Turn Up the Volume
Measuring volume can be a mystery for 5th graders, but this hands-on activity gives the gift of discovery. The volume of simple rectangular solids and irregular shapes are calculated through various methods including displacing liquid in...

Density of Water
We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity.

Determining Densities
Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...
Curated OER
Length, Weight and Measures
Students complete measurement activities. In this measurement lesson, students watch online clips about measurements. Students view items and discuss taking measurements of them. Students discuss what units of measurement and equipment...

Come on Down!
What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...

Density: Sink and Float for Liquids
We don't think of liquids as floating typically, but a quick look at any oil spill tells a different story. Lesson explores various densities of liquids and why this fact is important. After observing the density variation, scholars...

Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting instructional activity, scholars explore buoyancy and the properties of air and water. They test...
Curated OER
Water Conservation
Students explore types of water reserves. In this water conservation lesson, students brainstorm ways water are used in their homes. Students use a graduated cylinder to simulate the amount of water on Earth and the amount that humans use.
Curated OER
Matter
Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson plan, students complete 8 lessons to learn about matter, its states, and how to measure matter.
Creative Chemistry
D-Block Ions as Catalysts
In this catalysts worksheet, students use transition metal ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.
Curated OER
Porosity
Students predict and test the porosity of sediments with particles of different sizes. They name two objects that they think has pores. Students define the term porosity and pores. They comprehend that an aquifer is the porous rock...
Curated OER
Salinity
Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.
Curated OER
Get Down With Density
Students define density and observe that things that are less dense than water will float. Students find the density of copper, iron and aluminum
