Curated OER
Exploring Rocks
Students collect and examine rocks. They record information about the rocks they have collected in their notebooks. They compare and contrast different rocks and complete a class chart at the end of the lesson.
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
Temperature and Enzymes
Students compare the times it takes the milk in each of two cups to curdle. They are told that an enzyme that is added to the milk, rennin, is involved in the natural curdling process of milk. Students are asked to consider what...
Curated OER
Water String Travels
Students examine the properties of water and conduct experiments demonstrating adhesion. Using a wet string, they observe water moving by adhesion from a beaker full of water to an empty one. They draw cartoons of water molecules talking...
Curated OER
Rate of Solvation
Young scholars test factors that may affect the rate at which sugar dissolve in water. They conduct two studies: One is to test the effect of temperature on the rate of solvation and the other is to test a factor which Students come up...
Curated OER
Magnets
Young scholars investigate the magnetic attraction of different materials by observing a demonstration, and review the words "attraction" and "materials." Next they conduct exploration of a number of materials which have different...
Curated OER
Salt Water Wedge
Students conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...
Curated OER
Watch Your Step!
Students examine the physical characteristics of insects and spiders. Students research the vaious ways in which insects move. They then observe and record the metamorposis of one of more insects. They complete the lesson by...
Curated OER
Ionic Bonding
In this ionic bonding learning exercise, students observe diagrams about ionic bonds and crystal formation. They answer 37 short answer questions about the properties of monatomic ions, polytomic ions and write correct formulas.
Curated OER
Glacier Climbing
Students discover where glaciers exist and how they move. In this glacier lesson, students work in groups to create a glacier in a replica valley and observe its properties.
Curated OER
Playing With Polymers
Students explore the world of polymers. In this chemistry instructional activity, students make polymers and observe their properties. Follow-up questions and extension activities are included.
Curated OER
Water and Ice
Students explore the physical properties of water. In this water activity, students explore water as it changes states. They observe, measure and use communication skills to describe change.
Curated OER
Water and Ice
Students explore the physical properties of water. In this water lesson, students observe, measure, and describe water as it changes state. There are 2 extensions for this lesson that one can access via the Internet links provided.
Curated OER
Blowing Bubbles, Blowing Colors
Students examine the properties of bubbles by testing different bubble making materials. In this scientific experiment lesson, students create a bubble brew with different soaps while observing the different strengths and sizes of the...
Curated OER
Rock Talk
Students read a book about rocks and complete a rock analysis activity. In this rock study lesson, students read the book Everybody Needs a Rock and select a rock to observe and describe. Students record the properties of rocks, classify...
Curated OER
Slope and Tangent
Students differentiate between the slope and the tangent of the horizontal. In this precalculus lesson, students examine slopes created by tangent lines. They observe the angle formed using properties of the unit circle.
Curated OER
Faces, Vertices, Edges
Students identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.
Curated OER
Constructing Parallel Lines
Students construct parallel lines using a protractor and a straightedge. In this geometry lesson, students identify the properties of parallel lines. They use Cabri to graph and observe the lines.
Curated OER
Exploring Limu Diversity
Young scholars explore limu diversity. In this ocean ecosystem lesson, students classify limu according to its physical properties. Young scholars work in small groups to generate scientific observations and sort limu by characteristics.
Curated OER
Conductivity of salt Solutions
Learners investigate the concentration level of solutions. In this math/science instructional activity, students identify three different ionic compounds. They predict the conductivity of each using their collected data.
Curated OER
Classifying Rocks
Learners classify rocks into groups after they observe the rocks and identify properties that can be used to divide them into groups. They then identify other properties that could be used to classify other objects into groups.
Curated OER
Color Dots 3
Students make simple observations, test mixtures, and make generalized inferences from their observations. They observe bleeding of colored inks with water.
