Water Lesson Plan
Students discuss the importance of water in our daily lives. In this physics lesson, students calculate the pressure of water tower systems. They investigate the effect of certain variables using a computer simulation.
Curated OER
HOW IS PH DETERMINED?
High schoolers 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
Density and Buoyancy Experimental Design
Young scholars 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
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
States of Matter
Students explore the states of water. For this physical science lesson, students use ice and dry ice to observe the changes in the state of matter. Students record the results.
Curated OER
Your Weight on Other Planets
Students explore their weight on other planets. In this science lesson, students view a presentation about the other planets and complete a worksheet in which they make predictions about their weight on the moon and other planets.
Curated OER
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
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?
Middle schoolers explore chemical solutions. In this chemistry lesson, students investigate the relationship between three related experiments about solutions. Middle schoolers determine variables that affect the chemical concentration...
Curated OER
A Cup of Sound
Learners study sound and how it is created. For this sound waves lesson students complete a lab activity that shows learners the variables that affect sound.
Curated OER
Looking Blue
Learners 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 manipulate...
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
Selecting Soil For a Sports Field
In this science worksheet, students take part in a laboratory exploration looking at different types of soil. The soil is evaluated in order to fill the role of becoming a sports field.
