Simple Bridges from Ancient Times

Simple Bridges from Ancient Times

Bridges are not easy to construct. With all of the different types of support, it is important to pick the correct one for the area. Let's start with some paper models to get an idea of which bridge is the strongest.

Build a Craft Stick Catapult

Build a Craft Stick Catapult

From Engines!

Ancient armies used catapults in battle. But the catapult has been used as recently as World War I. In that war, soldiers used catapults to toss hand grenades at the enemy. Today, catapults are used to launch planes off the decks of huge ships called aircraft carriers. Because the runway is short on an aircraft carrier, the catapult helps get the plane into the air quickly. Try making your own!

Design a Poll

Design a Poll

From Big Data

Often, data is collected using a poll or survey. A poll or survey asks questions about people’s opinion on a topic. In this activity, you will design and conduct your own poll.

Take a Turing Test

Take a Turing Test

From Artificial Intelligence

In 1950, an English computer scientist named Alan Turing (1912–1954) devised a test to tell a person from a computer. You’re going to try this with a Chatbot. This is an online computer program that is designed to mimic a human.

Observing Forces Of Motion

Observing Forces Of Motion

From Projectile Science

When something moves, a lot is going on that we don’t see. But we can make deductions based on our observations of different movements! Try moving different objects on different surfaces and see what you learn.



CLEAR Review (Clermont County Public library)
