Students conduct an experiment. In this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...

Young scholars conduct a series of investigations on the unique properties of water. In this general science instructional activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

Students investigate the carbon dioxide content of different sodas. In this chemistry instructional activity, students explain why PET containers are preferable than HDPE for soda bottles. They collect data and graph them.

Students identify and analyze the concept of density using the formula, density equals mass divided by volume. They review the differences in salinity levels of the ocean and note that the changes in density are caused by wind and...

High schoolers explore the microstructure of the ocean by analyzing graphs created by Dr. Mike Gregg of the University of Washington Applied Physics Laboratory during the EPIC 2001 research cruise on the Ronald H. Brown NOAA vessel.

Learners conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...

Young scientists build on their previous knowledge and apply it to coronal mass ejections. By plotting the path of two different coronal mass ejections, they develop an understanding of why most don't collide with Earth.

A neat handout immerses learners in the history of canoe making. After reading, small groups of mini engineers work to craft a canoe that will not be immersed! This is an ideal exercise in engineering design for your STEM curriculum or...

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final lesson in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter before performing...

Students form hypotheses and carry out an investigation in order to answer a central question: Does soap float? The focus of this lesson is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.

Students explore the effects of population growth in Arizona.  In this history lesson, students work in small groups to create a "perfect" city. Activities include examining the Arizona census results then discussing the importance...

Eighth graders determine the density using mass and volume. In this science lesson, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of known...

Students work with a partner to record observations on various materials. Working together, they calculate the mass and volume of each material and then combine them and shake them for a period of time. In their journals, they record...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly instructional activity, learners use scientific...

Students examine buoyancy.  In this density lesson plan students form a hypothesis, collect data and draw a conclusion using the data. 

Students investigate density. In this density lesson, students conduct an experiment using food coloring. Students observe the differences in mixing food coloring in water and oil.

Students explore chemical reactions. In this chemical reaction lesson, students conduct an experiment observing chemical reactions.

Young scholars define specific waste materials that could be used as aggregate in concrete. In this aggregate and waste lesson plan, students brainstorm on how to incorporate waste in construction and define different aggregate materials.

Students use water, beakers, hot plates, paper dots, and goggles to participate in a hands on activity where they see how a convection current creates wind. In this convection current lesson plan, students participate in a hands on...

Scientists classify everything from the smallest cells to the largest galaxies, but how do they decide on a classification system? Scholars use 40 pictures of galaxies taken by the Hubble Space Telescope to sort and try creating their...

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

Students examine the differences between air temperature and ground temperature.  In this investigative lesson students find NASA data on the Internet and use it to create a graph.
