Special Effects: Titanic and Beyond
Source Institutions
In this activity, learners investigate how geometry plays a role in perspective.
Build a Tree
Source Institutions
This activity (on pages 13-18) has learners build a model tree and then figure out how to make their tree stand up by itself.
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.
Make a Cast of a Tyrannosaurus rex Fossil
Source Institutions
In this activity, learners explore dinosaur fossils by making cast models of a T. rex. First, learners read about and research how dinosaur fossils form.
Waterhouse Hawkins and the Nano Dinosphere Museum
Source Institutions
In this activity, learners explore dinosaurs and fossils by creating a diorama.
Water Cycle in a Bag
Source Institutions
In this activity, learners create a biosphere in a baggie.
Marine Ecosystems
Source Institutions
In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.
Using Bubbles to Explore Membranes
Source Institutions
In this activity, learners use bubbles to investigate the structure and unique properties of cell membranes. Bubbles serve as macroscopic models that mimic the cells' phospholipid bilayers.
Freshwater Ecosystems
Source Institutions
In this activity, learners create a freshwater ecosystem in a large plastic bottle. Learners cut and prepare bottles, then fill with water, aquatic plants, snails and fish.
Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
Create a Coral Reef
Source Institutions
Educator Amy O'Donnell from the American Museum of Natural History guides learners to create a diorama of a coral reef.
Sea Turtle Populations
Source Institutions
In this activity (on page 2 of PDF under GPS: Sea Turtles Activity), learners will model how a sea turtle population changes over time, from eggs to adults, using puffed rice.
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.
Finding Fossils
Source Institutions
This activity (located on page 4 of the PDF under GPS: Baby Dinosaurs Activity) is a full inquiry investigation to determine the age of fossils based on where they are discovered.
Reebops
Source Institutions
In this genetics activity, learners create imaginary creatures known as "Reebops" to explore the relationships between genes and inherited traits.
Mystery of the Disappearing Cottonwoods
Source Institutions
Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
