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). If you want to catch up with us, ask Ms. Dekker for the supplies.
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). If you want to catch up with us, ask Ms. Dekker for the supplies.
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 Patterns of Motion, Gravity & Friction: 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). If you want to catch up with us, ask Ms. Dekker for the supplies.
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 #4 Magnets & Forces: What can magnets do? 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). If you want to catch up with us, ask Ms. Dekker for the supplies.
In this lesson, students will explore the surprising properties of magnets and experiment with an invisible force that acts at a distance. In the activity, Magnet Discovery, students use ring magnets and common objects to discover the push and pull of magnets and how magnets attract certain types of metals.

Mystery #5 Magnets & Engineering: How can you unlock a door using a magnet? 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). If you want to catch up with us, ask Ms. Dekker for the supplies.
In this lesson, students investigate magnetic attraction and repulsion. In the activity, Invent a Magnetic Lock, students apply their scientific ideas about magnets to create a useful product: a magnetic lock that can open a paper door. Students engage in the engineering design process to test and improve their designs.

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.
