Simple Bar Graphs Using Excel
Young scholars create original survey questions, and develop a bar graph of the data on paper. They input the survey data using two variables onto an Excel bar graph spreadsheet.
Curated OER
HOW IS PH DETERMINED?
Young scholars estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.

Batteries in Series
Eighth graders examine batteries in a series circuit and the associated voltage. They determine, through inquiry and problem solving, that the total voltage of batteries in a series is the sum of the voltage of each battery. They design...
Curated OER
Exploring Function Graphs
Tenth graders investigate three different sets of data that relate temperature to another variable in the physical world. These illustrate linear, inverse and exponential relationships.
Curated OER
Seesaw Balances
Students determine how the weights of 7 objects on a seesaw can vary and still be in balance. They also write equations in algebraic terms, how to change 3 variables in an equation expressed in algebraic terms to obtain the correct...
Curated OER
How Many More on a Graph?
First graders examine data on a graph and determine which variable on the graph has more. They draw pictures of their family members and determine which families have more members than other families. Using squares of paper to depict...
Curated OER
Shells and Subshells
Students explore how to show evidence of subshells and electron filling on the visual scale. They examine subshell filling and evaluate unknowns based on the atomic emission spectrum. Students design an experiment to identify colors of...
Curated OER
How Can Sounds Be Different
Second graders explore energy and motion. They investigate how sound energy moves in waves. Students explore how sounds are varied and how the instruments that make those sounds are built. They observe sounds being produced and predict...
Curated OER
An Enzyme- Substrate Model
Students explore reaction rates of an enzyme-mediated reaction. They examine the effects of environmental variables on enzyme function. Students collect, graph, and analyze data relating to the reaction.
Curated OER
The Estimation Station
Students challenge "common knowledge" against newly learned estimation strategies and put those strategies into use. They consider variables in estimating different groups of objects and practice skills of representing numbers.
Curated OER
Cold Fronts
Students determine its' direction of movement, and list at least five weather conditions associated with the specific front, given animations of several atmospheric variables during a cold front passage. They list at least three weather...
Curated OER
Activity #6 How Fast Do Reactions Go?
Students name the factors (concentration, temperature, and a catalyst) which can affect the rate of a chemical reaction. They use their knowledge of particle theory to explain their observations. Pupils comprehend that the...
Curated OER
Introduction to the Scientific Method
Students designs and conduct a scientific experiment that identifies the problem, distinguishes manipulated, responding and controlled variables, collects, analyzes and communicates data, and makes valid inferences and conclusions.
Curated OER
Relative Humidity & Dew Point
Students use a 24-hour graph of air temperature, relative humidity, and dew point to describe at least one reason why the variables change (or don't change) during the day. They use given scenarios to identify and describe the problems...
Curated OER
Dryline Characteristics
Students view animations of several atmospheric variables (e.g., temperature, rainfall) during a cold front passage and locate the dryline, determine its direction of movement, and list at least two weather conditions associated with the...
