Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson can stand alone, but is best used as part of the...

Help young scientists piece together the theory of plate tectonics with this comprehensive collection of materials. Whether your are looking for worksheets, hands-on activities, or assessments, this resource has everything...

Cells of different organs have unique cell functions. Learn how cell functions vary depending on their roles in the body using an inquiry-based activity. Scholars analyze the cell structure to make comparisons to its functions, allowing...

Students examine the needs of trees and plants. In this forest ecosystem lesson students use seedlings to investigate the basic necessities of plants. They discuss the consequences of these basic needs not being met.

Students examine soil. In this earth science lesson, students define and describe weathering and erosion as it relates to soil. Students compare and contrast potting soil with forest soil and complete a science observation worksheet.

Students investigate different purposes for manipulating DNA. After reviewing the structure and functions of DNA, students explore topics related to the use or manipulation of DNA and the potential benefits and problems, later making a...

Students review data from a 24-hour dietary recall to gain a practical understanding of information regarding energy intake and macronutrients.

Students review what they already know about DNA. After reading an article, they discover a new technique to map the course of evolution. In groups, they create ways to present this material to younger children and research DNA's uses.

Does Newton's Law of Cooling have anything to do with apples? Scholars apply Newton's Law of Cooling to solve problems in the 29th installment of a 35-part module. Now that they have knowledge of logarithms, they can determine the decay...

Young scholars examine animal reproduction by interpreting data and making arguments and then create their own graphs to explore relationships of organ systems. This lesson includes an individual worksheet and a reflective review...

Learners investigate the stripes in sedimentary rocks, using a structure at Petra, Jordan, as an example, and then do a hands-on activity using mixed nuts to illustrate the layering of sedimentary rocks.

Emerging electricians extend mental models of light bulbs and resistors in series and or in parallel circuits to include the connection of photovoltaic cells in arrays. They investigate open circuits, using a DC voltmeter, a light...

Students experiment with solids and liquids. For this mixtures of matter lesson, students combine matter to form solutions. Students hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by having...

Students investigate nature by identifying different plants and trees. In this environmental field trip, students participate in a British Columbia expedition in which they identify cedar, pine, hemlock and Douglas fir trees. Students...

Pupils view a video to explain the meaning of friction. In a hands-on experiment using gelatin, students test the effects of lubrication on friction. They complete a worksheet imbedded in the lesson to describe their observations.

Students participate in a class discussion about wildfire and urban interfaces as well as risk of wildfire in the area in which they live. After reviewing a wildfire/urban interface fire safety checklist, a walking field trip is...

Learners examine the effects of temperature and density in ocean currents. In this density lesson, students explain how coastal climates are impacted by ocean currents. They investigate how the ocean currents are affected by temperature...

Tenth graders examine how energy is lost through different trophic levels.  In this trophism lesson students construct a food web and view a video. 

Students sample a site with low human impact, one with moderate human impact, and a third with high human impact. Students chart the data for each site and then compare the sites and discuss.

Students collect samples of pond water, dried grass, and soil in a jar. They predict the order of ecological succession in their pond water cultures. They compare their expected results with their observed results.

Students use a shoe box to simulate what happens when candy gets between your teeth. In this teeth brushing lesson, students explore the importance of brushing your teeth. Students listen to Brush Your Teeth Please. Students recognize...

Students explore water as it changes states of matter. In this physical property lesson, students use observation, measurement, and communication skills to describe changes in water as it goes from a solid to a liquid and back again.

High schoolers examine tidal currents.  In this tides lesson students describe how the tides affect lives and explain why it is important to monitor them. 

Students discover characteristics of each of the three states of matter: solid, liquid and gas.
