Students study the role of controls. They discuss variables and list conditions, that if not kept the same for both flasks, could effect the outcome of the experiment. They come up with most of the following: Amount and temperature of...

Students gain an understanding of the real world applications of the scientific method. They design their own experiments to prove or disprove the existence of other modern legends, and they design and carry out an experiment to test a...

High schoolers 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...

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...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

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...

Watch the excitement grow as learners experiment with homemade rockets. Pupils create their own rockets from a soda bottle and experiment with launch angles. They discover the launch angle has a significant effect on the distance the...

How do different minerals affect the growth of plants? Budding botanists find out in a multi-week experiment that has them using solutions with specific mineral deficiencies. While there is a lot of preparation for the investigation,...

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

Pupils 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.

When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

Students conduct experiments in gravity by rolling objects down an incline and determining which ones roll slower than others. As part of the experiment, they design objects which will roll the slowest. Using digital movie cameras or...

There is a solvent called aqua regis that can dissolve gold! After observing a solubility demonstration, groups receive four known crystals and one unknown. Based on the demo, they design an experiment to determine the identity of the...

High schoolers explore algebraic expressions in this Algebra I lesson. They evaluate expressions using paper and pencil and then use the TI-83 to provide immediate reinforcements.

In this physics review learning exercise, students complete 24 matching and problem solving questions pertaining to math code, speed, experiments and variables, slope, and acceleration and average speed.

Students must design and conduct an experiment to determine which unknown liquid has a greater density based on basic information about the liquids and containers. Students are given specific materials to work with.

An outline walks your scientists through the steps of the scientific process. It begins by taking a general idea and developing a hypothesis based on related factors. Each investigator then plans a method for testing the hypothesis,...

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...

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...

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...

Use a hands-on approach to exploring the concepts of related rates in your AP Calculus class. Individuals explore the effect of the rate of change on a variable related to a variable they control. After analyzing the data they...

A link to a comprehensive macroinvertebrate guide gives you the information needed to prepare for this field study activity. Sample macroinvertebrates are collected from areas representing different environmental conditions. Junior...

Collaborative groups connect resistors and solar panels in series and measure electrical resistance, voltage, and current. The objective is to order 16 solar panels from strongest to weakest. They graph current-voltage and power curves...

In this science worksheet, students list the 6 steps involved in solving scientific problems. Students also answer questions about an example science experiment.
