Knee Jerk Reflex (Patellar Reflex)
Source Institutions
In this quick and simple activity about reflexes (third activity on the page), learners conduct a simple test to explore the knee jerk reflex, typically conducted at the doctor's office.
Model Well
Source Institutions
In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.
Afterimage
Source Institutions
In this optics activity, learners investigate afterimages.
Growing Plants
Source Institutions
In this "Sid the Science Kid" activity from Episode 107: My Shrinking Shoes, learners observe how plants change as they grow.
Hot Spoons
Source Institutions
In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.
An Object in Motion
Source Institutions
In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.
Jitterbugs
Source Institutions
In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight.
Pupil to Pupil
Source Institutions
In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.
Newspaper Bridges
Source Institutions
In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.
The Senses of "Unknown Creatures"
Source Institutions
In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.
Sock It To Me!
Source Institutions
In this activity (7th activity on the page), learners use their sense of touch to identify mystery objects hidden in socks.
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.
Minibot
Source Institutions
In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
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.
Animal Math Posters
Source Institutions
These math posters have questions written on them, such as: How fast can a cheetah run? or How long can a giant tortoise live? Post these around the room or leave them out for children to explore.
Plants Count
Source Institutions
In this activity, learners put on their naturalist hats and explore the world around them.
No-Slip Grip
Source Institutions
In this physical sciences activity, learners explore friction. Learners investigate the factors that affect the force required to move an object.
