Activity #5 'Empty' Bag?
Young scholars review that air is a form of matter. They investigate how air takes up space. Pupils comprehend that they cannot see air, it takes up space and has mass, therefore it is a form of matter. Students investigate how to...

How Do You Know There is Air in a Bag?
Fourth graders explore air as a material substance. Through experimentation and discussion, they explore how air can be classified as a material substance. Students write three examples proving that air is a material substance in their...
Curated OER
Weightlessness Demonstration
Students explore the concept that free-fall eliminates the local effects of gravity. They discuss what an Earth-orbiting spacecraft experience is like as well as the terminology of weightlessness. Their lab experiment commences.
Curated OER
Weightlessness
Students predict the behavior of coffee in a cup while it is dropped during a demonstration. They relate their observations to the weightless conditions that astronauts experience in space and discuss the concept of free-fall.
Curated OER
Liquid Crystal IR Detector
Middle schoolers experiment with one method of detecting infrared radiation. They simulate the detection of infrared radiation using a liquid crystal sheet.
Curated OER
Cosmic Collisions and Risk Assessment
In groups, learners create their own scientific impact experiments using ordinary materials, and observe and measure results with a variety of impacting bodies and velocities.
Curated OER
Drop Zone! Design and Test a Probe
Students work together to develop their own parachuting probe. They test it and record the results. They simulate other experiments that are going to be carried out by the Huygens probe.
Curated OER
Radish Seed Garden
Fifth graders explore the effects of overpopulation in an ecosystem while applying the scientific method. They discuss overpopulation and its meaning. Students as an organism competes for space in an overpopulated area. They plant...
Curated OER
Detecting Magnetic Materials in "Martian" Soil
Students simulate some of the Pathfinder experiments by devising methods of collecting and measuring magnetic substances in pseudo-Martian soil. The efficiency of each of the methods used to collect materials is evaluated in this...
Curated OER
Oxygen vs. Air Pressure
Students conduct an experiment to determine if water level is affected by a change in oxygen level or air pressure.
Curated OER
an Explorative Journey Through the Solar System
Students, in groups, research a planet from our solar system. They create Styrofoam models of the planets and place the planets on a correct distance scale from the sun.
Curated OER
Current Interactions
Students design an experiment to see how wind, temperature, and salinity work together to influence ocean currents and present it in a report format. They explain to their classmates how experiment findings relate to ocean currents.
Curated OER
Hurricanes
Students state and directly experience two laws of Physics (Law of Gravity, Law of Centrifugal Force) that affect weather. They explain the observations made when using the "hurricane machine" and relate them to other events and phenomenon.
Curated OER
Physical and Chemical Changes
Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science lesson, 6th graders complete 6 experiments about chemical and physical changes. Students examine the processes of...
Curated OER
Electromagnitism Applications
Students experiment on magnets and electricity. In this physics lesson, students determine what factors affect the strength of a magnetic field. They design an experiment to determine how electromagnetic field strength varies with distance.
Curated OER
Warm and Cold Air
Students examine what happens to air when it is heated or cooled. They conduct an experiment using bottles and balloons, record and discuss their observations, and write a hypothesis.
Curated OER
Oxidation And Corrosion
Students sort tarnished metals by type and experiment with different cleaning solutions and techniques to restore them to their natural color and shine.
Curated OER
NIH Image Fault Investigation
High schoolers use the image processing software, NIH Imageto view images of Earth taken from the space shuttle. They use NIH Image to determine the length of the visible portion of the fault, where it has ruptured the Earth's surface.
Curated OER
Wind
Fourth graders watch an experiment that demonstrates the causes of wind. They design and make an original weather craft.
Curated OER
Understanding Lava Layers
Seventh graders trace the lava flow of an erupting volcano. In this earth science lesson, 7th graders experiment using baking soda and vinegar. They record and share their observations.
Curated OER
Earth History Part II
Eighth graders hypothesize what caused the break up of continents. In this earth science lesson, 8th graders study about the events that took place during Mesozoic and Cenozoic Era. They reconstruct a supercontinent and report their...
