Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...

Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Learners measure water and make predictions about efficiency.

Third graders conduct an experiment. In this floating and sinking liquids lesson, 3rd graders discuss density and investigate it using syrup, vegetable oil and colored water. Students observe the results and complete a worksheet.

Which is the larger amount? Two-fourths of 10 dollars, or one-fourth of 100 dollars? This type of question is the main focus of a worksheet that has learners comparing fractions by their relative size. Each problem contains...

Students are challenged to come up with a good estimate of the amount of air in foamed polystyrene products. They use this gas evolution experiment and as such have students measure the gas generated when foamed polystyrene is degassed...

Students review the procedure for determining appropriate types of measurements for given situations and measurement conversions. They figure perimeter, area, and volume of 2 and 3 dimensional objects.

Students explore sinking and floating.  In this buoyancy lesson, students conduct an investigation dealing with regular and diet soda. Students drop various soda cans into water and then discuss why some float and some sink. 

Learners are explained that they are going to use a part of Thomas Paine's 1776 pamplet Common Sense as a starting point for exploring about argumentation, or persuasive writing. They are given a copy of the excerpt. Students discuss...

Educate your class about blood alcohol levels by combining health with math practice. Class members read a little bit about blood alcohol concentration and then solve some problems related to determining alcohol levels and alcohol...

Learners compare the pressure of water at different depths and gain an understanding of how increased water might affect animals living in deeper waters. They participate in an experiment to show that depth, not volume, affects water...

Students hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.

Pupils confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.

You don't want to flush your money down the drain! Have your classes complete a financial comparison between two different types of toilets. They use linear modeling to determine the most cost-effective model.

Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.

Young scholars explore the changing density of water. For this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to...

Students investigate the properties of solids, liquids and gases. In this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...

In this buoyancy worksheet, students read about why objects float or sink. Students apply the Archimedes' Principle in a buoyancy lab. Students complete 1 graphic organizer.

Get your class outside to observe their surroundings with a lesson highlighting weather patterns and seasonal changes. First, learners take a weather walk to survey how the weather affects animals, people, plants, and trees during...

Back to the basics (of surface tension). The first installment of a nine-part series teaches young scholars about the basics of surface tension and how it relates to water droplets. They also learn how this concept allows for the...

Students determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...

Students ask yes-no questions to identify a secret book. In this asking questions lesson, students ask yes or no questions about books to identify a secret book. Students identify the book and then read one of the example books.

Students define density and observe that things that are less dense than water will float. Students find the density of copper, iron and aluminum
