In this sides and vertices worksheet, students decide between 2 shapes to show which has more or less sides or vertices. Students complete 6 problems.

Using a dry cleaner bag and a blow dryer, create a hot air balloon! The materials list suggests obtaining one dry cleaner bag per student, but since this is probably inconvenient, consider doing this as a demonstration during a...

Individuals explore solubility by modeling how water dissolves salts. They then view a video and compare how well water and alcohol dissolve salts, relating their comparisons to the structure of each molecule. 

In the sixth lesson in a series of 21, scholars use NASA data to graph and interpret albedo seasonally and over the course of multiple years. This allows learners to compare albedo trends to changes in sea ice with connections to the...

Through a variety of physical and theoretical situations, learners are led through the development of some of the deepest concepts in high school mathematics. Complex numbers, the fundamental theorem of algebra and rational exponents...

Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

According to the resource graph, which costs more: peaches or plums? Algebra learners compare two proportional relationships and then throw in a banana. Leaving out the scale helps students become intuitive about graphing. 

Students explore the realms of measurement. In this math lesson plan, students analyze and solve problems in which rectangles with identical perimeters are compared to maximize or minimize area. This lesson can be extended for algebra,...

Hang out at the beach and listen to some relaxing tunes, all while developing basic math skills. An endless source of fun and learning for young children!

Young scholars compare and contrast the Boston Massacre to the Kent State shootings. In this compare and contrast lesson plan, students review what happened in each case and compare them using a Venn Diagram.

In this mathematics worksheet, 1st graders identify which items pictured weighs more or less than a pound. Then they circle the objects that weigh more and place an X on the object that weigh less than a pound.

Get some competition going in your life science class. Give lab groups a variety of plant parts, all of them fruits, except one. Their mission is to make observations, compare and contrast, in order to be the first to identify the...

Students discuss elements of word problems: key words, data, computation clues, and unnecessary information and use the four steps of problem solving to find a solution and check for reasonableness.

Bring writing to life with this lesson in which elementary and middle schoolers create a display of the imagery they identify in a series of Gary Paulsen books. They read the suggested materials, identify imagery and descriptive...

Keep within a water budget. Learners find out that less than 2.5% of Earth's water is available to drink—and that there is a fixed amount of water. Scholars read an interesting article comparing the available water to a game of Monopoly...

Slopes are not just for skiing. Instructors introduce class members to the concept of slope and teach them how to calculate the slope from a graph or from points. The lesson also includes the discussion of slopes of parallel and...

Getting a ship into orbit isn't rocket science. Oh, wait...that's exactly what it is! Learn the basics of the concepts of thrust, launch angle, and gravitational pull in this fun and progressively challenging game.

Students work together to compare and contrast Mars and Earth. Using the internet, they answer questions given to them by their teacher and calculate answers showing their work. They graph their answers and discuss the results of the...

Here is a physical science activity where pupils place thermometers inside of a white and a black paper pocket and place them under a lamp. They record and compare the temperature increase over a ten-minute period. Have your class...

Young mathematicians collect data and graph it. They work collaboratively to collect data regarding the span of arm length versus height and graph the data they collect.

Studnets participate in a trading simulation game in which they experience the effects of trade and how trade can increase wealth.

Do your historians fully grasp the consequences of being at war? Help them connect past with present through this group research activity, which has students analysing repercussions suffered by citizens of countries in conflict. Students...

Students view a nicely-put-together slide show on comparative and superlative forms of adjectives and adverbs. After going over examples of each, students take a 2-part quiz which tests their knowledge of how to properly use these forms....
