Reflecting on Diffraction
Source Institutions
With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.
Amazing Air
Source Institutions
In this activity, learners construct a small "air cannon," and use its airflow to put out a candle (lit with the help of an adult).
Let It Roll
Source Institutions
In this activity, learners will make their own "ball bearing" with two jar lids, marbles, and some household supplies.
Sink or Float
Source Institutions
In this activity, learners will make predictions and experiment with different objects to see if they sink or float.
Crazy Camouflage
Source Institutions
In this activity about camouflage, learners create a model that shows how a flounder is able to blend into a variety of environments.
Rubberband Rockets
Source Institutions
This fun and simple activity is a rubberband rocket design challenge! Learners will explore how tail fins can help to stabilize a flying object, while also exploring potential and kinetic energy.
Drag: Parachute from the Stratosphere
Source Institutions
This is an online game recreating the longest ever (at that point in time) freefall jump by Air Force Captain Joe Kittinger.
Crazy About Kites
Source Institutions
In this activity, learners build a kite out of paper, change it, and try to make it fly even better. With their new knowledge of kite making, students can then go on to create their own kite designs.
Flinker
Source Institutions
In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.
Conveyor Engineering
Source Institutions
In this activity, learners explore the engineering behind the conveyor belt and consider the impact this invention has had on transportation and the coordinated shipping and delivery of goods.
Take Me to the (Magnet) Races
Source Institutions
In this activity about magnetism (page 11 of the pdf), learners will experiment with magnets to explore how opposite poles attract and similar poles repel in magnetism.
Spinning Your (Color) Wheels
Source Institutions
In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.
Spool Racer
Source Institutions
In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.
Make a Water Cycle Wristband
Source Institutions
In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.
Lift Experiment
Source Institutions
In this experiment, learners investigate how the size of a wing affects lift. Learners count the number of pennies an egg crate plane wing can hold until the plane will no longer fly.
Minibot
Source Institutions
In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
Sticky Situation
Source Institutions
In this activity, learners separate the protein from milk and and use it to make their own glue.
Paper Whites
Source Institutions
Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.
Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
Keep it Cool
Source Institutions
In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
