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
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...

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
States of Matter
Students explore the states of water. In this physical science lesson, students use ice and dry ice to observe the changes in the state of matter. Students record the results.

Build Your Own Parachute
Students study the basics of parachuting. In this flight and aerodynamics lesson students make a simple parachute and investigate different variables that can cause potential problems.
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."
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
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
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
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...
Curated OER
What Makes you Hot?
Students manipulate different variables in a model and make inferences about the temperature on Earth. In this heat lesson students calculate the blackbody radiation of an object at a certain temperature.
Curated OER
Does Size Matter?
Students explore chemical solutions. In this chemistry lesson, students investigate the relationship between three related experiments about solutions. Students determine variables that affect the chemical concentration of each solution.
Curated OER
A Cup of Sound
Students study sound and how it is created. In this sound waves lesson students complete a lab activity that shows students the variables that affect sound.
Curated OER
Looking Blue
Young scholars participate in a research project that is exclusively using the internet. The author states that traditional labs are hard to conduct for a light lab. This one uses the internet with the intention that students can...
Curated OER
Respiration
Students study the gas exchanges that occur during cellular respiration. They observe what happens as a result of a number of variables on the rate of respiration. They use microrespirometers to measure the oxygen consumption of...
Curated OER
How Many Drops?
Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...
Curated OER
Geology Quiz- Common Rocks
In this earth science quiz worksheet, learners attempt to guess the name of the rocks based on the descriptions that are given on the page. They determine the names of 10 rocks that are igneous or sedimentary, and check their work with...
Curated OER
Making Plastic
Students experiment to create a plastic solution. In this science instructional activity, students use sodium borax and polyvinyl alcohol to create their solution, then identify, discuss, and chart observations on the end product.
Curated OER
Physics Lab Rockets
Learners construct and test balloon rockets and a model rocket. In this rocket science activity, students use an inquiry-based method to master balloon rockets and have a shoot-off with the goal of attaining the highest altitude. Next,...
Curated OER
Making a Battery and Energy Transformation
Seventh graders determine what makes a battery work. For this battery lesson, 7th graders brainstorm ideas about how they think batteries provide energy. They perform an experiment in which they work as a team to assemble a battery. They...
Curated OER
Why Could the Hindenburg Float?
Tenth graders experiment with floating and sinking objects and heavy and light liquids, using correct terms, like density, to explain what happens. In this Hindenburg lesson, 10th graders watch a demonstration called the invisible...
