Over the years, i took in NT students. But sadly, i couldnt find any resources for them to practice. So sad.

So over the years, i come up with questions for them. I decided to continue to do more resources for these group of students. Maybe one day, i can published my own NT science book. 🙂

This is one example of one worksheet. Decided to post this after one of my student told me her friend also want some questions to practice.

- The electrical appliances X and Y are marked 100W and 125W. If they are turned on the same amount of time, which appliance consumes less energy? Explain your answer.

Could I have the answers to the above questions

Hi Kamini, can you leave your email? I will send the picture solutions to u as it will take a long time for me to key everything here. Thanks.

Hello. Do you still have the answer key? Do you mind emailing it to me at xiaogua130111@hotmail.com?
