Titrations are pHun
Properties of acids, bases and the pH scale are core concepts in any chemistry class. After your students understand the basics, it is important for them to be able to quantify reactions involving acids and bases with a titration.A...
Transpiration with a Potometer
Transpiration is an important concept in both biology and environmental science, especially in terms of role it plays in the water cycle. As water evaporates from the stoma of leaves water is pulled up (due to hydrogen bonding)...
Temperature misconceptions? Shake it off.
Most students understand that things get warmer as temperature goes up, but it is in the science lab that we have an opportunity to really help them understand what temperature means. One of the core ideas in Physical Science...
pH Imbalance - Getting to the Root of the Problem
Science is more meaningful and engaging when students have the opportunity to explore the world around them. And it is more meaningful still when students are empowered with the tools to collect and analyze data just like...
Chemistry in a Cuppa
Every January educators from across the UK gather for the Bett conference to learn about innovative ways to use technology in education. This year this lucky chemist had the opportunity to travel across the pond to London...
Working for a Winter Wonderland
Instant snow is a fun substance for kids of all ages and a great tool for engaging young scientists in physical science concepts related to matter and its interactions. And the new Wireless Temperature Sensor helps to make...
Under Pressure - Wireless Sensor Inside a Balloon!
When introducing pressure and gas laws, I have always used balloons as a conceptual starting point because they are a familiar item to students. Unfortunately, I could not easily measure the actual pressure inside of the...
An Open Bottle for Inquiry on New Year's
It’s New Year’s Eve, and with any luck, soon the music and Champagne bottles will be poppin’. Not only it is an opportunity to raise a glass in toast, it is also raises an interesting science question:How can we measure...
