In this lesson, the teacher will use a small candle flame to demonstrate a chemical reaction between the candle wax and oxygen in the air. Students will see a molecular animation of the combustion of methane and oxygen as a model of a similar reaction. Students will use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

Students will be able to explain that for a chemical reaction to take place, the bonds between atoms in the reactants are broken, the atoms rearrange, and new bonds between the atoms are formed to make the products. Students will also be able to explain that in a chemical reaction, no atoms are created or destroyed.

A bioblitz is a short, intensive study of the biodiversity of an area. In this activity, students investigate and analyze local biodiversity using iNaturalist observations. They collaborate in small groups to explore observations and identification of various taxon groups. Then students create a class graph of data and draw inferences about biodiversity, invasive species, and endangered species in their local park. 

This is how you touch: Nerve cells throughout your body respond to external stimuli by sending nerve impulses to your brain. To put it another way, your skin’s nerve cells respond to the things you touch, allowing you to feel them.

This resource presents a short slide show about how humans interpret and respond to things they touch. After utilizing this resource, the students can complete the short test to assess their understanding.

In this first episode of Crash Course Physics, Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration.

Students make observations and analyze data to investigate how the duration of daylight changes throughout a year. They consider their own experiences in addition to evidence gathered from videos, data tables, and a line graph to describe the pattern in the changing duration of daylight from January to December.

The associated lesson plan Investigating Daylight Throughout a Year provides more support for teachers and students, including handouts and materials for diverse learners, as well as information for customizing the data to your location.

Cows have adapted to an incredible range of environments as they have provided people with milk, meat, leather, and draft power. As a response to the many uses and habitats of cattle, a wide variety of breeds have been developed. Breeders of beef and dairy cattle carefully select cows from known breeds that will yield the most meat and milk. In this video from Nature, learn about the most desirable traits in both beef and dairy cows.

In this game, students will learn how carbon atoms move through different carbon reservoirs during the carbon cycle. Students can play the game as a single-player or join others in a multiplayer format. Students will begin to understand the delicate balance of the carbon cycle while playing this game. 

We learn a lot about our surroundings thanks to sound. In this episode of Crash Course Physics, Dr. Shini goes over some of the basics (and some of the not so basics) of the Physics of Sound.

Jump in with both feet as you watch oobleck (cornstarch and water mixture) videos and learn about three states of matter: solids, liquids, and gases. Learn to use captions and charts to make reading comprehension less messy and loads of fun.

In these Hero Elementary activities, children explore solid and liquid materials. They observe, compare, and describe solid and liquid materials. They sort materials as solid or liquid. They find out how hot and cold can change the state of materials.

The way light behaves can seem very counterintuitive, and many physicists would agree with that, but once you figure out light waves it all starts to make more sense. In this episode of Crash Course Physics, Dr. Shini shows us how we know that light exists as a wave and why that's really cool.

Use text features like captions, bold print, glossary, and index to learn about the hot and cold states of water and all about penguins. Students will read an informational text on what makes water freeze, look at cool penguin pictures, learn weird penguin names, and read how penguins enjoy the water in all of its states.

We've all seen substances change as a result of changes in temperature. Water heated on the stove eventually changes from a liquid to a gas and seemingly disappears as it disperses into the air. But even at lesser extremes, temperature affects the density of water. In this video segment adapted from ZOOM, a cast member demonstrates how temperature affects the way water molecules react with one another.
