Someone stole a diamond-making machine. Who done it? Scholars use forensic science at six different stations to determine the culprit. They analyze fingerprints, use their senses, and complete chemistry experiments to determine the...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

What does viscosity have to do with splatter? An activity shows that the viscosity of a substance is inversely proportional to the distance of its splatter. Learners conduct the experiment by collecting data, graphing, and analyzing...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

Time to witness the effects of sound. Learners analyze different materials to determine their abilities to absorb sound waves. They use free software to monitor the amplitude of the waves to verify results.

n this geometric lesson plan, students define and identify two dimensional shapes based on their attributes. They complete worksheets based on the geometric concepts.

Your young economists will explore the roots of fears about high inflation by learning the effects of rising prices during the world wars and in particular the Great Inflation of the 1970s.

In search of an organic lab that employs real-life techniques and analysis methods? Groups carry out the nitration of methyl benzoate, then attempt to determine the number and location of the nitro groups added to the benzene ring....

How are chemical reactions affected by gravity? Learners explore the phenomenon of effervescence as part of the Christa's Lost Lessons series. They compare findings in an experiment on effervescence to a video of a similar experiment in...

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Learners explore the solar system. In this planets lesson, students learn about the other planets in the solar system. They watch a video clip from National Geographic on the solar system, compare and contrast the planets and create a...

Young scholars decide whether or not there is or has even been water on Mars. They analyze temperature and pressure data from the Pathfinder mission to Mars, and then they analyze images of Mars, interpreting the landforms they see and...

Students calculate ppm and ppb by using unit analysis when given a ratio of amounts. They determine in ppm what constitutes a health risk for a particular toxin given data and whether local health officials should close a lake...

Third graders explore tessellations and the spatial concepts used in creating them.  In this tessellations lesson, 3rd graders rotate, reflect and transform shapes to create tessellations.  Students become familiar with the...

Students explore physical and chemical changes. For this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Students investigate various chemical reactions when creating mixtures in ziplock baggies. For this chemistry lesson, students will recognize various chemical reactions and cite evidence. Safety and assessment strategies are included in...

Students examine the different properties that affect water quality.  In this pollution instructional activity students play a game, complete a hands on activity and computer lab. 

Students analyze and compare laundry bleaches by testing their oxidizing powers. They conduct their lab experiment, compare/contrast their results with other students' work, and complete a worksheet.

Pupils explore linear functions in this lesson when they collect and analyze data as a chemical reaction proceeds. Learners record pressure versus time data and model the data as a linear function. They also examine the concept of slope...

Students investigate how friction affects the movement of a block across surface areas. They test five different kinds of surfaces—smooth surface, wax paper, a paper towel, course, and fine sandpaper. They predict and record the results...

Sixth graders participate in a lesson plan that is about investigating the different layers of the earth and defining how the plates move over the mantle. They engage in a variety of activities and use mathematics to create projects to...

Students build conductivity testers and investigate which solids and solutions conduct electricity. Working in groups, they predict which items will conduct electricity and record their answers on worksheets.

Learners conduct scientific investigation in which they observe glacial effects on landscape, develop and explain their own theories of how glaciers change land, and demonstrate understanding and explain basic motion and force principles.
