Students select appropriate tools and technology to perform tests, collect data, and display data. They construct appropriate graphs from data and develop qualitative statements about the relationships between variables.
Curated OER
Implicit Differentiation
Pupils explore the concept of derivatives. They use implicit differentiation to determine points on a graph where a tangent line is horizontal, vertical, or oblique. Finally, learners find the derivative of a polynomial by...
Curated OER
Volumes of Rectangular Prisms
Students determine the volume of a rectangular prism. They then maximize and minimize the volume given variable side lengths. Finally, they factor the volume equation to determine the side lengths.
Curated OER
Compound Interest
Pupils analyze the variables in the formula of a compound interest. They model the increase or decrease of an investment using compound interest and discuss different compounding periods.

Physics Motion
In this physics worksheet, students identify and locate vocabulary terms related to high school physics motion, including projectile motion. There are 46 words located in the puzzle.
Curated OER
Spectrophotometry Lab
Students use a machine called a spectrophotometer to determine how much light is absorbed by certain substances. Students record the absorbance and the % of light transmitted for different color solutions, graph their results, and then...
Curated OER
THE ROLE OF A CONTROL IN THE EXPERIMENTAL DESIGN
Students study the role of controls. They discuss variables and list conditions, that if not kept the same for both flasks, could effect the outcome of the experiment. They come up with most of the following: Amount and temperature of...
Curated OER
Survival Of The Fittest
Seventh graders examine the concept of an ecosystem and how there is a variety of representations of life that exist there. They look at the equilibrium that is reached in stable communities and how the variable of change in...
Curated OER
Examining Infiltration Rates of Various Soil Types
Students formulate their own hypothesis, determine which variables are important to test their hypothesis, design an experiment in which they collect data. They utilize instruments and tools to measure, calculate, and organize data.
Curated OER
What's Under There?
Young scholars determine ways to make "observations" about unknowns, such as the land beneath an ice sheet or the interior of the Earth, using tools other than sight. They build "mystery boxes" and exchange them with other groups to...
