The objective of this activity is to find the percent of the area of a two squares overlapping. Mathematicians find the ratio of area for the part that overlaps to the rectangle formed. The final answer is a percent as a rate per 100....

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Explore logarithms and logarithmic regression. Young mathematicians first learn about inverse functions and about the logarithm function family. They take their newfound knowledge to use logarithmic functions to model situations and...

Litmus paper, why so blue? A chemistry lesson includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this lesson: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium with cobalt...

Avoiding lab safety rules will not give you super powers. The lesson plan opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a mixture and...

Welcome learners to the world of algebra. Use a lesson that poses a situation involving the profit from creating greeting cards to teach about algebra. It requires scholars to use linear functions and inequalities to solve problems.

Investigate exponential growth and decay. A set of six activities has pupils collecting and researching data in a variety of situations involving exponential relationships. They model these situations with exponential functions and solve...

If you need a way to assess the concepts in your physical science class, use an extended set of worksheets as a midterm or final exam. It includes questions about density, physical and chemical matter, speed and velocity, weight and...

During this hands-on activity, young chemists build molecular models based on the Lewis dot structure before studying valence shell electron pair repulsion theory. 

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. 

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...

Students experiment to determine the effect of light on cyanobacteria movement. They graph the data of the experiment for further analysis. They watch a time-lapse video of cyanobacteria motility at a NASA website.

Sixth graders study heat, temperature, and heat transfer. Using probeware, the teacher demonstrates boiling points. Students participate in experiments and record the beginning and ending temperatures and mass of objects. After...

Learners compare the basic needs of plants to the basic needs of democracy. In this democracy comparison instructional activity, students complete a worksheet on what happens to a plant that's not nourished. Learners draw a correlation...

In this airplane worksheet, students compare the mass of an airplane to the mass of a paper clip airplane to see if the mass determines the best flight. Students complete 5 trials for each.

In this paper helicopter worksheet, students design and experiment making a paper helicopter to explore how some things fall and how varying the size of the rotor blades affect the way a helicopter spins.

In this expressions worksheet, students solve and complete 16 different problems related to various expressions. First, they define each of the listed terms and know each given property. Then, students state the order of operations and...

In this nature of science and measurement worksheet, students answer 30 questions about experimental design, pure science vs. applied science, density, metric conversions and dimensional analysis.

Students design an experiment to investigate how objects with different masses fall. For this physics lesson, students predict how these objects will fall in a vacuum tube. They write a report explaining experimental results and conclusion.

Students examine how seeds germinate in a culture.  In this germination lesson students germinate seeds in gelatin and observe the growth of the plant.

Students conduct an experiment. For this movement lesson, students see how far a marble will roll after coming down a ramp. The students change the height of the ramp to make it roll faster and record their results.
