Students relate thermal energy to heat capacity by comparing the heat capacities of different materials and graphing the change in temperature over time for a specific material. Students learn why heat capacity is an important property of thermal energy that engineers use in many applications.

The purpose of this task is to help students see the connection between aÖb and ab in a particular concrete example. The relationship between the division problem 3Ö8 and the fraction 3/8 is actually very subtle.

Most of the flavoring in gum is due to the sugar or other sweetener it contains. As gum is chewed, the sugar dissolves and is swallowed. After a piece of gum loses its flavor, it can be left to dry at room temperature and then the difference between its initial (unchewed) mass and its chewed mass can be used to calculate the percentage of sugar in the gum. This demonstration experiment is used to generate new questions about gums and their ingredients, and students can then design and execute new experiments based on their own questions.

Students keep track of their own water usage for one week, gaining an understanding of how much water is used for various everyday activities. They relate their own water usages to the average residents of imaginary Thirsty County, and calculate the necessary water capacity of a dam that would provide residential water to the community.

Pennies have a monetary face value of one cent, but they are made of material that has a market value that is usually different. It is the value of the materials that requires attention in this problem. While it is interesting to compare the face value with the value of the materials, this does not have any bearing on the calculations. Interference between these two notions of value is a possible area of difficulty for some students.

Today we’re going to explain how exchangers...exchange heat. We’ll look at concentric tubes, finned tubes, plate heat exchangers, and shell-and-tube heat exchangers. And we’ll look at some equations to help us sort through heat transfer and decide what heat exchangers are best suited for our designs.

Students follow weather forecasts to gauge their accuracy and produce a weather report for the class. They develop skills of observation, recording and reporting.

In this lesson, students will learn about types of land use by humans and evaluate the ways land is used in their local community. They will also consider the environmental effects of the different types of land use. Students will assume the role of community planning engineers and will create a future plan for their community. (Note: Teachers will need to check out the following book from the local or school library: Durell, Ann, Craighead George, Jean, and Paterson, Katherine. The Big Book For Our Planet, New York: Dutton Children's Books, 1993).

Build your vocabulary! This fun and quick quiz will enlighten students to words they need to learn more about! (Maybe head over to vocabulary.com to learn these words once you realize you don't know them!)

This resource was designed in collaboration with Nakota people from the Ocean Man, Pheasant Rump, and White Bear First Nations, and with storytelling by Shay McArthur, a Nakota speaker from White Bear First Nation. Designed for teachers of three-, four-, and five-year-old children, this activity opens with Nakota instructions for movement, gathering, and active listening.  An imbedded video of a Nakota story can be followed up with discussion questions (provided), and a related link.This is an ongoing project which received funding from the ESSP--Early Years Cultural Project.  More stories to come.

Kindergartners measure each other's height using large building blocks, then visit a 2nd and a 4th grade class to measure those students. They can also measure adults in the school community. Results are displayed in age-appropriate bar graphs (paper cut-outs of miniature building blocks glued on paper to form a bar graph) comparing the different age groups. The activities that comprise this lesson help students develop the concepts and vocabulary to describe, in a non-ambiguous way, how height changes as children get older. The introduction to graphing provides an important foundation for both creating and interpreting graphs in future years.

As written, this problem gives students all of the information they need to estimate the thickness of a soda can.

his is a version of ''How thick is a soda can I'' which allows students to work independently and think about how they can determine how thick a soda can is. The teacher should explain clearly that the goal of this task is to come up with an ''indirect'' means of assessing how thick the can is, that is directly measuring its thickness is not allowed.

This site offers lots of how to draw projects to try.

In this lesson from Art Hub for Kids, students are shown how to draw a Russian Nesting Doll.

In these YouTube lessons for young children, you start by writing a letter of the alphabet and turn the letter into an animal starting with the letter.

Check out the lessons to see the animals kids can draw from the entire alphabet!

So we know that sociology is the study of society, but what exactly *is* a society? Today we’re going to find out. We’ll look at Gerhard Lenski's classification of societies into five types, and the technological changes that turn one into another. We’ll also return to Marx, Weber, and Durkheim to consider how they understood societal change. Finally, we’ll explore Durkheim's concept of social solidarity.

Join Proton the cat as he tests out the professor's newest invention - goggles that allow a person to see sound in addition to hearing it. As you take a tour of the lab, you'll learn all about the science of sound, from how our ears allow us to hear sound, to the differences between louder and softer sounds.

Ever wonder why you can’t hear a dog’s whistle, yet when you use one, all the neighborhood dogs come running? Dogs are able to hear at higher ranges than that of humans.
Sound is a type of energy created by a rapid back-and-forth movement or vibration. When an object vibrates in the air, the air particles move around and cause other particles to move and bump into other particles, which carry the vibration through the air. This sound wave will keep going until it runs out of energy. When your ear is in range of the sound wave (before it loses all its energy) you hear a sound.
Sounds differ from one another because they vibrate at different speeds. This means, how often a sound wave will occur over time, or its frequency. When the vibrations are fast, you will hear a high note, and when the vibration frequency slows, the note will lower. Your ears collect and process the sounds, and then send signals to your brain in response

As the Atlantic Ocean warms, many marine species—including commercially important fish stocks—are moving further north along the Northeast United States. As a consequence, fishing boats based in traditional ports need to travel further to catch the same fish, or change their strategy to pursue different species of fish. In turn, businesses that serve fishing communities may need to purchase new equipment, develop new practices, or encourage workers to gain new skills. In order for fisheries and the businesses that depend on them to prepare for such changes, fisheries managers need tools to identify which fishery resources may be most vulnerable to our changing climate.
