Curated OER
Weightlessness
Students use a coffee cup to demonstrate weightlessness. After a lecture/demo, students read an article on free-fall. They perform a simple experiment which helps them explain the concept of weightlessness.

Paper Clip Sailing
Students explain that some things can float on top of water because of what we call "surface tension." They see that if something happens to disturb these water molecules from tugging on each other, the skin-like surface breaks up.

HOW FAST DO SEDIMENT GRAINS OF DIFFERENT SIZES SETTLE?
Students conduct an experiment using sand, a jar, and a paper clip to analyze the effects of different kinds of sand vis a vis its sediment. They graph their findings and analyze for factors of size, shape, and density.

Waterskiing in Circles
Students discuss and give examples of Newton's three laws. They then answer questions in reference to Newton's three laws. One example of the questions that students answer is: A water-skier typically uses a 75 foot tow rope. The skier...

Changing State
Students investigate the cooling and heating of water. In this online science experiment lesson, students work in groups to make predictions regarding freezing and boiling points and then test those predictions as they complete the...
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
Air Pressure
Students investigate the basic principles of air pressure. In this experimental lesson students use materials to create several different experiments that help to explain air pressure and friction.
Curated OER
Circle of Pong
Young scholars, in groups, use given materials to devise a way to deposit a ping-pong ball into a paper cup that is located in the middle of a 6-foot diameter circle, while standing outside the circle.
Curated OER
Free Up the Ketchup!
Students, in teams, use given materials and their knowledge of Newton's First Law to create a device that will remove a sticky ping pong ball from a 16-oz. cup (which represents ketchup stuck in a bottle.)
Curated OER
CO2 and Air Pollution
Seventh graders observe and test for the presence of carbon dioxide gas. They compare concentrations of carbon dioxide gas and conclude high concentrations of carbon dioxide gas are unhealthy for human beings.
Curated OER
Building Bridges
Students identify the different types of bridges. Using the internet, they research information on how they are built by completing a scavenger hunt. Locating a specific area, they determine which type of bridge would be appropriate and...
Curated OER
Volcanic Unrest
Students explore the Ring of Fire. In this volcano instructional activity, students discuss active volcanoes in the world and explore viscosity as they participate in a hands-on classroom activity.
Curated OER
Downhill Discoveries
Students are involved in hands-on activities to determine how course conditions affect bobsled, luge, and downhill ski races.

Investigation 7 - Rubbing Objects Together
Third graders investigate rubbing two objects together to produce heat.
