Students create a paper model to illustrate sea-floor spreading.

Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

Take foldables to all new heights. Pupils build and fly different types of paper airplanes in the 14th portion of a 22-part unit on aviation. Groups collect data on distance and flight time for each plane and compare the data from the...

A model car, a life size car, now compare their sizes. Hmmm. Ok, set up a proportion and then figure out a ratio, and now you can express the relationship in terms of scale. Watch this video and the teacher will demonstrate just how to...

Build on the concepts of shared and repeated subtraction division. The teacher guides the class through using both methods for solving a word problem, including formulating an equation. After pairing off for independent practice, one...

Seventh grade math is so much fun! They solve 10 different problems that include using patterns to complete a table, describe the pattern, and identify the specific term in the pattern for each. Then they give a description of the...

Students explore the concept of fairness. For this fairness lesson, students play four probability games. Students determine who has the best chance of winning each of the four games. Students discuss which games gave an unfair advantage.

Like the cubs in A Fair Bear to Share, your 2nd grade class will practice adding and subtracting double-digit numbers by grouping, regrouping, and sorting a collection of objects. This requires many resources, but it is well worth the...

Students engage in a lesson that is concerned with the concept of designing a dream playground. They conduct a survey of specific traits needed for the equipment. Students draw a picture of the ideal playground and then construct a model.

Fourth and fifth graders look at the pictures of nine circle fraction pieces and draw lines between the ones that show the same amount. They label each fraction circle. They split fraction pieces in the next 9 examples, and draw the new...

In this understanding the y-intercept worksheet, students solve 4 problems related to the y-intercept of a graph. First, they explain the relationship between the height of a float in a gas tank and the number of gallons in the tank....

In this formulating and solving systems of equations worksheet, students solve 4 different problems applying methods of solving equations differently. First, they describe the situation in steps 1 and 2, specifying the variables that...

This unit enables scholars to apply the rule for area of a triangle (area equals half base times height). They practice multiplication and division strategies as they calculate areas.

Students engage in a lesson that is concerned with the location of structures inside the earth. They conduct research using a variety of resources and use the information to create a model of the Earth that focuses upon the location of...

Keep everything under control. The lesson, the 16th segment in a 22-part unit, provides a more detailed look at the parts of a plane, specifically the control surfaces. Pupils learn about the construction of the wings and the tails and...

Let's go fly a kite ... oops, a paper airplane! The 13th segment in an aviation unit of 22 relates the parts of an airplane to paper airplanes. Pupils learn the functions of the control surfaces of a plane to really make their knowledge...

In this fractions worksheet, students look at a graph showing a particular amount shaded; from this, they select the best choice representing the portion shaded. There are three different graphs to identify.

In this number and operations worksheet, students solve and complete 3 different sections of one problem that uses the Pythagorean theorem to solve. They use the model illustrated to determine the meaning of the Pythagorean theorem....

Learners 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. 

Students study the concept of a scientific model and demonstrate climate change models.  In this scientific activity students design a model using direct and indirect evidence and use it to make hypotheses.

Students simulate a working cell by making a model. In this cell organelles lesson, students research the cell and create a model of a cell cross section.  Students make observations as they navigate an online site showing the inside of...

Students are able to construct a candy model of DNA. They are able to list all of the parts of DNA that they investigated earlier. Students are able to describe what each part of DNA does. They create an edible model of DNA strands.

Fifth graders, in groups, create paper bag "globes", complete with magnetic poles. They use compasses to determine and label various locations (N. and S. Poles, Prime Meridian, Equator, etc.) and finish it by drawing in the continents...

Students build a model to simulate parts of the water cycle. They recognize and explain the essential elements of the water cycle.
