Third graders discuss how Aristotle concluded that the Earth was round. As a class, they review theories about the Earth's shape and describe how life on Earth would be different if it were flat. Individually, they make a moon book in...

In this scientific statements worksheet, students are given 35 statements and they are to identify if each statement is a fact, law, hypothesis, theory or belief.

Logical thinking is at the forefront of this jam-packed lesson, with young mathematicians not only investigating geometric concepts but also how they "know what they know". Through each activity and worksheet, learners wrestle with...

Fourth graders measure the change in the size of their shadow over time. They visit a fixed structure and record the date, the time, and the measurement of the length of their shadow. They do this over the course of the school year. They...

Students determine how to find North using a watch and their shadow. In this finding North lesson, students go outside on a sunny day and work with their shadow and a wrist watch to find out which direction that North is. They examine...

Does the space shuttle have an odometer? Maybe, but all that is needed to determine the distance to the moon is a little geometry! The lesson asks scholars to sketch the relationship of the Earth and moon using shadows of an eclipse....

In this solar storms worksheet, students use a diagram given the location of two STEREO spacecraft satellites, a coronal mass ejection, the sun and the Earth to solve 2 problems about the coronal mass ejection. Students use segments,...

Students investigate how all links in the food chain are related. In this animal habitat lesson, students hypothesize about what would happen in the food chain if an endangered species were to become extinct. This lesson also includes an...

In this solar surface worksheet, students use a photograph taken by the Swedish Vacuum Telescope to answer 6 questions about the solar features in the photograph. Students determine the scale of the image, they determine the smallest...

In this math worksheet, students read informational paragraphs and then answer 18 questions using data from their readings. Questions are about vectors, positions, distance and orbits.

The ancient Mayans had a complex calendar and number system with a rich history. In fact, the date 12/21/2012 was the center of much controversy as to whether or not it was the end of time. It wasn't the end of time, but...

Students examine total eclipses of the Sun and their limited regions of totality. They explain that this limited view occurs because the Moon is close enough to us for different points on Earth to view it differently.

In this plasmasphere activity, students read about the dilute region of gases 10,000 kilometers above the Earth where atoms are ionized. Students use a photograph taken by the IMAGE EUV instrument to answer 3 questions about the...

In this finding mass in the cosmos instructional activity, students use the equations for the force of gravity, the centrifugal force pushing a planet outwards and the speed of a planet to solve 2 problems. They find the mass of primary...

In this algebra worksheet, students calculate the different time of the day that different countries see the sun. They convert between different time zones. There are 3 questions with an answer key.

Learners describe how the sun heats the Earth, explain the nature of infrared light, explain how thunderstorms are formed and use infrared maps to predict severe weather.

Sixth graders recognize that the Earth was different in different eras. In this Mesozoic Era lesson, 6th graders compare the time frame of the different eras and how long they lasted for by graphing them. Students study the...

In this math worksheet, students explain the vector parametric equation for a line, scalar parametric equations, symmetric equations, and the implicit equation for a line.

Pupils are able to read and also use a variety of timetables and charts. They perform calculations with time, including 24-hour clock times and time zones. These are very important concepts that Students probably have to bear in mind...

Students construct a simple spectroscope. They observe the emission spectrum produce by a source of light.
