Third graders use a Slinky, rubber bands, paper, coins and cups to experiment with weight and its relationship to gravity. They discuss their results and develop a consensus on conclusion statements derived from their experiments.

Students investigate aerodynamics by comparing and contrasting the flight of two gliders. They make prediction and observation charts and test a variety of hypotheses using paper gliders.

Young scholars observe falling objects. They discover the rate of falling is based on air resistance and not the weight of the objects. They discuss how engineers use this type of information to design aerodynamic shapes.

Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...

Students order five weighted plastic eggs in order from lightest to heaviest.

Students explain how conservation of energy applies to roller coasters. In this physics lesson plan, students construct their own coasters according to a specified criteria. They make modifications to their design when necessary. 

Primary learners participate in activities that help them explain how different things are measured. They create their own access number chart.

Students order their classmates from smallest to largest foot length.  In this ordering their classmates from smallest to largest foot length lesson plan, students trace each of their classmates foot.  Students read a story...

Students examine how salt water is more dense than fresh water through experimentation with eggs.

Students demonstrate Graham's Law by observing a gaseous diffusion. After a lecture/demo, students perform an experiment then complete a write up activity which is imbedded in this plan to reinforce what they have observed during the...

In this mixture separation worksheet students problem solve a variety of ways to separate mixtures. After generating solution ideas to separating mixtures of solids prompts on the one page sheet students are prompted to respond in short...

Learners layer different types of soil in water. They are to keep a watch on how the soils react with one another in water.

Teachers, to demonstrate to the elementary student that some gases are heavier than others, this experiment uses Winnie the Pooh and balloons to do just that.

The concept of air resistance is discussed in terms of why a heavier object falls faster than a lighter object when both dropped from the same height. In this discussion and animation, an elephant and feather are used as examples.

Students learn that it is incorrect to believe that heavier objects fall faster than lighter objects. By close observation of falling objects, they see that it is the amount of air resistance, not the weight of an object, which...

Do heavier and lighter objects fall at the same rate? Galileo hypothesized that objects fall at the same rate regardless of their mass. Complete this module to find out if Galileo was right by comparing position-time and velocity-time...
