Plants take cues from the environment—change in daylight hours and temperature—to complete their seasonal life cycles. Lesson four in the series of six has classes collect phenology data on plants. After taking initial observations,...

Scientists monitor seasonal changes in plants to better understand their responses to climate change, in turn allowing them to make predictions regarding the future. The last activity in the series of six has scholars analyze BudBurst...

How does fire keep itself going? Explore the ways that heat uses fuel and energy with a lesson about the fire triangle and combustion. Several activities demonstrate how heat moves from warmer objects to cooler objects, as well as the...

Get to the know the common house mouse and the Norway rat with an activity that reinforces reading comprehension skills. Scholars read a three-page document detailing key information about mammals, specifically rodents, and use their...

Continuing their study of beneficial insects, young entomologists discover where in the world some of these bugs are. By labeling, coloring, and using the scale on a map, pupils explore the territories and arrival of the Asian lady...

Purifying air and water, providing soil in which to grow crops, and moving water through its natural cycle are all services an ecosystem provides that benefit humans. Lesson four in a series lets learners explore and discuss the value of...

Photosynthesis requires energy and produces food, and cellular respiration produces energy and requires food. An interesting lesson analyzes the factors that affect the rates of photosynthesis and respiration. Classes spend one day...

Act out the circulation of blood in the body with an innovative activity. Kids act as either body parts or blood, and carry necessary nutrients and waste throughout different stations to represent the way that oxygen circulates. 

Forests, through sequestration, capture excess carbon dioxide in our atmosphere and store it, aiding in climate change. The third installment in a four-part series on how climate impacts forests explores carbon sequestration....

Oceans absorb half of the carbon dioxide and 80 percent of the greenhouse gases released into the atmosphere. Scholars learn how and why the oceans store heat more effectively than land and how they help mitigate global warming. Pupils...

Caterpillars' and moths' most obvious change is physical, but what happens to their nervous systems as they complete metamorphosis? Through a hands-on investigation, young scholars construct the nervous system of a caterpillar. They then...

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Can you create a rock band? Scholars learn about the creation and transmission of sound in a hands-on STEM activity. First, they explore the transmission of sound using a tuning fork. Then, they must solve the problem of missing...

How much trash does an average family produce in 24 hours? Where does that trash end up? Get your youngsters thinking about ecology and conservation as they discuss the impact pollution has on the marine environment. After a deep...

Explore the chemical components of water through an electrolysis reaction. Scholars use a battery to divide various water solutions into different gases. As they collect the gases, they measure the volume and make a comparison to the...

Why do we sweat? Scholars analyze data about body temperature, sweating, and other factors to better understand sweating. They note the changes after drinking ice water to sweating, skin temperature, and body temperature. Analysis...

Compare and contrast the characteristics of fresh and salt water marshes. After exploring the typical plants and animals found in each marsh type, participants use a set of flash cards to sort into fresh and salt water marsh life. Their...

Young scientists study the construction of a battery through experimentation. They engage in five experiments which combine to create a thorough study of the history of batteries beginning with a model of the first battery.

How do we count the fish in the ocean? An engaging lesson models how to estimate fish populations with observational surveys. Class members begin by studying the behavior of fish on the coral reef in the oceans. They...

People associate calories with food, but what is a calorie? Young scientists measure the number of calories in samples of food to better understand the concept. They test a variety of samples, take measurements, and compare their results...

Young scientists explore hearing through multiple experiments, demonstrations, and activities. They focus on the changes in hearing over a lifetime, how we can determine where a sound is coming from, and the ability to filter noises.
