Students are challenged to design the strongest table that they can using the least amount of materials and money. They are given one roll of masking tape and can purchase newspaper sheets at a cost of $5.00 per sheet (a double page spread). They are not allowed to purchase tape, so it must be used wisely! Newspaper and tape are the only materials that are to be used. The table will be evaluated on various criteria, including meeting the design criteria, appearance, design efficiency, and cost efficiency.
Why is there something rather than nothing? Why does so much interesting stuff exist in the universe? Particle physicist Harry Cliff works on the Large Hadron Collider at CERN, and he has some potentially bad news for people who seek answers to these questions. Despite the best efforts of scientists (and the help of the biggest machine on the planet), we may never be able to explain all the weird features of nature. Is this the end of physics? Learn more in this fascinating talk about the latest research into the secret structure of the universe.

In this activity, students will observe how the stem of a plant carries water and nutrients. The stem of a plant contains small tubes which extend from the roots to its other parts. Water and nutrients travel between the roots and the plant’s other parts using this system of tubes.
