Urine the Know
Source Institutions
In this activity on page 5 of the PDF, learners compare water with artificial urine to see how urinalysis works. Learners use urinalysis test strips to test for glucose and protein in the fake urine.
Invisible Sunblock
Source Institutions
This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.
Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.
Yogurt Cup Speakers
Source Institutions
Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.
A Simply Fruity DNA Extraction
Source Institutions
In this activity, learners extract DNA from a strawberry and discover that DNA is in the food they eat.
Paper Airplanes
Source Institutions
In this activity, learners explore the properties of paper by constructing and modifying paper airplanes.
Motorized Balancing Toy
Source Institutions
In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.
Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
Fun with Speedboats
Source Institutions
In this activity, learners explore how boats are engineered to achieve speed.
How the Rubber Meets the Road
Source Institutions
In this activity, learners explore how engineers design tire treads to increase safety and reliability.
Carbon Configurations
Source Institutions
In this activity, learners use geometry to predict the shape of carbon. Learners twist and attach chenille stem pieces that represent bonds between different carbon atoms.
Make a Mobile!
Source Institutions
In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.
Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.
Finding the Size of the Sun and Moon
Source Institutions
In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.
Sink or Swim?
Source Institutions
In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.
Parachute Parade
Source Institutions
In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.
There's Always Room For JELL-O
Source Institutions
In this activity, learners cut wells in JELL-O© and load the wells with different detergent solutions.
Paper Table
Source Institutions
In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!
Gecko Feet
Source Institutions
This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).
Cup Draw (Low Tech)
Source Institutions
In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.
