How to get kids to love science

Maybe your kids already love science. If so, great! If not, these creative strategies can help. Ready to spark a love of science in the students near you? Here are five ways to get started. Encourage students to pick one action from the list below and try it out.

**1. Upgrade the science fair project.** Before you create that foaming tabletop volcano, check out these curiosity-powered experiments from Make, the Exploratorium, and mad scientist Grant Thompson. Which one will you try next? Science fair optional.

**2. Join the citizen science brigade.** ”Citizen scientists” are volunteers who help to collect and analyze research data in fields ranging from archaeology to zoology. Explore citizen science project options here, here, and here.

**3. Invent a solution to a real-world problem.** In Kenya, student Richard Turere invented a solar-powered way to prevent lion attacks. In Malawi, a young William Kamkwamba harnessed the wind to power his family’s home. In Hong Kong, students in Cesar Harada‘s class work together to address environmental threats to the ocean. Now it’s your turn. What problem do you care about enough to solve — and how will you do it? To filter options quickly, try the Google Science Fair’s Make Better Generator.

**4. Research quirky, open-ended questions**. Science is the story of humans asking ”why?” “how?” and “what if?” about what they observe. What questions will you ask of the world? To get inspired, check out these questions no one knows the answer to (yet).

**5. Explore science fiction**. Futurists believe that science fiction can predict the future — or at least provide us with a way to imagine and prototype the future. Do you agree? Before you decide, read one of the short sci-fi excerpts shared here, or watch a video from the Superhero Science series.

Calaria does a science

pictures from the Exploratorium in SF for the next week or so. :)

had some postcards i couldn’t frame yet so i put them in a safe place

guess what i have not found after turning the house upside-down

*Pi has been known for almost 4000 years—but even if we calculated the number of seconds in those 4000 years and calculated pi to that number of places, we would still only be approximating its actual value.*

Here’s a brief history of finding pi:

The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for pi, which is a closer approximation.

The *Rhind Papyrus* (ca.1650 BC) gives us insight into the mathematics of ancient Egypt. The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for pi.

The first calculation of pi was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world. Archimedes approximated the area of a circle by using the Pythagorean Theorem to find the areas of two regular polygons: the polygon inscribed within the circle and the polygon within which the circle was circumscribed. Since the actual area of the circle lies between the areas of the inscribed and circumscribed polygons, the areas of the polygons gave upper and lower bounds for the area of the circle. Archimedes knew that he had not found the value of pi but only an approximation within those limits. In this way, Archimedes showed that pi is between 3 1/7 and 3 10/71.

A similar approach was used by Zu Chongzhi (429–501), a brilliant Chinese mathematician and astronomer. Zu Chongzhi would not have been familiar with Archimedes’ method—but because his book has been lost, little is known of his work. He calculated the value of the ratio of the circumference of a circle to its diameter to be 355/113. To compute this accuracy for pi, he must have started with an inscribed regular *24,576-gon* and performed lengthy calculations involving hundreds of square roots carried out to 9 decimal places.

Mathematicians began using the Greek letter π in the 1700s. Introduced by William Jones in 1706, use of the symbol was popularized by Leonhard Euler, who adopted it in 1737.

An Eighteenth century French mathematician named Georges Buffon devised a way to calculate pi based on probability. You can try it yourself at the Exploratorium’s Pi Toss exhibit.

Kaela makes some patterns

happy little bean goes to an art museum!!!

Took a selfie with Michael Cera today! He was on a date with his girlfriend at the ExplOratorium in San Francisco! michaelcera
