Scatter Plots
Scholars learn to create scatter plots and investigate any relationships that exists between the variables with a lesson that also show them that statistical relationships do not necessarily indicate a cause-and-effect relationship.

Permeability and Porosity
Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-lesson worksheet to help focus pupils on the task at hand.

Modeling with Polynomials—An Introduction (part 2)
Linear, quadratic, and now cubic functions can model real-life patterns. High schoolers create cubic regression equations to model different scenarios. They then use the regression equations to make predictions.

Reaction Stoichiometry—How Can We Make Chalk?
What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third activity of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...
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 analyzing the...

Plop, Plop, Fizz, Fizz
One of the most recognizable commercial melodies was written in 1977, and led to gastronomical relief around the world. Scholars use Alka Seltzer tablets to measure reactants and calculate the chemical equation for the reaction of NaHCO3...

Looking Inside Planets
All of the gas giant's atmospheres consist of hydrogen and helium, the same gases that make up all stars. The third in a series of 22, the activity challenges pupils to make scale models of the interiors of planets in order to...

Development of a Model: Analyzing Elemental Abundance
How do scientists identify which elements originate from meteorites? Scholars learn about a sample of material found in a remote location, analyzing the sample to determine if it might be from Earth or not. They study elements, isotopes,...

Christa's Lost Lesson: Effervescence
How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Spinners at the School Carnival (Unequal Sections)
Everyone's a winner. Scholars analyze a spinner with five unequal sections, three of which represent winning a toy car and the other two represent winning a toy truck. They conduct an experiment to estimate the number of toy cars and...

Secant Angle Theorem, Exterior Case
It doesn't matter whether secant lines intersect inside or outside the circle, right? Scholars extend concepts from the previous lesson to investigate angles created by secant lines that intersect at a point exterior to the circle....

Probability Rules (part 1)
In statistics, probability rules—literally! Learners use their previous knowledge and explore a set of rules for conditional probability, independent probability, and complements. Given different scenarios, they must determine what type...

Plankton Parents
Plankton are so abundant in the ocean they outweigh all of the animals in the sea. In this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three.

How Much is that Tune?
Tune in for savings! Scholars investigate pricing schemes for two different online music download sites. After comparing the two, they determine the numbers of songs for which each site would be cheaper.
Curated OER
Graphs Galore
Fourth graders conduct surveys to collect data. They analyze and interpret the data, then determine which type of graph is appropriate for the data. Students use the data to make predictions, discover patterns and draw conclusions...

Sustainable Development and Canada's Natural Resources
Students use text information, data and graphs to explain what sustainable development is, and to investigate the rate of consumption of Canada's natural resources. In groups, they graph their findings.
