Curated OER
Chromatography
Students conduct various experiments on chromatography. In this chemistry lesson, students distinguish among the different types of chromatography methods. They explain how the stationary and mobile phase interact with each other.
Curated OER
What Are Mixtures And Solutions?
Students explore mixtures and solutions. In this chemistry lesson plan, students will add different ingredients to jars in order to classify them as mixtures or solutions. There is also a nail balancing activity that can be done at home.
Curated OER
Chromatography
Students research types of chromatography and complete chromatography experiments.
Curated OER
Phases of Matter
Eighth graders practice using correct vocabulary and apply content knowledge related to phases of matter when answering questions about situations or observations from everyday life.
Curated OER
Classifying Materials
Students collect data and make observations on how given element samples respond to the field of a magnet and they calculate the density of the samples by finding the mass and volume.
Curated OER
Unknown Liquids
Students must design and conduct an experiment to determine which unknown liquid has a greater density based on basic information about the liquids and containers. Students are given specific materials to work with.
Curated OER
Density of a Sinker
Eighth graders determine the density of a sinker by first finding the mass and then the volume using a graduated cylinder. Students must write the procedure they use to find the volume of the sinker then apply their data to follow-up...
Curated OER
Density of Minerals
Students determine the mass, volume, and density of two different mineral samples. Students show data and calculations as well as answer questions about the mineral identities.
Curated OER
Threads
Students group observed data, filtering from all their observations the similarities between burring threads. In the second part they make a comparison of a chosen attribute between the two threads.
Curated OER
Starch and Sugar Testing 2
Students design and conduct an experiment to determine which of three solutions contain starch or sugar. This task assess students' ability to make simple observations, design simple experiments, utilize indicators, and make generalized...
Curated OER
Rate of Solution
Eighth graders determine the amount of agitation necessary to dissolve various sized sugar particles. This task assess students' abilities to collect, organize, and interpret data, create appropriate graphs, predict future events based...
Curated OER
Identifying Elements
Students use diffraction glasses to find similarities and differences between observed spectrum of fluorescent light and an incandescent light They work in groups of 4-6 for the experiment/activity part of this exercise.
Curated OER
Let's Take a Rock Apart
Students take a crushed rock and sort the remains of the rock minerals into different categories based on the different properties. In this sorting lesson plan, students learn what makes up a rock and how to sort something into categories.
Curated OER
Acid and Bases - Alien II
Eighth graders determine which of two solutions is more acidic by adding each to a given base. Students have to apply this analysis process to a problem scenario involving an alien creature.
Curated OER
Rain Drops
Students examine drops of water on several materials used on the outside of buildings. They make selective observations on and compare plastic, wood, brick, metal, roof tiles and glass.
Curated OER
Paper Pulp Painting
Students draw an animal on a white piece of paper and add a background of leaves or flowers. They color the drawings and rip up construction paper that is the same color as the colors they chose for their drawings. They turn the...
Curated OER
Salt & Sand
In this science worksheet, students find the terms that are related to the concept of the ocean salt and sand. The answers are found by clicking the link at the bottom of the page.
Curated OER
Density, Iron, and Anemia
Young scholars explain what factors determine density. In this physics lesson, students hypothesize which objects are less dense. They cite the importance of density in everyday life.
