Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.
Introduction to the New Chain Gang
Source Institutions
In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
Exploring the Nanoworld with LEGO Bricks: Probing the Structure of Materials at the Nanoscale
Source Institutions
In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.
Exploring the Nanoworld with LEGO Bricks: Structures at the Nanoscale
Source Institutions
In this activity (pages 7-16), learners model various crystal structures with LEGOs. This activity also contains additional links that explain how to create other crystal structures.
The Great Plankton Race
Source Institutions
In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
Our Place in Our Galaxy
Source Institutions
In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.
Crystal Packin' Mama
Source Institutions
In this activity, learners investigate the basic crystal structures that metal atoms form.
It's all Done with Mirrors
Source Institutions
This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.
Freezing Lakes
Source Institutions
In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.
Crunch and Munch Lab
Source Institutions
In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.
A Crayon Rock Cycle - Igneous
Source Institutions
This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.
Exploring the Nanoworld with LEGO Bricks: Structure-Property Relationships at the Nanoscale
Source Institutions
In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.
What's in Your Blood?
Source Institutions
Doctors often send a sample of blood to a lab, to make sure their patients are healthy.
Exploring the Nanoworld with LEGO Bricks: Structures and Their Construction at the Nanoscale
Source Institutions
In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.
A Crayon Rock Cycle- Sedimentary
Source Institutions
This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.
