In this calculations activity, learners find significant figures in numbers, they determine densities of substances and objects, they convert from one metric unit to another and they determine the appropriate unit of measurement for...

In this calculations review worksheet, students convert from one metric unit to another, they identify significant figures in numbers, they find density of substances, and they solve problems using dimensional analysis.

Create tomatoes in 15-20 minutes using this fun and interactive lesson plan! Learners listen to a book about tomatoes (recommendations listed), and focus on the vocabulary word tomato. They count the syllables...

In this stellar magnitude scale worksheet, students use a scale showing the magnitude of objects in the sky to answer 5 questions about the brightness of the moon, the planets and stars.

In this Milky Way galaxy worksheet, students are given a table of distances and angles of nebulae and star clusters from the sun. Students plot each one on a piece of paper and solve 2 problems using the data.

Students explore the reaction rates of an enzyme-mediated reaction through experimentation. In small groups, they use everyday objects to demonstrate the effects of environmental variables on enzyme function. Students graph and...

In this experimental design and measurement worksheet, learners answer questions about independent and dependent variables, they write hypotheses, they identify instruments that measure mass, weight, and volume and they calculate the...

Students investigate archeology. In this archeology lesson, students research the process of excavation. Students participate in a mock-excavation and sort objects by physical properties.

Students design a conceptual experiment to test whether mimics actually benefit from the fact they resemble other organisms or objects. They define the term mimicry. They focus on insects that resemble bees and wasps.

Learners experiment to show the components that dictate centripetal force in an object. They observe how the object moves in a circular path around a central point.

First graders investigate objects using rulers and magnifying glasses. They record their observations using a data-recording sheet and write a characteristic for each item they observe. They use the ruler to solve math problems.

Students examine how to plan for prudent use of trees so that we never run out of this natural resource. They determine what the oldest wooden object in their home is and draw picture of it. They observe a cross section of a tree and...

Explore how sound travels as waves with a straightforward lesson that explains the basics of waves in relation to sound. The presentation considers sound waves in both open and closed pipes and shows how to calculate wavelength and...

In this Sun and Moon worksheet, students solve 6 problems about the angular scale of the images given, the size of the features on the images and the area of the features shown.

In this asteroids of the solar system worksheet, learners observe a diagram showing all the minor planets found in the orbit of Mars. Students answer 4 questions about the minor planets inside the orbit of other planets, they find the...

Learners construct models of microorganisms recognizing size relationships-comparing the size of viruses with the sizes of bacterial and eukaryotic cells. They put into perspective just how small microbes are by comparing the size of...

In this exploring cities from space instructional activity, students use a satellite image from the QuickBird Satellite to determine the image scale. They use the image scale to calculate the length of the Bellagio Hotel in Las Vegas,...

In this power-law functions worksheet, students solve 3 problems using data from the Wide-field Infrared Survey Experiment in the constellation Carina. Students use a photograph to determine the number of stars as bright as the brightest...

Students demonstrate the process of science by posing questions and investigating phenomena through language, methods and instruments of science as they experiment at four teacher-created stations to explain the fundamentals of magnetism.

Middle schoolers observe and investigate the human skeletal and muscle systems. They become aware of the versatility of movement as well as gain experience through the use of diagrams and hands on activities. An extensive vocabulary is...

Students explain how the food chain works. They contrast predators with prey and describe their function in nature. Students discuss how the food chain aids in keeping nature balanced. In small groups, they play a game that simulates the...

Students are introduced to the characteristics of trees and different techniques to identify them. They distinguish between a deciduous and a coniferous tree. Students describe at least four characteristics used to identify trees. They...

Second graders investigate the body of a cricket. In this biology activity students use tools to gain information about the insect the cricket. Students observe and identify features and describe how these features help the cricket live...

Students experience a positive science experiment and study fundamental concepts of measurement.
