More on Temperature and Solubility
High schoolers discover how temperature effects the solubility of solutes by experimenting with a range of temperatures. They develop skills for observing, inferring, measuring, comparing and contrasting.

Chemistry: The Case of the Sunken Ice Cube
Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...
Curated OER
Oranges and Stopwatches
Learners begin to recognize that objects have many measurable attributes. They examine how to identify and accurately measure attributes of common objects. Also Students report their measurement findings.
Curated OER
Marshmallows
Third graders estimate the volume and mass of one marshmallow using appropriate standard units. They design and carry out an investigation to find the average of volume/mass of one marshmallow.
Curated OER
What is a Pico?
Students label objects in their classroom based on mass and volume using the metric system. They examine the relationship between the numerical value and the corresponding metric unit.
Curated OER
Nature's Air Conditioner
Students observe the process of transpiration in leaves. They measure how much water a leaf gives off in a 24-hour period, calculate the volume, and answer discussion questions.
Curated OER
The Same But Different
Third graders observe a frozen container filled with ice and discuss what happens when the ice sits out in the room. They practice measuring the mass and volume of the ice, watch as the frozen container is placed in a warm water bath to...

The Weight of Things
Students explore weight. In this math lesson, students predict which item weighs more and discuss how they arrived at their decision. Students weigh several items to determine which weighs more.
Curated OER
GUM: More, Less, or the Same?
Students confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.
Curated OER
Perplexing Perimeters
In the process of constructing their own "rulers" Students develop a sense of the size of a centimeter and meter. Students select the appropriate "ruler" for the tasks. Finally, 3rd graders calculate the perimeter of objects using...
Curated OER
Floaters and Sinkers
Fifth graders define density as the amount of mass per volume a material contains, compare the densities of several types of materials, especially those that sink in water compared to those that float. They use two different methods to...
Curated OER
Float or Sink?
Learners examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph plotting...
Curated OER
Graph the Density of Fruit
Fifth graders review the definition of mass and volume. They calculate and graph the density of various types of fruit while working in groups on a spreadsheet program. They look at how size of the fruit can be similar but the weight is...
Curated OER
Average Looking
Students use measurements of their classmates to find the average (means and modes) of their facial features. They use their findings to create a three-dimensional "class head." Examples and assessment materials are included.
Curated OER
What Do Concentrations Mean?
Pupils investigate the concept of climate gases and practice using the appropriate measurement terms. The lesson includes information that is used by the teacher to conduct class discussion or as a source of background for students.
Curated OER
Angles: Angles, Angles, Everywhere
Students estimate and accurately measure the size of angles communicate with the appropriate geometric terms and symbols to describe and name angles, lines, line segments, rays
Curated OER
The Great Cover Up!
Students use non-standard measurement tools such as body parts, beans and counters to find the area of shapes drawn on the floor. They continue to determine the area of other objects in the classroom.
