Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Learners design an experiment to test for the concentration of chloride in products. In this analysis of chloride concentration lesson plan, students develop and conduct an experiment to find the amount of chloride ion in a substance of...

Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an...

What a wonderful way to explore wind power! Through this instructional activity, learners get a background in the history of wind power, create their own wind turbine, and the test their designs. This is a terrific way to tie scientific...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Examine parts of an expression in this algebra lesson plan. 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.

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

Students experiment, observe, measure, and analyze what occurs during an exothermic reaction. They safely design an experiment, control variables, and properly dispose of materials.

Students designs and conduct a scientific experiment that identifies the problem, distinguishes manipulated, responding and controlled variables, collects, analyzes and communicates data, and makes valid inferences and conclusions.

Young scholars 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...

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...

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

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 study motion and how different variables can change the outcome.  In this motion lesson students answer questions about their experiment and see what the different variables did. 

Designed by School Power...NaturallySM, this lesson familiarizes advanced earth science and physics learners about the variables that affect our supply of solar energy. They examine gas spectra and perform calculations. There is an...

Change one variable and try again. Teams build basic balsa gliders and collect data on their flight distances and times. Through collaboration, the team decides on two modifications to make to the basic design and collect data for the...

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...

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...

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

How does the dirt get out of your drinking water? A hands-on activity introduces the use of flocculants to help clear solid particles out of water. The plan walks learners through the process of setting up an experiment that...

Explore the concept of systems of equations in two variables and use matrices to solve them. Young mathematicians enter coefficients and constants into a matrix and then solve using row reduction. Instructions on how to use the shortcut...

Students investigate transition metals and their oxidation states. In this complex ion and oxidation states lesson plan, students use 6 transition metals and mix them with ligand solutions and oxidizing agents separately. They test their...

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

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...
