Making Paper
Students create paper by adding a few small scraps of paper into the blender pitcher and adding just enough water to thoroughly soak paper.
Curated OER
Watch It Slide!
Students work together to examine inclined planes. They create a plan to raise rocks to build pyramids. They discover the changes that occur when the angle is increased or decreased.
Curated OER
Away You Go
Students build Lego cars which have two different types of tire surfaces. They roll them down ramps that have both rough and smooth surfaces to determine how friction affects the car as it rolls.
