Chemapalooza 6-22: Ooey Gooey

Chemapalooza 6-22: Ooey Gooey

Silly slime and smiling faces! Students became Chemical Polymer Interns for Ooey Gooey Toy Company today. While creating their own Play Doh, Putty, Goo, and Oobleck substances, our interns learned about polymers and heterogeneous mixtures. They used that knowledge to make a new toy for the company, a bouncy ball, by using the ingredients from the previous slimes.

Ask your student: What type of substance is Play Doh? (Suspension) What kind of molecules are in Putty and Goo? (Polymers) What substance gives Goo its sliminess? (Borax)

Chemapalooza 6/21: Water Beads

Chemapalooza 6/21: Water Beads

Today, in Chemapalooza, the students investigated the nature of water beads. Our little chemists used the scientific method to design their own experiment and create a hypothesis on how they predict different liquids or different concentrations of liquids would have an impact on the growth-size of water beads. As the week progresses, the students will continue to work through the experiment and analyze their results and ultimately evaluate their hypothesis.

Ask your student:

What is osmosis? (Osmosis is a special type of diffusion- movement of water across a barrier form high to low concentration)

What is an independent variable? (An independent variable is the variable you are testing in an experiment: it is the variable that is changed)

Game Day STEM 6/22: Egghead Day 1

Game Day STEM 6/22: Egghead Day 1

Today, in Game Day STEM, the students used a “Free Fall Impact Tester” to test how well specific materials protect a hard-boiled egg from a free falling object. The goal of the activity was to simulate how well different materials used in helmets protect the head from impact all while learning about free fall distance and velocity.

Ask your student: What is the relationship between the height of a dropped object and the velocity with which the object is traveling? (The higher the height the object is dropped from, the greater the velocity. There is a direct relationship between height and velocity)

Game Day STEM 6/21: Pole Vaulting!

Game Day STEM 6/21: Pole Vaulting!

Today, students continued to explore the important role that physics plays in sports.  They also investigated how potential and kinetic energy plays a role in pole vaulting. After collecting data, students hypothesized the optimal conditions for a vault, and using an online simulation, they were able to test some of these hypotheses by changing various factors that affect pole vaulting (speed of vaulter, height of bar, etc.).

Ask your student: Is there an optimal amount of flexibility in the pole that would be best for the vaulter? Which factor had the biggest effect on whether or not the vaulter cleared the bar?

Game Day STEM 6/20: What’s Your Vertical?

Game Day STEM 6/20: What’s Your Vertical?

Today students tested to see how the position of your body affects the way it moves. After selecting a few different angles, the students precisely measured the flexion of their knee, and then measured how high they could jump!

Ask your student: What angle helped you to jump the highest?

Chemapalooza – 6/20: Magic Messages and Liquid Nitrogen Ice Cream!

Chemapalooza – 6/20: Magic Messages and Liquid Nitrogen Ice Cream!

Today, students became chemical investigators to discover the concepts of pH and acids/bases.Our junior chemical scientists observed color changes during reactions using common household materials. Students also wrote invisible messages to friends!

Ask your student: What are examples of acidic liquids? What are examples of basic liquids? (Acidic: tomato juice, acid rain, battery fluid; Basic: milk, eggs, soapy water)

Game Day STEM – 6/19: Splash Science

Game Day STEM – 6/19: Splash Science

To start off the week, in one of their lessons the students investigated splash. They experimented with different variables in order to hypothesize what is necessary for divers to enter the water with minimal splash. Students generated an investigable question, developed a procedure to test their question, and analyzed the results of their experiment.

While testing their hypothesis students dropped many different weighted objects at different heights into the water to see what was different in the splash.

A question to ask your student: What was your investigable question(s)? (various answers)

What splash do you think this will create? The young scientists are coming up with “testable” questions about how the height, angle of entry, and shape of an object will affect its splash.

The students are “gearing up” for cycling science! Those nifty purple items are gear kits that allow the students to figure out how to manipulate gear ratio for better performance.

Chemapalooza – 6/19: Molecular Gastronomy

Chemapalooza – 6/19: Molecular Gastronomy

Today students trained to become a budding chef in an emerging culinary style known as Molecular Gastronomy. Exploring how science and art can mix, students used the scientific principles of Molecular Gastronomy to create visually appealing and texturally unique foods, and explored two foodie experiments. By the end of the lesson, students became quite knowledgeable in the growing field!

Ask your student:

What is the process of thickening a liquid so it doesn’t melt in its new solid form? (Gelification)

What is the process of creating gelified pearls? (Spherification)

 

Micro STEM

Micro STEM

Did you know that some of the smallest things in our universe are also some of the most powerful?

From microwaves, to molecules, to circuits and code, this program will take a hands-on approach to exploring the STEM of tiny things.

Students will gain a greater understanding of the small underpinnings of everything around us. What’s behind the flip of a switch? What is life made of?  How can we make sense of the things we can’t see?

This program will harness the power of smartphones and innovative scope lenses to help students answer these questions and more!

Ever wonder about the math, engineering, and physics principles that are the foundation of sports?

Come to IMSA to examine the Science, Technology, Engineering and Math behind the many of the sports you know and love!

Students will design, build, and race a robotic swimmer, re-engineer an archer’s bow, test cycling tires and gears, and more!

Participants will leave with an understanding of how STEM concepts are harnessed to help athletes maximize their performance.
