Glitter Slime
Source Institutions
In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.
Number Cruncher
Source Institutions
In this online puzzle game, learners need to choose a path from a starting number to a goal number. Along the path are simple operations (e.g.
I M O K. U R O K.: You Can Make Sentences Without Words!
Source Institutions
Can you read the sentence "I C U"? Not really - but if you say each letter aloud, you'll say the simple sentence, "I see you." What if you change the "C" into a picture of an eye?
Exploring Symbiosis
Source Institutions
In this activity, learners discover which plants and animals have symbiotic relationships and how this impacts each organism.
Make Your Own Deep-Sea Vent
Source Institutions
In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
Let's Go Ice Fishing
Source Institutions
In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.
Super Shrinkers
Source Institutions
In this activity on page 14 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners turn plain pieces of recycled plastic into shrunken works of art.
Simple Pop-Up Mechanisms
Source Institutions
