Two Source Interference
The paths of waves generated from two different points are shown here on a sequence of slides. The lengths and directions are labeled, step-by-step. Finally, path interference is shown along with the calculations that your physics...

Seeing Interference Fringes with a Telescope
Learners construct an interferometer using a simple telescope. In this physics instructional activity, students explain how light waves create the fringe patterns. They observe patterns made by different objects in the sky and compare them.

Gumdrop Crystal Models
A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

Food Chains: Simple or Complex?
Students explore the relationships within the food chain between plants and animals. They construct modules of food chains, keeping them simple and not complex. They focus on what the animals eat and not on what eats it.

Build a Weather Vane
Students construct a weather vane using their knowledge of some geometric shapes. In this weather lesson, students work in pairs to create a weather vane in order to measure wind direction. Students follow precise directions to ensure...

Newspaper Weather
Pupils use their knowledge of the weather to evaluate information from the newspaper. They also take this knowledge and construct a weather map predicting the next day's weather.
Curated OER
Flood!
Learners construct a model of a river system. Students observe the effects caused by water rushing through riverbanks and across plains. They predict what will happen when levees are added to the model. Learners test their hypothesis.
Curated OER
The Energy of Waves
In this science activity, students examine the topic in order to solidify knowledge covered in the curriculum using puzzles and creative games.
Curated OER
Uncovering a Signal
Students examine information EEG impulse control. They observe representations of EEG signals. Students use inquiry skills to interpret and analyze the waveforms. They explore how confusion can send control impulses to the wrong...

How Germs Spread
Fourth graders investigate how germs spread in this lesson. They listen to "The Flea's Sneeze" by Lynn Downey and make predictions on why the hog began sneezing. They then conduct an experiment using flour and paper cups demonstrating...
