Turbidy and Water
Students use observation skills in assessing the water quality of water samples in this activity and learn that the tastes and preferences of others can be different.
Curated OER
Sound and Hearing - Internet Research
Students use a website to help them recognize that sound is generated in a variety of ways and from different sources. They determine that sounds vary in tone and loudness, and learn there are different ways to describe sound.
Curated OER
Moving and Growing
Students work with a partner to brainstorm a list of as many human body parts as possible. Using that list, they circle any one of those that are bones. They are shown a model of the human skeleton and practice locating various bones. ...
Curated OER
Grouping and Changing Materials
Young scholars feel and observe different types of materials. Using the internet, they sort objects based on the materials they are made from and justify their reasons for putting it in a certain category. They identify objects that...
Curated OER
Electromagnets
Learners conduct a series of experiments on electromagnets. In this physics lesson, students build their own electromagnet and explain how it works. They determine the factors that affect its strength.
Curated OER
Lenz's Law
Students conduct a series of experiments on electromagnetic induction. In this physics lesson, students apply the right hand rule to determine the current direction and electromotive force. They test Lenz's and Faraday's law by observing...
Curated OER
Eating Through the Metric System
Seventh graders convert measurements in recipes to metric measurements and prepare the food items. They create a metric measurement cookbook.
Curated OER
The Elements
Students watch video, The Elements, research information about elements using both the Internet and CD-ROM program, and create atoms out of gumdrops and licorice.
Curated OER
Rising Water!
Young scholars observe water change from a liquid to a gas state when heated and then return to its liquid stage when cooled. They learn that gas molecules move faster than liquid molecules. They discover physical properties that...

The Invention of Faraday Cage
Young scholars demonstrate how Faraday's cage work by building their own electroscope. In this physics lesson, students explain how Faraday's cage work. They cite several applications of this principle in the real world.
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...
Curated OER
Scouting for Circuits
Fifth graders investigate electricity and how it used in a circuit to be useful energy. They also use this investigation in order to understand how energy can change forms and still be considered useful if put into the right form.
Curated OER
Speaker
Students construct a sound speaker. In this technology lesson, students use magnet wires, a phono plug, a battery, and sandpaper to construct a homemade sound speaker.
