Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...

Avoiding lab safety rules will not give you super powers. The lesson opens with a demonstration of not following safety rules. Then, young chemists practice their lab safety while finding the mass of each item in a mixture and trying to...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Studens construct their own catapult. In this history of catapults activity, learners work in groups to make their own model of a catapult. Students use physics vocabulary terms explain how the catapult works. Learners test the...

Students play Chembalancer game and balance equations using the trial and error method.

Middle schoolers create a method for finding the area of a fame for a picture and then transfer their shared methods into algebraic expressions. They develop the algebraic language to communicate and solve problems effectively and...

Why doesn't the Supreme Court hear testimony from witnesses? How do they complete an entire proceeding in less than two hours? A helpful lesson guides scholars of criminology through these and other questions by explaining how appeals...

Litmus paper, why so blue? A chemistry lesson includes a pre-lab activity, practice calculating pH, an experiment measuring the pH in acids and bases, a titration demonstration, and a titration experiment. 

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...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

The focus of this writing worksheet is to have writers revise and edit a three-paragraph passage to eliminate wordiness and repetition. The paragraphs are quite long, and this should take most learners quite a while to complete.

Students understand the concept of a scientific model and how it relates to climate change.  In this obsesrvation and gathering data lesson students design a trial and error model using PowerPoint. 

Help young mathematicians build a solid understanding of division with this base ten block activity. With the help of these popular math manipulatives, children model different math problems in order to reinforce the...

Students conduct a mock trial and follow established procedures role-playing attorneys, witnesses, judges, bailiffs, etc. Students examine documents, present arguments and decide a case in which a sea lion is on trial for eating fish.

In this physics learning exercise, learners complete a lab activity and record their results in the charts shown. They calculate the speed for each trial using the total time and total distance. Students also graph their results.

In this secondary mathematics learning exercise, students solve a riddle/word problem involving the number of brother and sisters in a family.  The one page learning exercise contains one problem with the solution.

Students create models of structural isomers, geometric isomers, and polymers.  In this chemistry lesson, students are given definitions and molecular model kits to create a variety of different isomers and polymers.

Studying levers couldn't be more exciting! Learners build their own catapults and test the results as they make adjustments to the fulcrum. They compete against other groups to create the most accurate apparatus.

Can you build it? Yes you can! This interactive game includes four design challenges presented on separate cards. The cards outline the challenges with limited restrictions but with an end goal in mind. The competitions include building...

See how changes in initial populations and parameters affect a biological community. Individuals use a special software program to simulate a desert community with five species. They adjust initial populations to see how the community...

Ready, aim, fire! Launch to a new level of understanding as scholars build and test their own catapults. Learners explore lever design and how adjusting the fulcrum changes the outcome. 

Learners solve equations through trial and error. For this algebra lesson, students first estimate their answers and then calculate it to check their work. They solve problems involving roots and integers.

In this learned behavior worksheet, students review different types of learned behavior including habituation and trial-and-error learning. This worksheet has 7 short answer, 8 matching, and 10 fill in the blank questions.

Students create a spreadsheet using ICT. In this algebra lesson, students collect and graph their data using a spreadsheet. They find solution to a given problem using trial and error.
