Tell your students that today they are going to learn a new word. Tell them the new word is “hypothesis” and ask the students to repeat the word back to you. Write the word hypothesis on the board or on a flip chart to reinforce word and letter recognition. Ask your students if anyone knows what the word hypothesis means (accept all answers).
Tell the children they will watch a clip from Dinosaur Train. Ask the children to listen for Buddy the T.rex’s definition for the word hypothesis.
What did Buddy and Tiny say a hypothesis is? (An idea that you can test).
