Pointing at Maximum Power for PV
Following detailed directions, teams collect the voltage and current outputs of a photovoltaic cell by adjusting the resistance. Using the collected data, they determine the highest power output. Implications for weather and a large...

Aspirin Analysis
Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand.

Using The Scientific Method
Middle schoolers are given a problem or hypothesis, they can create a relevant experiment using the steps to the scientific method. They collect quantitative and qualitative observations in scientific experiments. Students identify the...

Science: Objects That Rotate with Gravity
Students conduct experiments in gravity by rolling objects down an incline and determining which ones roll slower than others. As part of the experiment, they design objects which will roll the slowest. Using digital movie cameras or...
Curated OER
Bleach Chemical Reactions
Students learn what happens when bleach comes in contact with various cloth fibers, chemical colors, nature and synthetics.
Curated OER
Power
Students analyze people's sources of power: resources, organization and numbers. They determine when and how power is exercised by analyzing specific examples.

Watch That Plant Grow
Middle schoolers examine the growth of marigolds in a greenhouse environment. They chart data in spreadsheets showing plant growth over time and under a number of conditions. They record measures of plant height and greenhouse temperature.

Ocean Acidification: Whats and Hows
Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Rain Gardens for Controlling Excess Runoff
Students address the idea that human beings live within the world' ecosystems. They discuss how humans modify ecosystems as a result of population growth, technology, and consumption. Students discuss how the human destruction of...

Altering a Plant Environment
Students investigate what a controlled group is by creating an experiment. In this plant growth lesson, students identify the different parts of a plant and discuss what is needed for a plant to be successfully grown....
Curated OER
Fortune Teller Fish
Students demonstrate how to create and test a hypothesis. They design an experiment and set up a variable, experimental group and control group.
Curated OER
Epidemiology: Graphing and Analyzing Health Data
Students graph data on fetal and infant mortality rates collected by the Centers for Disease Control and Prevention. They identify trends in the data and propose potential causes for the trends.
Curated OER
Exothermic Reactions
Students experiment, observe, measure, and analyze what occurs during an exothermic reaction. They safely design an experiment, control variables, and properly dispose of materials.
Curated OER
HOW IS PH DETERMINED?
Students 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.
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
Survival
Students determine the best material from which to make a jacket to keep the body warm in a cold, dry, windy climate. This task assesses the student's ability to perform an entire investigation. In this question the independent...

Velocity and Acceleration
Twelfth graders look at local speed limits and traffic controls and see if they are reasonable. They plot the displacement and time to represent velocity, develop a plan for improving the current system, and organize experimental...

Investigating the Biosphere With Planetary Models
Students create a biosphere using the computer program SImEarth. They work in small groups to create "Daisyworld" in which they model aspects of the Gaia hypothesis. They form a question to answer and choose variables to investigate in...
Curated OER
The Lift Equation
Students use the FoilSim educational software program to complete an activity regarding lift. They solve a multivariable equation for each of the variables and apply the results to various problems in different situations.
Curated OER
Pendulums
Students construct a pendulums and experiment with what variables change or effect the rate at which they swing through an arc. They are assessed on scientific inquiry including the following skills: observation, data collection,...
Curated OER
Shells and Subshells
Learners 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
Density and Buoyancy Experimental Design
Students must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."
