Matter, Matter, Everywhere!
Eighth graders make inquiry about the existence of matter. A definition of the word is needed before students can engage in various activities. The application of knowing about matter is done in the working of experiments.

Surface Friction and Wear Characteristics of Common Materials
Students identify the factors affecting friction. In this physics lesson, students construct their own rocket car and race them. They graph the average speeds and discuss how lubricants affect friction between rubbing surfaces.
Curated OER
Density
Young scholars explore the meaning of density. In this density lesson, students use interactive whiteboards to review definitions regarding density and compare the density of selected objects.

Parachutes: What Affects a Parachute
Students create a simple paper parachute. In this parachute design lesson, students examine the effects of the wind and make napkin parachutes.
Curated OER
Air Expansion and Contraction
Pupils observe that air exerts pressure, that heated air expands and that cooled air contracts. After the demonstration, students engage in a question and answer session about what they saw.

WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
Curated OER
The Pressure's Off
Students investigate air pressure with four hands-on activities. They observe experiments by viewing Take a Look 2 #21.
Curated OER
Science: Liquid Matter
Second graders examine the properties of liquids and their classifications. They compare and contrast cups of different liquids and record their findings in journals. Students observe how liquids flow at various speeds and that unlike...
