What stores and transfers energy?
Energy cannot be created or destroyed, it can only be transferred from one store into another. In these pictures, which items do you think use energy? Which ones store energy? Do they all store/use the same type of energy? Cut them out and sort them into groups.
Understanding friction: Build your own balloon hovercraft
When a moving surface slides on a stationary surface it rubs against it, which slows it down. This is due to friction, a force which resists the movement of one object sliding past another. Understand more about friction with a fantastic practical project: make your own balloon hovercraft!
Super scientist quiz
Quiz questions to encourage your child to think about how scientists work and why they do the things they do.
Reaching conclusions
A worksheet showing results of an experiment with questions underneath to consider.
Writing simple, compound and complex sentences
Look at each of the following pictures. Can you write a simple, compound and complex sentence to go with each one?
Writing main clauses
A main clause can stand on its own and make complete sense. It is a simple sentence. A subordinate clause depends on the main clause to make sense. The following sentences are all missing their main clauses. Can you write them in where you think they should go?
Using adverbs to connect clauses
A subordinate clause contains a subject and a verb, but it needs to be attached to a main clause because it cannot make sense on its own. Clauses can be linked by conjunctions, prepositions and adverbs. Adverbs are used to show sequence (eventually, finally, meanwhile), contrast (however, on the other hand) or cause and effect (therefore, subsequently). Which of the red adverbs from inside the brackets above would fit into the sentences below?
Synonyms in a non-fiction text
Synonyms are words that have similar meaning. When we write a non-fiction text, we often need to use synonyms so that we do not keep repeating the same word. Read through this passage. Every underlined word can be paired a synonym (also underlined) in the text. Can you find all the pairs of synonyms?
Synonym or antonym?
Synonyms are words that have similar meaning; antonyms are words with opposite meanings. Each of the following sentences contains either a pair of synonyms or a pair of antonyms. Underline each pair of words and then write in the box beside it whether they are synonyms or antonyms.
Superlative adjectives
Adjectives have three forms: positive, comparative and superlative. The comparative is used to compare one person or thing to another. The superlative form is used to compare one thing to all the others like it. Look at these sentences. Can you change the word in the box to its superlative form?
Subordinating conjunctions
A subordinating conjunction introduces a subordinate clause (a clause that does not make sense on its own). Can you put each of these conjunctions into the gaps in the sentences below?
Simple, compound or complex sentence?
A simple sentence consists of just one clause. A compound sentence consists of two main clauses of equal weight joined by a conjunction. A complex sentence is made up of a main clause and one or more subordinate clauses. Conjunctions such as because, although, until are usually used to link the subordinate clauses to the main clause. Look at these sentences. Can you tick the right-hand column to show whether they are simple, compound or complex?
Simple past or past perfect?
The past perfect is a verb tense that is used to describe an action that has occurred before another action in the past. Cut out these sentences. Which ones include verbs in the past perfect?
Past perfect: writing your own sentences
The past perfect is a verb tense used to describe an action that has occurred before another action in the past. Look at these pairs of sentences. Can you rewrite each one as a sentence that contains both the past perfect and the simple past tense?
Past perfect: matching halves of sentences
The past perfect tense is used to describe an action that has occurred before another action in the past. Cut out these halves of sentences. Can you work out which past perfect tense first half should go with which past tense second half?
Past perfect: completing sentences
We use the past perfect to talk about an action that occurred before another action in the past. Can you write your own sentences in the past perfect?
Pairs of synonyms
Synonyms are words that have similar meaning. For example: ‘overjoyed’ is a synonym for ‘happy’. Cut out the following words. Can you match up the pairs of synonyms?
Matching up main and subordinate clauses
A clause is a group of words that contains a subject and a verb (a doing word). A main clause makes sense on its own. A subordinate clause is dependent on a main clause and does not make sense on its own. Cut out the (blue) main clauses, the (orange) conjunctions and the (purple) subordinate clauses. Match them up to make six sentences that make sense.
Linking clauses with adverbs
Conjunctive adverbs connect one clause to another. They are used to show sequence (eventually, finally,meanwhile), contrast (however, on the other hand) or cause and effect (therefore, subsequently). Can you finish the sentences below by writing a subordinate clause to add to the main clause and adverb given?
Joining sentences with conjunctions
We link main clauses (which make sense on their own) and subordinate clauses (which depend on the main clause) using connectives. Connectives that join clauses can be conjunctions, prepositions and adverbs. Below is a main clause (in blue) followed by conjunctions (in orange). Can you complete each sentence with your own subordinate clauses?
Identifying simple, compound and complex sentences
Can you identify if these sentences are simple, compound or complex?
Identifying past perfect sentences
Verb tenses tell us when an action took place. The past perfect tense is used to describe an action that has occurred before another action in the past. Look at the following sentences. Can you underline the verbs that are in the past perfect?
Identifying main and subordinate clauses
A clause is a part of a sentence that contains a verb. A subordinate clause is one that is dependent on a main clause and does not make sense on its own. We use connectives to join two clauses. Read these sentences. Can you underline the main clause in blue, the subordinate clause in red and the conjunction in green?
Forming the superlative
We use superlative adjectives to compare one thing to all the others in the same category. Look at the adjectives in the left-hand column. Can you write the superlative form on the right-hand side?
