In these 4 lectures, HHMI president and Nobel laureate Thomas R. Cech explains the role of RNA in cellular biology. He also discusses other implications of RNA catalysis. Lectures were given in 1995.
Double-slits and diffraction
This kit and their associated resources are designed to help teach about double-slit and diffraction patterns.
Before teaching this, students should:
- be familiar with constructive and destructive interference;
- be aware that we get diffraction when a wave travels through a gap;
- ...
Doubling and Dabbling in Duckweed
Produced by Science & Plants for Schools (SAPS), the investigations suggested in this resource use duckweeds. These seem to be simple plants - small, green, and with no flowers. However, this simplicity makes them ideal experimental organisms for investigations into...
An exciting and colourful resource to enhance and reinforce the understanding of basic mathematical calculations and number sense. Presents calculation problems and step-by-step guides that explain how to solve them...
