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.

Students explore the size of a kilometer and the time it takes to cover this distance. They develop a concept of a km. They measure a distance of 1 km and the time taken to cover it.

Students set up a classroom currency exchange and explore the idea of bartering to get what they want. They create a monetary unit that is based on fractions and multiples of a standard unit, and compare this system to the U.S. monetary...

Students identify the physical needs of animals and if plants need the same things as animals. They conduct an experiment to see if plants need light and water to grow. They compare the growth of the plants exposed to the different...

Students study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.

Learners record the daily outdoor temperature as well as the number of minutes of sunlight per day over a determined period. They calculate the average temperature and minutes of sunlight per day and post their data on the project website.

Third graders examine the concept of work as the movement of an object through a distance. They define gravity and determine what type of work is caused by gravity. They measure how far an object is moved by a force. They make a...

Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.

Students plant seeds and watch them sprout. Once growing plants are placed in different conditions and students record data about their growth. They graph the data.

Students make either and insect or a spider using materials their teacher provides. They then draw of picture of their organism and defend why it is either a spider or an insect.

Third graders experiment with beakers of water and balloons to measure the volume of the gas in the balloon. They determine ways to change the volume of air in the balloon which changes its size but not its physical state. By heating the...

Learners discuss meaning of pitch, listen for different sounds in classroom, hallway, and outdoors, and listen to sounds played on piano and on computer to determine high or low pitch.

Students simulate hibernation with their stuffed animals. They predict the length of time of hibernation and type their math journal entries about sorting, graphing and draw pictures. They read bear hibernation stories.

Students create terrariums (mini rainforests). They observe and discuss the life processes that occur in their terrariums and how changes in these processes affect the plants and organisms inside. They collect and graph data and present...
