Examine parts of an expression in this algebra lesson. Ninth graders identify the properties of the coefficient and their behavior to the graph. They graph the equation on a TI to see their results.

Steps of the scientific method are summarized, and then an example experiment is presented to allow practice identifying the steps. The graphics and animations are a little blurry, but this otherwise well-formulated presentation will...

Should athletes carb load before an event or consume carbohydrates during the competition? Scholars discuss how to set up a hypothesis and experiment to answer a question relating carbohydrates and athletic performance. Then, they read...

An inquiry-based algebra instructional activity explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as...

Young investigators conduct an experiment using the scientific method. They see how many drops of water fit on a coin; have them conduct several different trials. This involves making a hypothesis, looking at controls, and introducing...

Students identify with various programming texts; introduce material in different orders; and emphasize different concepts. Students read an introduction to LiveTexts; complete various activities; discover and apply its Global features...

Young scholars determine the velocity of a marble rolling down the incline. In this physics lesson, students identify the independent and dependent variables in the experiment. They construct and analyze a graph.

Students use a model experiment to complete an experiment on yeast. In groups, they identify the independent and dependent variables and use the scientific method to complete the activity. They record their observations and discuss them...

Students develop an independent procedure to investigate the germination of two types of seeds. Students must construct data tables or charts to record observations and results, graph the data, and analyze the data.

Did you know physicists can identify new particles by observing the path they take in a particle accelerator? Scholars explore the variables that determine the direction and radius of the circular path different particles take. They...

Students identify and test variables that may affect the accuracy of a rain gauge. They share findings of their research with the class in a 'mini-meteorology-convention'. They design an experiment with a control setup to test their...

Sixth graders set up a pendulum experiment deciding which variable to manipulate (length of string or weight on the string). They create a hypothesis, collect necessary equipment, and write out each step of their experiment. They then...

Ninth graders investigate the techniques of culturing bacteria. They culture bacteria using agar plates. Students identify and describe some environmental conditions that effect bacteria growth.

Students design an experiment to test the variables involved in the hatching of the Bruchid beetle.

Students collect and identify plant species from campus, create a home herbarium, and compare with the plant species from school.

Students collect and record data. They identify sex of butterflies. They make conclusions based on collected data.

Students explore the scientific method. In this scientific method lesson, students use information gathered from a "Seed Dispersal" lab done previously to complete a worksheet listing the steps of the scientific method.

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

Learners investigate the behavior of pendulums and identify the variables that affect it.  In this pendulum activity students complete a lab on pendulums, make conclusions about frequency and the period then conduct a controlled...

For this rate of solution worksheet, students determine how quickly a solute dissolves in a solvent by testing one independent variable such as temperature, particle size or the amount of stirring. Students design their experiments and...

Students investigate the pH of the soil in which different plants grow. They design and carry out an experiment to determine the factors that affect the growth of a population of plants, identifying and controlling major variables...

Students identify different types of functions and units of measurements. In this statistics lesson, students will collect data, graph their data and make predictions about their data. They plot a linear regression graph.

Pupils explore the concept of derivatives. They use implicit differentiation to determine points on a graph where a tangent line is horizontal, vertical, or oblique. Finally, learners find the derivative of a polynomial by...

In this nature of science worksheet, students identify four statements as "pure" or "applied" science and they read a short story about an experiment performed by a boy. They identify various components of the experiment...
