardboard. They use rubber bands to spin the wheels and enhance the designed system based mostly on testing outcomes. Relying on the dimensions and skill of the category, it’s possible you’ll construct a bunch construction or break into small teams.

Earlier than presenting the lesson, go to the web site for a listing of supplies the category will want and for directions on constructing a prototype. Construct the mannequin as instructed and precut the components for every group to construct a rover. To save lots of time, you may select to preassemble a portion of the rovers relying on the power ranges of your individuals. Reduce out tires in quite a lot of shapes to switch the sq. ones. Some shapes you’ll ant to attempt to embody are octagons, circles, triangles, and ovals.

To begin off the lesson, show this picture of the moon rover. Ask younger scientists to determine options that evaluate to vehicles used on Earth. Some solutions may embody chassis, wheels, fenders, motor, seats, seat belts, antenna, battery, digicam, and steering controls. Clarify that the moon rover required particular tires that will work with out an environment, might stand up to excessive temperatures, wouldn’t get caught in quite a lot of terrains, and wouldn’t clog with moon mud. Present the category your moon rover prototype and ask them to determine every half’s perform. Level out that sq. wheels will permit the rover to dig into mushy surfaces reminiscent of sand. Exhibit how turning the rear wheels winds the rubber band to construct potential vitality.


  1. Assist people or teams assemble their rovers. Youngsters ought to have the chance to fastidiously wind and launch their rovers a number of occasions to achieve understanding of how the potential vitality is transformed to kinetic vitality to show the wheels.
  1. Pupils ought to rely the variety of occasions they wind the rubber band after which measure how far the rover strikes. Plot the outcomes on a graph. Repeat this on totally different surfaces reminiscent of tile, carpet, and a sheet. Draw everybody collectively to match the outcomes.
  1. Enable teams to trade their sq. wheels for a distinct form. Repeat the experiment by winding and releasing the rovers on numerous surfaces. Focus on how the totally different formed wheels affected the efficiency.

Further Modified Classes:

Though easy, these classes will reinforce scientific ideas and provides your learners real-world observe with science and engineering. For extra particular schooling classes, try these sources on Lesson Planet.

Circle Multiplication: 7s and 8s

Methods to grasp multiplication info are essential for all youngsters. This concept employs a tactile exercise and repetition to make info actually “stick.”

Taking part in with Science

I favored this lesson for its means to have interaction children with science in acquainted toys just like the Hula-Hoop, slinkies, spring-action vehicles, and spinning tops. Teams observe a toy, determine the science behind it and performance of the components, and make a poster illustrating their discoveries. Simply tailored to suit a wide-range of learners.

Arms-On Outlining

A language arts lesson on outlining that requires motion, which appeals to most kids. Members type sentence strips a couple of matter to see how headings and particulars match collectively to make paragraphs. I like this for particular schooling pupils in grades 5-8.
