My Subjects Science
Objectives
• Describe what forces can do
• Recall that forces can be contact on non-contact forces and be able to name some examples
• Explain the difference between mass and weight
• Describe what friction is
• Describe what balanced forces are
• Recall what balanced forces can do

Science

1 PRE-ASSESS KNOWLEDGE

Socrative
Free, Paid
• Create a quiz about forces with some specific questions addressing vocabulary such as mass, weight, gravity, force, air resistance, upthrust, thrust, force meter, balanced, non balanced, contact...
• Share Quiz: SOC-10074273
• Run the quiz and analyze the results to see the parts the students are familiar and the ones you need to reinforce the content through the unit
Student Instructions
• Join the room number and complete the quiz

2 LEARN

• Presentation about the different key words of the unit
• Diagrams to represent forces with examples
• Some clip videos and questions related to them
Student Instructions
• Students complete some worksheets after the presentation

3 HOOK

• Show the FORCES animation (or ask the students to watch it independetly)
• Ask students to do the quiz and activity (vocabulary)
• Run the game "Flight adventure's. Forces of flights"
Student Instructions
• Students complete the quiz and activity (vocabulary) after watching the animation
• Students try the game for 5-10min until they understand the reason why the planes can fly

4 APPLY

Free, Paid
Free, Paid
• Show the videos:
• After that students can get some ideas on how to build a simple parachute
Student Instructions
• Students receive instructions sheet and rubric and start to plan their design investigation (to make it more exciting for the kids, I make a challenge: they must save an egg inside the plastic ziplock bag, it means more time gliding for a softer landing, therefore they need to figure out how to design it..)
• Students do some research on ways to make parachutes
• Materials, to simplify and don't waste too much money on resources, stick to the video using:
• Plastic bags, strings, small ziplock plastic bags, sand/peebles, tape, ruler and scissors)

5 FEEDBACK

• Students submit the lab report through turnitin
• Using the tool mark on turnitin, I create the rubric and some comments link to the rubric to give them feedback
Student Instructions
• Students submit the work
• Students peer assess using turnitin (another tool from the platform) and a marking template (link to the rubric)
