Solubility Product of a Hydroxide
Students determine the solubility product constant and the concentration of a hydroxide. In this solubility product lesson plan, students use a solution of calcium hydroxide to neutralize a known concentration of hydrochloric acid. They...
Curated OER
Mass-Mass Relationship
Students investigate mass-mass relationships in the lab. In this mass-mass relationship lesson plan, students mix sodium carbonate with hydrochloric acid to produce sodium chloride, water and carbon dioxide. Students use the amount of...

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.

i-Density Crisis
Eighth graders determine the density using mass and volume. In this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known density.
Santa Monica College
The Density of Liquids and Solids
There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...
Curated OER
The Relationship Between Salinity and the Density of Water
Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...
Curated OER
Building Polymer Cup Speakers
Students investigate sound waves and they build audio speakers. In this audio speakers and sound lesson, students explore how to make quality audio speakers. As a team they build their own speakers to have clarity in sound, quality in...
Curated OER
Ice Cream Blizzards
Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...
Curated OER
Finding Mass
Student measure mass to discover how pennies have changed in their composition. In this measurement lesson, 8th graders investigate through an open-ended problem to discover how the US pennies composition changed in the 1980's.
Curated OER
Pendulum Activity
Fourth graders conduct a lab activity that measures the factors that change the swing rate of a pendulum. They create a hypothesis and test it during the experiment. They record their observations using the recording sheets and journal...
Curated OER
Icebergs Ahead!
Young scholars examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.
Curated OER
Studying Plant Development Through Metabolic Activity
A hands-on activity which allows students to learn about cellular respiration. This lesson contains a range of investigations testing the rates of cellular respiration to demonstrate the relationship between metabolic rates of...
Curated OER
Chemical or Physical?
Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...

Efficiency Means Getting More for Less
Middle schoolers measure water and make predictions about efficiency.
Curated OER
Respiratory System
In this health worksheet, students examine the human body and make mental connections to the target function highlighted in the sheet.

Project Geode
Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly lesson, learners use scientific equipment to collect...
Pingry School
Determination of the Molar Mass of an Unknown Acid
Acids and bases have a love-hate relationship. They balance each other so nicely, but they are complete opposites! Learners use these concepts and titration to calculate the molar mass of an unknown substance. The experiment document...
Curated OER
Performance-based Assessments for AC circuit Competencies
In this electronics worksheet, students predict the behavior of 51 circuits and compare their prediction with actual values. They make the necessary corrections when values don't match.
Curated OER
Project Geode
Young scholars predict the appearance of a geode's internal structure based on its mass and density. They form a hypothesis based on the data they collect. They also identify common minerals found in Illinois.
Curated OER
Why Are Cells So Small?
Students examine the relationship between cell surface area and the ability of materials to diffuse through a cell. They participate in an experiment in which they determine which materials diffuse easier than others. They complete...
Curated OER
Surface Tension and 3D Soap Films
Young scholars are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.
Curated OER
Elasticity of Gases
Young scholars investigate gas laws and apply them in experimental conditions. Using an apparatus composed of a syringe and wooden blocks, they experimentally verify Boyle's and Charles' laws of gases.
