How do simple machines make work seem easier? How do they change the force we put into them? How can changing the direction of a force help us? Explore each of the 6 simple machines using hands-on activities. Calculate how much they multiply force through experimentation or direct observation. Investigate each of the 6 simple machines, levers, ramps, pulleys, wheel & axles, screws, and wedges.
Genetics & Heredity
What's the difference between DNA, genes, and chromosomes? How do our genes results in different traits? What's the difference between mitosis and meiosis? How can a Punnett squares worksheet help me track genes and traits in organisms? Lab activities will help answer these questions.
Sound & Waves
This collection of hands-on activities covers the main concepts for studying waves and sound. You'll use different vibrating objects and see how each makes sound. Investigate wavelength, speed, frequency, amplitude through building a variety of models. Compare two types of waves transverse and longitudinal (compression) waves using a hands-on approach. Determine how pitch is related to frequency and see how differently-sized objected vibrate with different frequencies and therefore make different pitches or notes. Learn a few ways of amplifying sound and investigate how humans locate sound in three dimensions.
Light, Optics & Color
What do pinholes teach us about optics? What is the difference between convex and concave lenses? How do you measure the focal length of a lens? What are the 3 primary colors of light and how do they compare to those of pigment? Lab activities dig into these questions and are great for classrooms or homeschool.
