Pupils investigate financial applications of mathematics in this mathematics lesson. They will investigate equations that represent a company’s income, expense, and profit functions and use those equations to identify break even points...

In this voltage, current and resistance worksheet, learners answer 21 questions about voltage, current and resistance. They find the current in batteries, they find the voltage in a resistor and they identify the voltage in circuits.

Students observe that plants need air, food, light, and water to survive.  In this plant biology instructional activity, students observe the growth and development of two plants, one is the control plant and the other is denied...

Tenth graders identify stars based on their line spectra. In this astronomy lesson, 10th graders analyze spectrograph and determine the elements present in the star. They explain the relationship between temperature and star classes.

Scholars find a pattern from a geometric sequence and write the formula for extending it. The worksheet includes a table to complete plus four analysis questions. It concludes with instructional implications for the teacher.

Following detailed directions, teams collect the voltage and current outputs of a photovoltaic cell by adjusting the resistance. Using the collected data, they determine the highest power output. Implications for weather and a large...

Pupils graph data on fetal and infant mortality rates collected by the Centers for Disease Control and Prevention. They identify trends in the data and propose potential causes for the trends.

Students determine the best material from which to make a jacket to keep the body warm in a cold, dry, windy climate. This task assesses the student's ability to perform an entire investigation. In this question the independent...

Students must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."

Learners construct a pendulums and experiment with what variables change or effect the rate at which they swing through an arc. They are assessed on scientific inquiry including the following skills: observation, data collection,...

Students investigate what a controlled group is by creating an experiment.  In this plant growth lesson, students identify the different parts of a plant and discuss what is needed for a plant to be successfully grown....

Pupils are given a problem or hypothesis, they can create a relevant experiment using the steps to the scientific method. They collect quantitative and qualitative observations in scientific experiments. Students identify the difference...

Students identify and implement methods to standardize testing stations that measure solar panel output power. After collecting electrical ouptut data from several solar panels, they plot the current-voltage and power curves. Students...

Students explore how to show evidence of subshells and electron filling on the visual scale. They examine subshell filling and evaluate unknowns based on the atomic emission spectrum. Students design an experiment to identify colors of...

Students investigate the mixing of light. They form a hypotheses to reason why color changes occur and they write conclusions and ask new questions arising from the investigation. Students identify the primary and complementary colors of...

Learners are introduced to basic outdoor survival concepts. They identify the seven basic needs for survival. Students describe the symptoms and treatment for frostbite and hypothermia. They compare and contrast the value of different...

Students explore linear relationships. In this sixth through eighth grade mathematics lesson, students explore the symbolic representation of verbal descriptions of mathematical rules defining the relationship between two variables.

Scholars identify how the TI-89 implements phasors to perform sinusoidal steady-state analysis. The focus is on how to enter and display complex numbers. They also show how a typical steady-state application how to use the Numeric Solver...

Learners discuss what plants require in order to grow, identify plant parts and their functions and discuss a video about plants. They conduct a controlled experiment with bean seeds and then record and observe the bean plants.

Students explore Newton's three laws of motion using a variety of activities. In this physics lesson, students calculate the average speed of a vehicle they constructed using distance and time information. They identify and draw the...

Second graders define condensation and evaporation. They identify and describe the steps in the water cycle. They ask questions to end the activity.

In this algebra lesson, students sample food and identify acceptance sampling. They create specific plans to meet specific situations as they sample the food. There are 6 questions.

Students identify the vertex and intercepts of a parabola. In this algebra lesson, students graph parabolas and factor quadratic equations. They perform transformation on the parabolas.

Learners describe the need of plants to have water, soil and sunlight to grow. They use the scientific method when completing experiments. They identify the core democratic values that are needed for a democracy to grow and compare them...
