Look at these three puzzles on the board. How would you send a message across the room without speaking? How would you lift something heavy with less effort? How would you stop an ice cube melting?
People in Ireland once faced problems just like these. Today we will try to crack them ourselves.
Every big change in how we live started as someone trying to solve a problem with what they had, just like you will at the trays.
Today's words: STEM: Science, Technology, Engineering and Maths working together to solve real problems. Engineering challenge: a problem you try to solve with limited materials and a clear goal.
Look back at our three puzzles on the board. Which puzzle are you most excited to crack, and why?
Your group will visit three stations. At each one, read the challenge card, use only the kit on the tray, and try to crack the problem.
At every station: try, agree what worked, jot one short note on your journal page, tidy on the signal. You have about seven minutes at each stop, including tidy and move. Be ready to tell the class later what idea worked and why you think it worked.
Open your Investigation Journal page. You already jotted at each station. Now make sure all three challenges are clear.
For each station use these stems: Idea that worked… and I noticed… Add a short I think… only if you have time.
Each group will share one station only, in one short sentence: name the challenge, the idea that worked, and one thing you noticed. Listen for ideas your group did not try.
