Grade 3 Science

This series of special features may be used to provide enrichment to Dream Big and include behind-the-scenes videos and educational webisodes on engineering topics.

This film highlights the many ways in which engineers tackle problems big and small and explores how the principles of engineering can create a better future for all. Three female engineers are specifically profiled: one who specializes in creating structures that can better sustain earthquakes, ...

In this 30-minute broadcast, students will explore the computational thinking skill of testing and evaluating.

Testing involves trying something and observing what happens.Evaluation is about using critical thinking and judgment to determine if a set of criteria are met. If no...

In this 30-minute broadcast, students will explore the computational thinking skill of algorithmic thinking.

Algorithmic thinking is the skill involved in creating an algorithm. An algorithm is a series of ordered, logical and unambiguous rules or instructions necessary to solve a proble...

In this 30-minute broadcast, students will explore the computational thinking skill of pattern recognition.

Pattern Recognition occurs when you can identify patterns. When you identify patterns, you can create rules that allow actions to be repeated automatically. Pattern recognition c...

In this 30-minute broadcast, students will explore the computational thinking skill of abstraction. Abstraction reduces how hard a problem or task is by focusing on what's important. We do that by deciding what the important information is and then removing all the unnecessary details. Abstra...

In this 30-minute broadcast, students will explore the computational thinking skill of decomposition - the breaking down of a problem into smaller parts to make the problem easier to solve. Students will also begin to explore the computational concepts of sequences and loops.

In this 30-minute broadcast students will use STEM skills of observation, comparing & contrasting and sorting & classifying to further develop their computational thinking skills of pattern recognition, decomposition, abstraction and logic. During the broadcast, students will: - read a porti...

Professor Peter Plankton and Professor Tess Tube examine forces on structures. They specifically look at the impact of earthquakes and tornadoes. Footage from the recent earthquake and tsunami in Japan shows the devastating impact of these natural forces. Students will learn the difference betwee...

This short video is a question and answer quiz on the content found in the video, Structures: Man-made and Found in Nature. Part 2 (N1262).

Professor Peter Plankton and Professor Tess Tube explore structures. Students will learn that both humans and animals build specific structures with specific functions and that structures have many forms. Students are introduced to the complex honeycomb structure that bees build. Modern day struc...

Mother Earth has been neglected and is in desperate need of care and attention. In this DVD program, young people from around the world bring Earth's plight to the forefront. The Earth is emitting a silent scream and humans are not listening to the language of nature. The young people in the prog...

This short video is an interview with author, Helen Frost, who speaks about her book, "Monarch and Milkweed."

The short video is narrated by Helen Frost, the author of "Monarch and Milkweed." She gives more facts about monarch butterflies, describes their migration patterns using maps and presents viewers with a couple of web resources, useful for further learning about the butterflies.

This video introduces the life cycle of the monarch butterfly and its relationship with the host plant, the milkweed. As spring arrives, the milkweed sprouts through the earth and starts to grow. The monarch butterfly arrives and feeds from the milkweed. After mating, the monarch butterfly uses t...
