Why Doesn’t the Ocean Freeze?
Source Institutions
In this activity, learners explore how salt water freezes in comparison to fresh water.
Make a Dinosaur Model
Source Institutions
In this activity, learners explore dinosaur skeletons, anatomy, and locomotion. Learners compare and contrast dinosaur skeletons and drawings.
Earth's Water: A Drop in Your Cup
Source Institutions
This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour
Disappearing Statues
Source Institutions
In this activity (on page 8), learners model how marble statues and buildings are affected by acid rain.
Water Underground
Source Institutions
Many people get water from a source deep underground, called groundwater.
Water "Digs" It!
Source Institutions
In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.
Fossil Dig Site
Source Institutions
In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.
Invent a Plant
Source Institutions
In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
Let's Make Molecules
Source Institutions
In this activity, learners use gumdrops and toothpicks to model the composition and molecular structure of three greenhouse gases: carbon dioxide (CO2), water vapor (H2O) and methane (CH4).
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.
T. rex Cretaceous Treat
Source Institutions
In this activity, learners make edible T. rex teeth (with adult assistance). The treat is a white and dark chocolate covered banana on a stick.
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.
Fruit Fly Trap
Source Institutions
Build a fruit fly trap out of a 2-liter plastic bottle and some rotten fruit! Fruit flies are easy to catch in warm weather. Once you catch some, you will be able to see their life cycle up-close.
Make a Lake
Source Institutions
Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?
Layered Fossil Parfait: Deeper is Older
Source Institutions
In this activity, learners explore dinosaur fossils by making an edible treat. First, learners read "Dinosaur Bones" by Aliki to examine how fossils are formed.
Digging Deeper!
Source Institutions
In this activity, learners explore dinosaur skeletons and anatomy. Learners make observations about a T. rex skeleton diagram and then measure the skeleton length and width.
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.
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.
