“OK Google” for Math Quizzes
On Wednesday, Study.com announced access to hundreds of quiz questions in math and three other subject areas through the Google Assistant on phones or voice-activated speakers, like Google Home.
Just say, “OK Google, talk to Study.com” within range of a Google Assistant or Google Home, and the device will quiz you with a series of four multiple-choice questions.
So now instead of the Google Assistant answering questions, it will ask you!
With their parent’s permission, children under 13 can also have their own personalized Google Assistant experience when they log in to Google Family Link.
Study.com offers online courses and study tools to help students in kindergarten through college excel academically. Last summer, the company rolled out its first apps; this summer, Study.com received a $100,000 grant to expand its tuition-free college program.

Science Fair Season is upon us. Here are some ideas and great links
Inventors and inventions
About inventors and inventions through the ages. Also gives advice to would-be investors on patent applications etc.
This is a good technology website with background information on inventions from Adrenaline to the Zipper – and also some biographical detail on the inventors.
Science and mathematics encyclopaedia sites
This is the gateway to all of the wolfram.research reference sites including those on astronomy, biography, maths, music, paper sculpture, Star Trek and wine tasting!
Eric Weisstein’s World of Science is packed with good stuff – and improving daily. It is funded by Stephen Wolfram, one of the whizziest computer whizkids around.
Like his World of Science, Eric Weisstein’s MathWorld is chock full of interesting mathematics and material for teachers to use to promote interest in the subject.
(It appears that has been a legal action in the USA between the author of this site, Eric Weisstein, and a publishing company. The result of the action has been the temporary or permanent transfer – one cannot be sure yet which – of the “mathworld” site to something called “planetmaths” or “planetmath”. Search the web to ascertain this for yourself. Add the result to your “favourites”.)
Guidlines for projects
Guidelines for selecting suitable investigations
Some interesting science activities for kids to try at home. This keeps parents on their toes!

How to make a 3D hologram from your Cellphone or Tablet:
We chose to not use a CD cover and we wanted to make ours larger!!! We made our own design using overhead transparencies and we created this template.
You can also buy a cheap Pyramid template from the cheap store that folds into a pyramid and these worked for us too.
