Curated OER
Research Ethics
Students develop an ability to distinguish between simple error, misconduct and fraud. Students are lead to consider a widening circle of the consequences of misconduct and fraud. They expand their knowledge on the self-regulating...
Curated OER
Acid Rain
Learners create acid rain using carbonic, nitrous, nitric, and sulfurous acids.
Curated OER
Strength of Water
Students perform experiments using flexible bottles of water and eyedroppers partially filled and placed in the bottle. They record what happens when they tighten the bottle lid and squeeze the bottle.
Curated OER
Testing Battery Combinations
Fourth graders examine the required combinations of plates and predict which combination will generate the most and least current and voltage. They use an ammeter and experiment with combinations of their own testing and record each...
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
Limiting Reagent
Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...
Curated OER
Mixtures
Sixth graders experiment with mixtures. For this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.
Curated OER
Measuring Snowfall
Students predict the amount of snowfall for the week and measure snowfall. In this measuring snowfall lesson, student use a precipitation gauge to measure the week's snowfall; and analyze the data to determine whether or not...
Curated OER
Using Newsprint as a UV Detector
Students investigate the effects of UV radiation. In this earth science lesson, students explain how the time of day relate to UV abundance on Earth. They determine if weather affects the amount of UV that Earth receives.
Curated OER
Scientific Inquiry: Periodic Motion
Students construct their own pendulum. In this physics lesson, students design an experiment to find the factors affecting its period. They formulate a conclusion based on experimental data.
Curated OER
Multiplying Microbes
Students examine environmental conditions that effect bacteria growth. They culture bacteria, design and conduct an experiment, and identify the conditions that effected the bacteria growth using the scientific method.

How Can You Study Things You Can’t See Like: Atoms?
Students simulate how scientists studied things they can't see like atoms. In this chemistry lesson, students predict what is inside the numbered obsertainers. They design a way to investigate what's inside without opening it.
