Writing an equation of a line is as easy as m and b. A lesson presentation gives individuals different strategies for writing equations of lines. Some items provide a slope and a point while others provide two points. Whatever the given,...

Students conduct research on historical population changes in the U.S. They conduct Internet research on the Historical Census Data Browser, create a bar graph and data table using a spreadsheet program, and display and interpret their...

Middle schoolers describe plotting functions on the Cartesian coordinate plane. They solve functions on paper and using an online tool to plot points on a Cartesian coordinate plane creating lines and parabolas.

Students solve volume problems. In this geometry lesson, the class watches a video about clean water (link provided) and individuals compare the volume of different prisms, including an actual drinking glass. Extension activities include...

Third in a set of lessons regarding reservoirs, dams, and hydropower, this involves a two-day hydropower plant simulation. Collaborative groups build, maintain, and finance the plant. The transparency of the reservoir setup can be...

Make sure your scientists are reporting their work effectively by providing them with a reference for their lab reports. The first few pages of this resource detail each element of a lab report, and the last few pages provide an example...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Hate to vacuum, but enjoy using a vacuum pump? Explore a lesson that starts with a demonstration of boiling water at various temperatures by using a vacuum pump. Then scholars design their own experiments to measure vapor pressure and...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Want my name and number? It's 6.0221415 times 10 to the 23rd, and my name is Avogadro. Providing nine different activities, experiments, and labs, this lesson keeps Avogadro relevant to your class all year long. 

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

Covering both permeability and porosity, scholars perform a hands-on experiment testing various soil types. The material includes a pre-lesson plan worksheet to help focus pupils on the task at hand. 

Agriculture is truly a math-based profession! Help the dairy farmer determine the supplies needed to complete his barn. Using given dimensions, learners build equations and use units to determine the correct amount of materials.

Obesity is a worldwide concern. Using survey results, learners compare local BMI statistics to celebrity BMI statistics. Scholars create box plots of the data, make observations about the shape and spread of the data, and examine the...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...

Here is a (great) lesson on using parentheses! The task requires the expression of ages using algebraic expressions, including the distributive property. Pupils use their expressions to determine the individual ages.

Bring your pupils in the loop with while loops. Scholars learn how to modify conditional statements to produce while loops in the 14th lesson of the series. They use flowcharts to understand loops and then program some examples of...

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...

Show your classes the importance of mathematics in something as simple as bicycle design. The final lesson in the six-part STEM series has each group research a different aspect of the bicycle. Learners use mathematical formulas, linear...

Learn about polymers while playing with shrinky dinks. Young scholars create a shrinky dink design, bake it, and then record the area, volume, and thickness over time. They model the data using a graph and highlight the key features of...

Floating fragments of elodea can grow even without roots. Young scientists use eldoea plants to observe the oxygen production from photosynthesis. They study the difference between having access to high amounts of light and low amounts...
