Curated OER
HOW IS PH DETERMINED?
Learners 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
Mass, Volume and Density
Pupils compare and contrast the mass, volume, and density of various objects. They use a triple beam balance, measure and record the volume of a cup of water, and discuss the results.

Whose Breakfast isn't for the Birds?
Students explore coffee production. In this cross-curriculum rainforest ecology lesson, students research regions where coffee comes from and investigate how the native birds in the rainforest are effected by coffee...
Curated OER
Genetic Traits
Young scholars supplement their study of genetics by collecting and analyzing information about their own and their classmates' characteristics and traits. Students create a database of traits and characteristics to compare and contrast.
Curated OER
Identifying Acids and Bases
Sixth graders observe the physical and chemical change that can occur in an acid and a base. In this acids and bases lesson plan, 6th graders use cabbage juice to identify, compare, and contrast acids and bases.
Curated OER
Introducing Temperature Measurement
Students explore temperature and use Celcius thermometers to measure and graph the temperature in the classroom daily. They estimate what they think the temperature might be and then find the actual temperature in the room.
Curated OER
Toothpick Fish
Students experiment with genes and environment for a population of "Toothpick Fish."
Curated OER
Some of Its Parts
Students study a can opener to find the important parts that make it possible to take the lid off a can of food. They then use this information to decide what new or different subsystems could be added to make it better and explain how...
Curated OER
Upwelling Terrestrial Radiation
Students calculate the hourly irradiance of the earth at a site given the near-surface air temperature of the site. They compare the calculated values of irradiance with those measured by instruments at the site. Students need to...
Curated OER
Wildlife Sampling-Capture-Recapture
Seventh graders simulate the capture-recapture method of population sampling using beans. In this biology lesson, 7th graders calculate the total population of beans in the bowl. They assess whether this method is reliable or not.
Curated OER
Web-search And PowerPoint Presentations-The Cell
Sixth graders create a PowerPoint presentation using information that they have compiled from their web search and rubric web sites, text and other applicable references. They work in pairs to complete these searches and projects.
Curated OER
Landfill Project
Students explore impact of garbage on environment, examine waste management operations and how they can directly impact environment, implement ways to lower household garbage, and make STELLA Model about garbage flow and use model to...
Curated OER
Rubber Band
Eighth graders investigate what would happen to the length of a rubber band as more and more rings were hung on it. They base their explanation on what they observed, and as they develop cognitive skills, they should be able to...
Curated OER
Respiratory System
Students identify the parts of the respiratory system and how they interact. They define vocabulary words and draw an outline of themselves and label the parts of the respiratory system. They distinguish between healthy and unhealthy...
Curated OER
Lesson 6: Resonance
Students participate in a lab activity using three tuning forks of different frequencies and a Resonance Tube Set purchased from Sargent-Welch to take measurements of resonant lengths of the tuning fork frequencies. Students then try to...
Curated OER
Go Jump In The Lake!
Middle schoolers experiment with local lake water to determine the health of the lake waters. They explore the human impact on the lake water, hypothesize and share inferences in a scientific report.
Curated OER
Ecology and the Conservation of Natural Resources Lesson 2
Students compare and contrast abiotic and biotic factors. They discuss how these factors effect ecosystems. They answer questions to complete the lesson.
Curated OER
Swingers
Students investigate the motion of a swinging pendulum. They experiment with a pendulum to find out why it might swing at different speeds at different times.
Curated OER
The Law of Inertia
Students practice the 4 question strategy to form more questions and develop further experiments. The four questions are engage, explore, explain, and elaborate. They use the 4 question strategy on an investigation involving the mass...
Curated OER
Gravity Lesson
Fifth graders study the effects of mass on gravity. In this gravity lesson plan, 5th graders make model parachutes and helicopters in order to apply the scientific process and find out the effects of mass on drops of the 2 objects.
Curated OER
Pump It Up
Students study the anatomy and functions of a heart. In this heart study lesson, students read a book about the heart and study a plaster heart model. Students take their own pulse in various stages of rest as well as active...
Curated OER
How much Carbon Dioxide is in My Seltzer Water?
Learners discover the law of conservation of mass though experimentation. In this chemistry activity, students experiment with acid - base indicators to determine the presence of carbon dioxide. Learners complete the labs with...
