Curated OER
Will It Sink Or Float?
Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.
Curated OER
i-Density Crisis
Eighth graders determine the density using mass and volume. In this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known density.

Revised “Understanding Nutrition” Activity
Students evaluate their current food choices. In this health science lesson, students test different drinks to rate the amount of Vitamin C content. They discuss results in class.
Curated OER
Newton's Laws and Rocketball
Students investigate Newton's Three Laws. In this Newton's Law activity, students write the laws in their own words. Students then do an experiment with a ping pong ball. Students drop the ball from a set distance and record their...

Vision and Optics: Light and Lenses
Students gain a conceptual comprehension of the functioning of the Human Eye in relation to optics and optical vision correction. They explore optics with light sources and various lenses, relating these to visual acuity, accommodation,...
Curated OER
A “Scientific” Approach to Buying a Car
Students examine what it takes to purchase a car and the resources out there to help find what you are looking for. In this scientific method lesson students complete different problem solving situations.
Curated OER
Observations and Inferences
Learners observe how to distinguish observations form inferences. For this examining inferences lesson students list observations relating to the activity and discuss the importance of them.
Curated OER
Chemistry: pH Probe
Students conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases. Finally,...
Curated OER
Orbit, rotation, revolution of Earth
Eighth graders define orbit, rotation and revolution. They demonstrate the orbit, rotation and revolution of the Earth. Students identify the types of measurements and the instruments that used for orbit, rotation and revolution. They...
Curated OER
Heat And Heat Transfer
Learners role play molecules in a container as the container is heated to develop a definition of heat and temperature. They also observe demonstrations of conduction, convection, radiation, and phase transfer. Using these observations...

Where Did the Water Go? An Investigation in Scientific Methods
Middle schoolers view a teacher demonstration that prompts them to solve a problem using the scientific method. In this scientific method activity, students guess which cup has water and are presented with a conundrum when the water does...
Curated OER
Day Two: Generating New Questions
Students investigate buoyancy by participating in a lab experiment. In this density lesson, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Students analyze which items float and do not while...
Curated OER
The Causes of Differences in Density
Students explore how density changes. Students read an article on density. They observe a ball and ring demonstration and discuss the outcome. Students draw models of the demonstration and explain what happened.
Curated OER
Buoyant Force
Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...
Curated OER
Three-Hole Bottle
Students participate in an experiment with a 2-liter bottle. They develop their own hypothesis about what they believe will happen when certain items are tested on the bottle. They discuss results.
Curated OER
The Great Volume Exchanger...or the Magic Matter Maker ®
Students pour water into a "magic" box and examine how it comes out with a much larger volume of water. They, working in small groups, design a volume exchanger and explain its design to the whole class.
Curated OER
Investigating Density: Heavy Ice
Students end up learning the formula for density and calculate the densities of various materials, and predict if they sink or float.
Curated OER
Why is the Average Temperature Greater on Venus than on Mercury?
Middle schoolers examine the reasons why the temperature is higher on Venus than on Mercury. In groups, they analzye both planet's atmospheres and determine the rate of global warming on each. They use the internet to research the...
