2007 U.S. National Chemistry Olympiad Part II
Eight multi-step chemistry problems, including analyzing a titration, writing equations, predicting products and limiting reagents, calculating concentrations of ions, and using stoichiometry to solve for unknowns in reactions make up...
Curated OER
A Self Directed Inquiry into the Identification of Unknowns
Students gain experience in designing an experiment and use logic in selecting specific tests for unknowns. Students recognize the use of spreadsheets in helping one to make clear comparisons.

Discovering the Milky Way
What do you call a tiny collection of galaxies? A puny-verse! Young scholars graph data gathered by scientists studying Cepheids. They attempt to identify a relationship between the variables through standard and logarithmical...
NOAA
Vertebrates II
Mammals of the ocean unite! Or not. The 20th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates how warm-blooded marine mammals survive in water. In the class activity, learners use...

Temperature and the Tomato
You will need a photovoltaic system and monitor at your school in order to obtain all of the data required to thoroughly implement this lesson. Your class monitors daily temperature and insolation amounts over a two week span of time....
Curated OER
Fizzy Pop
Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...
Curated OER
Soil pH & Plants
Learners investigate the pH of the soil in which different plants grow. They design and carry out an experiment to determine the factors that affect the growth of a population of plants, identifying and controlling major variables...
Curated OER
Biodiversity of Ponds
Students study the biodiversity in pond water. In this biodiversity lesson plan, students observe 3 samples of pond water using a pond water identification sheet. They record their findings and identify the organisms they find, the...
