What's in a Penny?
Source Institutions
In this chemistry activity, learners use chemical reactions to observe the composition of an alloy.
Rocking Changes
Source Institutions
In this earth science activity, learners conduct a series of short experiments to explore how rocks change.
Electromagnet
Source Institutions
In this activity, learners build an electromagnet using a nail, a cork, a battery, and electrical wire. Use this activity to demonstrate how electric currents produce magnet fields.
Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.
Pósteres de Creatividad y Matemáticas
Source Institutions
Exponga estos pósteres en el salón o déjelos donde los chicos los puedan explorar. Los chicos buscan las respuestas en libros de consulta, explorando el salón, y usando su creatividad.
Milk Plastic
Source Institutions
In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.
Rotating String Shapes
Source Institutions
In this group activity, learners make multi-sided polygons with string.
Take It in Stride
Source Institutions
In this health and fitness activity, learners focus on the importance of daily physical activity, specifically walking.
Parachuting Pinwheel
Source Institutions
Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.
Dinosaur Skull and Body Length Predictions
Source Institutions
In this activity (located on page 2 of PDF under GPS: Baby Dinosaurs Activity), learners will look for a relationship between skull size and body length among various dinosaurs.
Sea Turtle Populations
Source Institutions
In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.
Extreme Kicking Machine
Source Institutions
In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.
Motorized Car
Source Institutions
In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.
Shake a Shrub
Source Institutions
This is an activity where learners will discover what types and how many insects live in their own backyard.
Pop Fly
Source Institutions
In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!
Kicking Machine
Source Institutions
In this design challenge activity, learners build a machine that kicks a Ping-Pong ball into a cup lying on its side 12 inches away.
Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.
Making Circuits
Source Institutions
In this activity, learners explore electricity and conductivity to find that many things conduct electricity including copper, pencil lead, fruit, play-doh, and even people!
Cabbage Chemistry
Source Institutions
In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.
Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
