Animals, Animals, Everywhere
Fourth graders participate in a variety of activities dealing with animal characteristics and classifications in this multi-task lesson. They use graphic organizers, make booklets, and make models.
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...
Curated OER
Faraday's Law of Induction
Students study Faraday's law of induction and the equations that show how to calculate electromagnetic induction. For this electromagnetic lesson students complete several experiments on the law of induction.
Curated OER
Transformers
Students examine how a transformer works and its practical applications. In this electricity lesson students complete several experiments using transformers and generators.

Lesson 5: Designing an Experiment
The intent of this lesson is to introduce young scientists to the steps of the scientific method. To this end, they consider the question, "Which brand of battery lasts longest?" In this case, the experiment is carried out as a class,...
Curated OER
What is an Electromagnet?
Students give examples of electromagnet applications. In this physics lesson plan, students explore what makes electromagnets work. They experiment picking paper clips with it.
Curated OER
Loudspeaker
Learners study the different types of loudspeakers and how they work. In this sound lesson plan students create their own loudspeakers.
Curated OER
Wind Power for Educators
Students explore wind power as a renewable resource. In this wind power lesson students build models of wind turbines and experiment with different changes to see if it increases efficiency.
Curated OER
More Power to You
Young scholars construct a simple galvanometer in order to detect the presence of an electric current as well as determine the amount of the current. Activity is divided into two parts, first part as group work and second as individual.
