The Blizzard of 1993
Students read and interpret the information from a barograph from a major winter storm. This task assesses students' abilities to interpret and analyze graphs, construct data tables and graphs, generalize, infer, apply knowledge of...
Curated OER
Let the Sunshine in
Students collect and analyze data to study wavelengths of visible light. They cover Styrofoam cups with three different colors of sun filtering products and shine a lamp directly on the cups. They determine the most effective filtering...
Curated OER
Sedimentary Rocks
Second graders receive an introduction to the rock cycle. They dicuss the geologic rock cycle. They create a simulation of a sedementary rock.
Curated OER
Ice Cream Chemical and Physical Changes
Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...
Curated OER
Graphical Determination of Density
Students determine the density of metal shot by a graphical method using significant digits in making measurements and calculations. Students graph a seris of laboratory measurements and determine density from a mass verses volume graph.
Curated OER
Basic Electric Circuits
Students calculate the resistance across a bank of resistors in a series, parallel and combined circuit. Using new vocabulary words, they define and describe them in a scientific manner. After stating Ohm's Law, they solve electrical...
Curated OER
Mystery Card 3
Students will make a circuit on a mystery card. They will connect wires, bulbs, and battery to form an electrical tester. After students learn how to make one following the directions, they can create their own mystery card by...
Curated OER
Induction: Inquiry in Action
Students investigate the factors that affect the induced current in a loop of wire. They discuss Faraday's Law and Lenz's Law. Students identify the different variables that affect the magnetic flux and calculate the magnetic flux...

Inventions 2: The Impact
Students research inventors and inventions and their impacts. In this invention lesson, students research inventions and their affects in good and bad ways.
Curated OER
Science with Mud!
Eighth graders give some examples of chemical reactions they see everyday. In this chemistry lesson, 8th graders investigate how much water soil can hold. They collect data and compare results with others.
