Changing the Density of a Liquid - Heating and Cooling
During a unit on density, pupils ponder whether or not temperature affects this property. By carefully inserting blue cold water and yellow hot water into a room-temperature sample, they will see the answer. Make sure to have done the...

Changing the Density of a Liquid - Adding Salt
Fourth in a set of several little lessons on density, this one compares the density of fresh and salt water. First by demonstration, and then by a hands-on activity, learners find that adding salt increases the density, as is evidenced...

Investigating the Line
Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...
Curated OER
Applied Science - Physics Pre-Lab
Students observe fluid motion. In this Physics lesson plan, students explore the principles of Pascal, Archimedes, and Bernoulli. Students list their experiences with fluid movement.
Curated OER
What is Matter?
Students investigate what matter is and how it changes states. In this physical properties instructional activity, students examine the vocabulary database and identify the characteristics of the three phases of matter. Students...

Motion in Fluids
Young scholars explore physical science by participating in a science activity. In this liquids lesson, students discuss how fluids can be affected by motion unlike solids. Young scholars define other scientific vocabulary terms and...
Curated OER
Water
Learners conduct a series of investigations on the unique properties of water. In this general science lesson, students explain what causes water's surface tension. They explain the different stages in the water cycle.
Curated OER
Icebergs Ahead!
Students examine icebergs and how they are suspended in water, why ice floats, the melting process of an iceberg, and the floating behavior of ice compared to that of a cork through a lab activity.

Determining Acids and Bases
Students use purple cabbage indicator to test five know substances for acidic/alkaline balance. They discuss the safety precautions required both inside and outside a lab in handling acids and bases.

Hitler's Lost Sub
Students watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.
