Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...

Pack just enough to fit. Crews determine what personal items to take with them on a trip to Mars. Each team must decide what to take with them on a two-and-a-half year trip to Mars and whether their items will fit within the allotted...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Would you believe that your digestive system stretches to five times your height?! Help your pupils to understand this relationship as they work through the laboratory exercise. The first instructional activity of a 12-part series is a...

Get a hands-on look at a local habitat. A three-part activity begins with a discussion of the characteristics of a local habitat. Pupils then test their knowledge by playing a game to match animals to their habitats. Finally, they go on...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

In this energy transformations worksheet, students fill in the objects to a chart for which one would fit each energy transformation, and fill in the blanks to a chart about which energy transfer fits each object. Students complete 6...

Plastic math? Have young learners count and name the number of plastic items in their centers. Kindergartners match sight word cards to the number of plastics in a given group, while learning that plastics come in all different shapes,...

Young scientists explore many different types of energy including light, heat, nuclear, sound, potential, and more. They match the types of energy and identify when energy transfers from one type to another.

There's no need to stay inside; get out of the classroom and create a scaled map of the solar system on your playground field! In collaborative groups, scholars identify the distance between the sun and other planets, place planet...

Students investigate shadows.  In this shadows and technology instructional activity, students listen to the book Ten Grouchy Groundhogs or Gretchen Groundhog, It's Your Day! and discuss how shadows are made.  Students match...

Assist your secondary special education class for understanding risky behavior, hygiene, and STDs. The class discusses how germs spread, how people get sick, and what needs to be done to prevent the spread of communicable diseases. They...

Students define the sense of smell. In this smell sense instructional activity, students review their five senses and define the importance of smell. Students practice smelling and identifying items in bags. Students discuss the...

Students explore the concept of density. In this density activity, students determine the density of various objects. Students use the density of the various objects to predict the density of various unknown solutions.

In this celestial objects quiz worksheet, students complete an on-line quiz, clicking on questions and matching answers, scoring 1 point for each correct answer. A printed version is available.

Students listen to a read aloud about African animals as they access a watering hole. They discuss the characteristics of Africa such as the temperature, it distance from the students, and lifestyle of the animals. They talk about how...

Students explore the sense of touch. They investigate unknown solids using the sense of touch. Pupils use their senses of touch to match feely gloves. Students explore body parts, by tracing their hands and feet on paper. They create a...

Young scientists get to the heart of the matter as they complete this worksheet on the properties of solids, liquids, and gases.

How important is momentum? Pupils investigate and apply the definition of momentum as they conduct analyses during a series of one-dimensional collisions. They infer the relative masses of two objects by carefully staging and predicting...

Dramatize the stars and planets as they become a visual representation of the solar system in this activity. Young astronomers track and simulate various constellations as they orbit the Earth to learn the position and motion of...

Militaries throughout history have used topography information to plan strategies, yet many pupils today don't understand it. Scholars use Legos and a contour gauge to understand how to construct and visualize topographic profiles. This...

Earth is 149,600,000 km, or 92,957,130.4 miles, from the sun. Young astronauts create an interactive model to learn the distances between planets. Nine groups, each representing a different planet, are spread around at class-calculated...
