Reading DNA
Source Institutions
In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.
Ready to Observe: Enhance Your Telescope Experience
Source Institutions
This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.
DNA and Histone Model
Source Institutions
In this activity, learners construct a 3-D paper model depicting how histone, acetyl and methyl molecules control access to DNA and affect gene DNA expression.
Carbon Cycle Roleplay
Source Institutions
In this creative roleplay activity, learners will explore the various processes of the carbon cycle using movement and props to aid in comprehension.
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.
Survival of the Fittest: Battling Beetles
Source Institutions
This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection through data collection and pattern recognition.
"Build a Bacterium" Scavenger Hunt
Source Institutions
Working in small groups, learners receive a written scenario regarding a bacterium with a certain goal it must carry out.
Water Walk
Source Institutions
Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.
Harmful Algal Blooms: In Full Bloom
Source Institutions
In this activity, learners will investigate the impacts of harmful phytoplankton using NOAA's Coastal Services Center Harmful Algal Bloom Forecasting (HABF) Project data.
Corals on Acid
Source Institutions
The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.
Terrestrial Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.
Trees: Recorders of Climate Change
Source Institutions
In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho
The Great Fossil Find
Source Institutions
On an imaginary fossil hunt, learners "find" (remove from envelope) paper "fossils" of some unknown creature, only a few at a time.
Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
Making Mosaics
Source Institutions
In this archaeology meets art activity, learners make a mosaic and consider the ways in which art communicates.
Underwater Hide and Seek
Source Institutions
In this activity, learners experience firsthand how marine animals' adaptive coloration camouflages them from prey.
Breathing Blue
Source Institutions
In this activity, learners test exhaled breath for carbon dioxide and learn how to use an indicator as a simple way to measure pH.
Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.
Exponential Models: Rhinos and M&M’s ®
Source Institutions
In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.
