Word Sheet
There are lots of new key terms that you need to make sure you understand. It’s really important
that you recognise what each of the words mean and are able to use them correctly in a sentence.
This will help you to explain ideas scientifically and ensure you pick up important marks in your
assessed pieces of work and exams.
Some tips for learning science vocabulary:
Tip 1 -Play some games with the keywords
You could play hangman with your friends or family using the words you need to learn. Make sure
you explain what the word means when they have guessed it.
You could play Pictionary for some of the energy types or renewable energy sources. Ask someone
to draw you a picture for one of these terms and see if you can guess which one they are drawing.
You could make a puzzle such as a crossword or a key word wordsearch

Tip 2 – Use flash cards
Write out the key word and the definition on separate cards, mix them up and see if you can match
the keyword with the correct description.
Write the keyword on one side and the definition on the other. Look at the keyword side and see if
you can remember the definition or read the definition and try to remember the keyword. Turn the
card over to check, or ask someone else to read them out to you.
See if you can sort the keywords into groups of similar words. For example, you could group together
all the words that give a different type of energy. Try to explain why you have grouped them
together to a friend or family member.
Tip 3 – Spelling strategies

difficult to spell.
