Tiny Tubes
Source Institutions
In this activity, learners make "totally tubular" forms of carbon. Learners use chicken wire to build macro models of carbon nanotubes.
Avalanche
Source Institutions
In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.
From Polliwog to Frog
Source Institutions
In this activity, learners discover how frogs' bodies change while growing from a tadpole to a frog. Learners create a simple craft that gives a visual display of the metamorphosis process.
Modeling Limits to Cell Size
Source Institutions
This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.
Space Stations: Bones of Contention
Source Institutions
In this activity, learners make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.
Dry Ice Comet
Source Institutions
In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails.
Sled Kite
Source Institutions
In this activity, learners build a sled kite that models a type of airfoil called a parawing.
Fossils: Observing, Making and Learning
Source Institutions
In this activity, learners explore how casts of fossilized bones are created and used to learn about dinosaurs. Learners make observations, draw diagrams and share their findings.
Catapult
Source Institutions
In this activity, learners construct their own small catapults using simple materials. Learners follow visual instructions to build their launching device.
Build a Solar System
Source Institutions
In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei
Introduction to the New Chain Gang
Source Institutions
In this activity, learners use pop-beads to understand the characteristics and properties of polymer chains.
Pyramids and Triangles
Source Institutions
Straws and pipe cleaners are terrific materials for building models of pyramids and cubes.
Single Serving Volcanism
Source Institutions
In this activity, learners eat a snack and make a model of the plumbing system of a volcano.
Yummy Gummy Double Helix
Source Institutions
In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.
Scaling an Atom
Source Institutions
In this activity, learners make a scale model of an atom to see how big or how small an atom is compared to its nucleus. Learners will realize that most of matter is just empty space!
Gel Electrophoresis
Source Institutions
In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
Make a Model Caldera
Source Institutions
In this quick activity (page 2 of PDF under GPS: Lava Flow Activity), learners will model how large depressions near the top of a volcano are formed by using an inflating and deflating balloon submerg
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.
Deep Sea Diver
Source Institutions
In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.
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.
