Mystery Science - Invisible Forces - Forces, Motion and Magnets
Mystery #1 Push and Pull Forces: How could you win a tug-of-war against a bunch of adults? If you've missed the lesson, click on the image below, to the left (the link is good for 10 days after we have started the lesson)
In this Mystery, students will see that by learning to think about pushes and pulls — forces — they can accomplish extraordinary things! In the activity, Hopper Popper, students make a folded piece of cardboard jump high in the air, propelled by the pulling force of a rubber band. They discuss the forces involved in making this “Hopper Popper” jump.

Mystery #2 Balance of Forces - Engineering: What makes bridges so strong? If you've missed the lesson, click on the image below, to the left. (The link is good for 10 days after we've started the lesson)
In this Mystery, students will learn about real-life bridge design. In the activity, Paper Bridge Engineering, students will use their knowledge of forces to build a strong bridge that supports as many pennies as possible -- using only paper.

Mystery #3 Friction and Pattern of Motion: How high can you swing on a flying trapeze? If you've missed the lesson, click on the image below, to the left. (The link is good for 10 days after we've started the lesson)
In this lesson, students investigate the patterns of motion exhibited by a trapeze. In the activity, Trapeze Tester, students build a model trapeze. They make observations and take measurements of the motion of that model and use that data to predict the motion of a real trapeze.

Mystery Science - Animals Through Time - Animal Survival & Heredity
Mystery #1 Habitats, Fossils & Environments Over Time: Where can you find whales in the desert? If you've missed the lesson, click on the image below, to the left. (The link is good for 10 days after we've started the lesson)
In this mystery, students will explore the idea that the rock under our feet sometimes contains fossils. These fossils reveal how habitats have changed through time.

Mystery #2 Structures & Adaptations, Fossil Evidence, Classification: How do we know what dinosaurs looked like? If you've missed the lesson, click on the image below, to the left. (The link is good for 10 days after we've started the lesson)
In this mystery, students will learn how we can infer what the outside of an animal looked like, by using clues about their skeleton.
