two female presenters showing Lego

Presented by Nolan Miyahara

Description: Learn how to create a balloon powered LEGO race car.

Materials: Basic LEGO including wheels, jumbo straws (boba straws), black (electrical) tape or equivalent, scissors to cut the tape, party size rubber balloon, air hand pump (sports ball pump).

male presenter mixing liquid for slime

Presented by Luca Preziati

Description: See hydrogen bonding in action. Use this simple recipe to make slime at home using glue and borax. You can even add flowers to give your slime a Hawaiian twist.

Materials: Elmer’s glue (white or clear), borax, water, food coloring, large bowl, spoon, flowers (optional)

Age range: For ages 5+

Disclaimer: While it is safe to play with slime, ingestion of large quantities can be dangerous. Slime is not safe for unsupervised toddlers. Slime is safe on most surfaces and can even be used to clean plastic, glass, and leather because of its adhesive properties. Slime strongly binds with fabric and should be kept away from it. However, if that happens, you can remove slime from fabric with water.

Age range: Children of any age can take part in this activity, with the help and supervision of an adult.

male presenter holding pieces of lung model

Presented by Sandro Jube

Description: In this video, you will learn how to construct a homemade lung model. Our lungs sit on top of a muscle called a diaphragm. When our diaphragm contracts, our thoracic cavity expands creating negative pressure (a vacuum) inside of our lungs, forcing the air in (inhalation). When our diaphragm relaxes, it decreases the volume of the thoracic cavity, creating positive pressure inside of our lungs, and the air will be sucked out (exhalation). The balloons inside of the cup represent our lungs, while the piece of balloon at the entrance of the cup represents the diaphragm. When the "diaphragm" is pulled down, negative pressure is generated inside of the cup and the "lungs" (balloons) will inflate, and when the "diaphragm" is pushed in, positive pressure is generated inside of the cup, and the "lungs" will deflate.

Materials: 20 oz clear plastic cup with 1/2" whole through the bottom; 2 x 9" balloons; 1 x 12" ballon with the neck of the balloon cut off; 1 x 1/2" pipe PVC tee; clay or playdough; tape; scissors

Age range: All ages

someone drawing a neuron character with colorful pencils nearby

Presented by Sheri Hiroi DuBay

The hope is to get people excited about the brain and science so they will want to learn more! It uses minimal materials. Best part: It’s easy and fun!

Materials: Paper, pencil, coloring pens

Age range: For ages 5+

closeup of hands holding yogurt jar and spoon

Presented by Helmut Kae

Description: Fermentation is a process in which bacteria and/or fungi turn raw foods into foods that will last longer, are healthier, and taste better! Common examples of fermented foods include kimchi, kombucha, and yogurt.

Yogurt has been around for at least 7000 years, and has been extremely important in feeding many early civilizations. Yogurt is made when a group of bacteria called the Lactic Acid Bacteria eat the sugars in milk, and make lactic acid. The lactic acid curdles the milk proteins, turning the milk into a sour gel-like deliciousness we call yogurt. The process of yogurt making can be complex, but it can also be very simple. The key is to add enough Lactic Acid Bacteria to the milk so that the other “bad” bacteria don’t spoil the milk. And the best source of the “good” bacteria is yogurt.

To make yogurt, all you need to do is to add about a tablespoon of yogurt (I like to use the last little bit of my snack) to about a glass or bowl of milk. Give it a nice mix with your spoon, and then cover with a cloth or a paper towel. Set it aside and wait. Check it every day. If it starts to look and smell funny, that means the “bad bacteria” have won - it’s time to throw this out and start again. If it looks and smells like yogurt, you just made yogurt! You can add some honey or fruits to your freshly made yogurt to jazz it up a little. Enjoy!

Materials: Milk, yogurt, cloth or paper towel, rubber band

Age range: All ages

closeup of hands holding kiwi in a bag and test tube

Presented by Alyssa MacDonald

Description: Kiwi DNA uses household items to extract the DNA out of Kiwi (or other fruit).

Why it works: From Biology for a changing world: DNA (deoxyribonucleic acid) is the hereditary molecule that is common to all life forms – from plants to bacteria to fungi – and that is passed from parents to offspring. DNA serves as the instruction manual from which we are built; it’s the reason why you look like your parents, an aunt, or perhaps even a grandparent. Where can you find DNA? The molecule exists inside the nucleus of almost every cell in our body in the form of chromosomes, strands of DNA wound around proteins. In order to isolate DNA from the kiwi (plant) cell, we will need to “break through” the cell wall using the “mushing” technique in which the students squish the kiwi fruit and extraction solution in a ziplock bag. The extraction solution made of soap and salt. The soap destroys the cell and nuclear membranes, allowing the DNA to get out. The salt causes the proteins and carbohydrates to precipitate, while the DNA remains in solution. The baggie is then placed in the ice bath to stop the DNases (enzymes that destroy DNA) in the cytoplasm from breaking apart the DNA. The solution is then filtered through a coffee filter to remove the pieces of the cell we are not interested in, including proteins and carbohydrates. The filtered liquid is then placed in a vial and 2 ml of cold ethanol is added to precipitate the DNA. Each person’s DNA is unique. DNA is made up of two strands of molecules, called nucleotides, linked together in long chains. Each nucleotide has three parts: a deoxyribose sugar, a phosphate group, and a base. The phosphate group of one nucleotide binds to the sugar group of the next nucleotide to form a long strand of nucleotides. Then the two strands of linked nucleotides are bound together and twisted around each other to form a spiral-shaped double helix. The sugars and phosphates form the outside “backbone” of the helix and the bases form the internal “rungs,” like steps on a twisting ladder. The bases are held together by hydrogen bonds. There are four different possible nucleotide bases that make up these “rungs:” adenine (A), thymine (T), guanine (G), and cytosine (C). In DNA, these four nucleotide bases are repeated over and over, billions of times, in different combinations. With the exception of identical twins, no two people share exactly the same order of DNA nucleotides.

Materials: Ziplock bag, strainer or funnel, jar or cup that fits strainer or funnel, coffee filter, 1oz shampoo, 1 tbsp. salt, 1 c. water, kiwifruit (peeled and cut into pieces), 2 tbsp. of isopropyl alcohol (rubbing alcohol), small tube.
