What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

A chemistry lesson presents 14 chemical reactions for scholars to observe, write the equation, and balance the equations. Additionally, it provides ways to extend the activity as it relates to catalysts.

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

Students summarize the steps of the scientific method. In this life science lesson plan, students explain the importance of varying only one variable at a time. They analyze possible flaws in their experiment.

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 equilibrium worksheet, students solve 4 problems. They calculate reaction quotients for problems, they examine a reaction in equilibrium and predict solutions to changes made to the reaction.

Students predict which of two glasses is 1/2 full using visual estimation, height measurement, and liquid measurement methods. Mathematical equations to accurately solve the problem are determined and verified.

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 brainstorm on ways they use water, and where water comes from. They view video, Down the Drain, to gain specific facts about water use, properties of water, problems of water and the water cycle. They perform a lab activity...

What does the atmosphere on Mars look like? This fourth lesson in the series of five is designed for high schoolers. Scholars apply previous knowledge to add atmosphere to Mars in an online simulation. This comprehensive lesson includes...

Mars used to have liquid water, can you make it come back? Use the instructional activity and simulation to understand why Mars lost its magnetic field, why atmosphere is important, and what gravity has to do with it. This is...

What a wonderful way to explore wind power! Through this lesson, 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 principles to...

A messy fountain is potentially an energy experiment in disguise. Groups investigate the variables in creating a fountain from soda and Mentos. The last activity in a six-part series on energy has the class observe the fountain in terms...

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...

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...

An interactive lesson helps individuals learn to graph inequalities in two variables. Scholars can adjust the interactive to present the inequalities in standard or slope-intercept form.

Perform the operation ... and then do it again. Scholars investigate recursive formulas by creating and graphing them. Using the interactive, pupils set the variable, determine the initial value, and type in a recursive formula.The...

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...

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...

In this experimentation worksheet, students review the steps of setting up an experiment, determining the correct procedure and analyzing the data. This worksheet has 23 fill in the blank questions.

Students explore the concept of hardness. For this physical science lesson plan, students will be using clay heated at different temperatures to study hardness based on the indention left. Students will also be identifying the variables...

Students explore the use of variables in the scientific method. They identify the dependent and independent variables through pH testing. Students construct graphs of their data and analyze their findings.

Students evaluate the notion of aging by reviewing some of the studies that occurred on John Glenn's space shuttle mission.

Students 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.
