Molecular View of a Solid
Why are solids, well ... solid? Take a peek inside a solid substance with an easy-to-use interactive. Science sleuths examine the motion and position of the atoms that make up a solid before drawing conclusions from their observations.

Curious Crystals
Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

Heat and Matter
Students explore liquids and solids by conducting in class experiments. In this matter activity, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter...
Curated OER
Science- Unit on Matter- Solids
Second graders identify and describe properties of matter.
They identify three forms of matter- solids, liquids, and gases with 100% accuracy.  The student describes the properties of solid objects.
Curated OER
Matter
First graders study and define matter.  They observe and identify states of matter along with common attributes and study how matter can change form or change its state depending on temperature.

Changes In Matter, "The Big Chill"
Third graders investigate why ice cream does not go through any chemical changes when it is exposed to physical changes. They describe the three states of matter in either written or verbal form. Then students experiment with ice cream...

Temperature and Bounce
Take part in a fun experiment and hold an impromptu bouncing contest with your class. Young scientists heat and cool balls before bouncing them to determine whether temperature changes affect how they bounce. The set of...
Curated OER
Science- Unit on Matter- Liquids-
Second graders discover that everything is made of matter. they determine the properties of liquids and that like solids, liquids can be grouped or classified according to properties or qualities. they assess that solids have a definite...

Ooblek
Students demonstrate the three states of matter. For this matter lesson, students read Bartholomew and the Ooblek. Students create "ooblek" and discuss what state of matter it is.

Matter Matters: Solids, Liquids and Gases
Scientists participate in a variety of hands-on experiments in this ten-day unit on the three states of matter. Lessons incorporate literature, a-v materials, and poetry to help young scholars differentiate between solids, liquids and...
Science Friday
Mineral Madness
Science does not need to be as hard as a rock. Pupils test 10 different minerals to determine their properties. The learners observe luster, streak, hardness, and fluorescence for each specimen. Afterwards, they compare and contrast the...
