Bend a Carrot
Conditions of Use:
Read the Fine Print
Rating

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control. After about 15-30 minutes, the carrots with salt become flexible and water can be seen in the bag. Extensions include measuring the amount of water lost from the carrots, varying the salt solutions, and investigating other liquids, vegetables or solids. Part of the "No Hassle Messy Science with a Wow" activity guide by OMSI, where all activities use only household materials.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter. This resource includes definitions of key words (habitat, carnivores, herbivores, omnivores, extinct) as well as discussion questions to further learning.

Jelly Beads

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads. After rinsing off the beads, learners are invited to touch the beads and investigate their texture. Learners discover that alginate (made from seaweed) is often added to food products (ice cream, chicken nuggets) to improve texture. Learners can experiment with different variables: leaving drops in the calcium chloride for different amounts of time, adding different amounts of alginate solution, pouring calcium chloride over a shape of alginate solution in a petri dish. This activity is currently used in the Biochemistry Unit in OMSI's Chemistry Lab. Cost estimates are per 100 learners.

This activity is on page 3 (continued on page 2) of the pdf, part of the Simple Machines Discovery Box. In this fun activity, learners "create" a complex machine by simulating the parts in action. Learners move their bodies and make sounds as if they are individual parts of a moving machine. Then learners discover what happens when part of a machine is broken and problem solve ways to fix it.

Older or Younger?
Conditions of Use:

This quiz shows you several pairs of animals, and asks you to guess which one is older. You look at dogs, rats, gorillas, horses, roundworms and an X-ray of a dog's hips. After you click on the one you think is older, the correct answer is revealed, along with an explanation of what happens when these different animals age and how to tell an older individual from a younger one.

In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure. There are clear, colorful photographic step-by-step instructions on how to fold the small shapes and how to assemble them into larger figures. There are also URLs for several origami websites and several recommended origami books.

Sink or Swim?

Learners observe a tank of water containing cans of diet and regular sodas. The diet sodas float and the regular sodas sink. All the cans contain the same amount of liquid and the same amount of air. However, the sugar in regular sodas makes them denser than water so they sink. This is written as an exhibit, but can easily be adapted to become a demonstration or hands-on activity.
