    Note: Swing time might be more accurately measured by timing five swings and dividing by five if the time is very short.
    Note: The release position of the pendulum can be measure as a height or angle.

    Middle School Lessons
    Atom and Eve
    We will begin with the Hydrogen atom. The students will use a concept map to define and share their information about the Hydrogen atom. They will construct a model of a Hydrogen atom using simple low cost materials.
    Balanced Students
    Students use a hands-on activity to investigate the relationships between weights and the distance of the weights from the fulcrum in a balanced 1st class lever.
    Boom and Fizz
    Boom and Fizz is a thrilling discovery of physical and chemical changes. It combines an engaging teacher demonstration with a hands-on student lab experience.
    Brain Game
    This is a fun lesson that challenges the student’s ability to respond to stimuli that are mixed word/color messages. (Responses to changes in the environment/stimuli)
    Can You Calculate the Speed of Your Pet?
    What is the fastest wind up toy pet? In this lesson students will explore how to calculate the speed of wind up toy pets, average the speeds and identify the correct units of measure of speed.
    Construction and Use of an Accelerometer
    What is acceleration? The students investigate the concept of acceleration by building and using an accelerometer.
    Density Discoveries
    Density Discoveries is a hands on student learning opportunity for students to find the mass, volume, and density of solid matter.
    Domino Effect
    In this lesson, the students will investigate a change from potential energy to kinetic energy and discuss the concept of waves carrying energy.
    EggCELLent Diffusion
    Students observe the effects of diffusion on eggs by observing the change in the egg's size and the amount of liquid substance that remains.
    Evaporation Marathon
    Runners take your mark! This lesson involves a student experiment to see which container will evaporate water the quickest. The lesson invites students to explore independent and dependent variables as part of the experimentation process.
    How Dense Are You?
    How did Archimedes find the gold crown? Students relate how density is a value that describes the material of which the object is made, and is not influenced by the object's shape or size in any way.
    How Fast Is that Rocket?
    This lesson will allow the students to calculate the speed of a falling object using measurements from a falling rocket.
    Pendulum Power
    Students use a pendulum to discuss the Law of Conservation of Energy and the Second Law of Thermodynamics.
    Properties of Waves
    Students observe and investigate wave properties.
    The Grass is Always Greener
    Students will use common grass to observe and experiment with cellular division.
    The Portable Niche
    Students capture an ecosystem in empty film cans placed inside the bottoms of a two-liter bottles. Each created niche is then used to observe distinctive biotic samples.
    Those Vexing Variables
    Students learn to recognize the dependent and independent variables in an experiment by practicing manipulation of variables. They also practice designing experiments that contain the two types of variables.
    What Is The Matter?
    What is the Matter? It’s a solid, a liquid, or a gas. In this lesson, students explore and identify the phases of matter and compare the particle motion in solids, liquids, and gasses.
    What Is an Egg Without its Shell?
    This lab activity allows students to observe osmosis – a cellular process that normally can’t be observed without a microscope. Students follow the steps of the scientific method to observe osmosis in a chicken egg.
