How Old Are They?
Here is a (great) lesson on using parentheses! The task requires the expression of ages using algebraic expressions, including the distributive property. Pupils use their expressions to determine the individual ages.
PhET
Molarity
All chemists know that moles are made of molecules. Individuals see how changes in the amount of solute affect the concentration of the solutions. By manipulating solute amounts (moles), solution volume (liters), and solute types, the...

Neuron
Neurons send electrical signals throughout a body based on chemical communication. Individuals stimulate a neuron to see the effects. They notice the sodium-potassium channels along with ions, concentrations, and a membrane potential...
Balanced Assessment
Fit-Ness
Serve four towns with one bus route. Pupils develop a bus route that meets certain criteria to serve four towns. They determine which of the routes would best serve all of them. Individuals then hypothesize where a fifth town should be...
Balanced Assessment
Ostrich and Seahorse
Examine the relationship between ratios and scale. Young math scholars compare ratios of two models. They use the ratios to make a comparison between the two models. Each image uses a different scale, which requires learners to think...

Double Wells and Covalent Bonds
Quantum tunneling plays an important role in nuclear fusion, the energy source of the sun. This simulation explores tunneling, double wells, and covalent bonds by allowing individuals to manipulate potential and total energy to learn...
Balanced Assessment
Disc-Ness
Transform your scholars into mathematicians as they develop their own geometric definition. The task asks individuals to compare cylindrical objects and create a definition for the disc-ness of each object. They may use any method and...
Balanced Assessment
Blirts and Gorks
Start a trend by using blirts and gorks as your standard unit of measures. The activity asks learners to take a known measures of blirts and gorks and develop a conversion ratio. Individuals use both perimeter and area measures of...

Writing Equations Using Symbols
Build upon prior equation writing experience to create more complicated equations. Lesson one in a 33-part unit builds upon the class members' sixth and seventh grade experience of writing linear equations. Several examples provide...
Advocates for Human Rights
Refugees and Asylum Seekers
To gain a deeper understanding of the plight of refugees and asylum seekers, class members read stories written from the point of view of an emigrant, map the individual's journey, and note the human rights affected by each stage of the...
