Rutherford's Enlarged: A Content-Embedded Activity to Teach about Nature of Science
Source Institutions
This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.
Make a Comet Model and Eat It!
Source Institutions
In this activity, learners build models of comets, using edible materials, to learn about comets' structure.
Have Your DNA and Eat It Too
Source Institutions
In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.
Model Eardrum
Source Institutions
In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.
Patches the Cat: A Print-and-Build Paper Sculpture Kit
Source Institutions
In this activity, learners get hands-on with geometry by making a polyhedron kitty sculpture.
Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
Toilet Model
Source Institutions
In this activity, PVC pipe, plastic water bottles and vinyl tubing are used to make a simple working toilet model. The model shows the role of a siphon in the flushing of a toilet.
3...2...1 Puff!
Source Institutions
In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.
Stream Table
Source Institutions
In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.
Mars from Above: Viewing Volcanoes
Source Institutions
In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.
Investigating Convection
Source Institutions
This experiment is designed to illustrate how fluids, including water, have the ability to flow.
Pop Rockets
Source Institutions
In this activity, learners make film canister rocket ships. A fin pattern is glued onto the outside of the canister, and fuel (water and half an antacid tablet) is mixed inside the canister.
Chromosome Models: Karyotyping
Source Institutions
This activity was designed for blind learners, but all types of learners can have a tactile opportunity to construct a karyotype, an organized model of an organism’s chromosomes, conveying the chromos
Mars from Above: Carving Channels
Source Institutions
In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.
Moonlight Serenade
Source Institutions
In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.
Toilet Paper Solar System
Source Institutions
In this activity, learners build a scale model of the solar system using a roll of toilet paper.
Model Wind Tunnel
Source Institutions
In this activity, learners build a miniature wind tunnel to measure force. Learners construct the model out of Lexan plastic, a fan, and a precise digital scale.
The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.
Modeling the Seasons
Source Institutions
This activity provides instructions for learners to create models of the Earth and then to model a "day" on Earth as well as modeling the seasons.
The Watershed Connection
Source Institutions
In this activity, learners interact with a 3-D model of a watershed to better understand the interconnectedness of terrestrial and aquatic environments.
