Students are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.

Students hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.

Second graders explore states of matter when they change a liquid to a solid. Working students make ice cream in a zip-lock bag.

Seventh graders examine the functions and roles of membranes in cells. They discover the differences between plant and animal cells.

Sixth graders analyze and compare a cell's tissues, organs and organ systems. They watch a video reviewing the body systems and design poster boards showing their functions.

High schoolers explore the relationship between pressure and vessel diameter. They are given an open-ended design challenge in which they engineer their own remote repair device. Students see a model that represents how elevated blood...

Students study the difference between physical and chemical properties. They also discuss changes in matter, known as physical and chemical changes. They observe and discuss several demonstrations of both physical and chemical changes

Students work on The Six Solution Problem, which is a logic problem assuming that the student knows some basic reactions and solubility rules.

Sixth graders explore chemical and physical changes. In this lesson about chemical changes, 6th graders observe various items and changes that occur at certain times. Students determine what change took place and observe the change....

Fifth graders are introduced to the concepts of weathering and erosion. In groups, they rotate between different stations to discover how each process effects different landforms. To end the activity, they discuss each change in the...

Seventh graders analyze and identify the role of the cell membrane and nucleus. They create flash cards to help them review cell structures. They also compare plant and animal cells.

Students explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces by measuring the distance that a...

Fourth graders study the functions of the human eye and how it processes information.

Third graders recognize that different materials have different properties which can be observed such as texture and bouyancy, and compare and contrast, through observation, ability of some objects to float because of action of...

Eighth graders, in groups, explain the difference between physical and chemical changes.

Students track and record data on the Sun's position in the sky and on the output of a solar panel tracking the Sun. On a second day, students graph and analyze the data to identify relationships between (1) the time of day, (2) the...

Students discover the law of conservation of mass though experimentation.  In this chemistry lesson, students experiment with acid - base indicators to determine the presence of carbon dioxide. Students complete the labs with...

Students create a PowerPoint presentation on the information they research about the ice cores and what they tell us about Earth's past. In this ice core lesson plan, students research radioactivity, air pollution, sodium, snowfall...

Students participate in a lab activity in which they extract DNA from a strawberry. After mashing the strawberry into an even, smooth puree inside a bag, they add extraction buffer and mix the strawberry with the buffer. They filter...

In this chemical reactions learning exercise, students review the law of conservation of mass, the principle of definite proportions, and balancing equations. This learning exercise has 3 problems to solve.

Students study chromosomes and how molecular half life affects them.  In this chromosome lesson students complete several lab activities on calculating half life, and cracking alkanes. 

Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...

Students understand there are healthy and not healthy food choices. In this food pyramid lesson, students learn to make healthy choices by playing a traffic light game. Students recognize raw foods from the farm may not be ready for...

Students enjoy a hands on activity to understand how and why magma moves inside volcanoes.
