Plants Are Producers
Here's a handy two-part learning exercise that uses an article about plants to assess reading comprehension. After reading the passage, kids answer questions based on the information in the text.
TLS Books
Uranus
After reading an informational text passage, learners answer four multiple choice questions about the third largest planet in our solar system.
TLS Books
Jupiter
Young astronomers read an informational text on the gas giant, Jupiter. Then they answer four multiple choice questions based on what they read.
Beyond Benign
Catalysts and Oxygen
Here is an engaging and hands-on lesson plan that allows high school chemists to demonstrate the effects of a catalyst on various chemicals. They garner knowledge of how reactants and products differ from one another, while...

Acids and Bases
What did one titration say to the other titration? We should meet at the end point! Young chemists perform four experiments: dilute solution, neutralization, titration, and figuring pH/pOH.

What Determines and Limits an Atom's Mass?
Provide learners with the tools to further understand nuclear energy and isotopes. Young chemists investigate the components of an atom's nucleus, use symbols to represent various isotope forms, and use the percent abundance of an...

Making Oxygen and Carbon Dioxide
Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...
Balanced Assessment
Solar Elements
Let your brilliance shine like the sun. Future mathematicians and scientists consider given data on the abundance of different elements in the sun. The assessment task requires consideration of how these different abundances relate to...

Chemical Kinetics
Not all chemical reactions happen at the same rate because some, like explosions, occur quickly and some, like rusting, occur over time. Here, learners explore chemical reactions and their rates in the 16th lesson of 36. Through readings...
National Institute of Open Schooling
Atomic Structure
Learners explain historical findings such as Rutherford and Bohr's contributions, explain wave particle duality, and formulate Heinsenberg's uncertainty principle. They also draw s, p, and d orbitals, explain more historical findings,...
Cornell University
The Making of Macromolecules
Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...
Nuffield Foundation
Investigating Factors Affecting the Breathing Rate of a Locust
Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the...
Biology Junction
The Structure of DNA
Did you know that all life on Earth has DNA? Explore the importance of the molecule by learning about its structure. The unique DNA shape, bases, and bonds allow the incredible diversity seen all over the world.

Taking Apart the Light
Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...
Curated OER
Hydrocarbons
Making models is always memorable. In this activity, physical science starters examine the structure of hydrocarbons using marshmallows, raisins, and toothpicks. They even act as atoms themselves and link arms to represent covalent...
Curated OER
The Carbon Cycle
Here is an interesting science lesson. Pupils discover that carbon, just like water, is absolutely necessary for all living things to survive. They study how it cycles through nature, become familiar with the periodic table, and look at...
