Design Technology - STEM Activities


Due to how much you all seemed to enjoy the roller​​​​​​coaster building activity last week, we've got 4 new practical activities for you to have a go at this week. Remember to let us know how you get on.


Monday 18th May:

Task 1: Egg Drop Challenge
☼ Your task is to design and make a container that will stop an egg getting smashed when dropped from a height onto a hard surface (the higher the better, but make sure you're safe).
☼ Start by downloading the Egg Drop Challenge Design Sheet (available below) and design a container to keep your egg safe.

☼ Build your container by following your design, and place the egg inside.
☼ Find a good high spot to drop your egg from (make sure an adult supervises you for this bit), and drop your container with the egg inside.

☼ Now it's time to find out if your cracked survived the fall: did it crack or remain intact? (If it cracked, remember to wash your hands after touching raw egg.)

☼ Optional: download and complete the Egg Drop Recording Sheet. It might be fun for you to get your family involved, and see who can make the best container. Use the sheet to record your results.


Tuesday 19th May:

Task 1: Rainbow Jars and/or Lava Lamps

Today you can choose whether to create a rainbow jar or a lava lamp (or if you're feeling inspired, both!)
☼ Rainbow Jars:

☼ Lava Lamp:

  • You will need a tall, transparent container; some water; some oil; an effervescent tablet (e.g. Alka-Seltzer, Berocca); and food colouring.
  • Download the Lava Lamp Activity Sheet below and follow the instructions.


Thursday 21st May:

Task 1: Create a Rube Goldberg machine
☼ I'm sure you've seen these, even if you don't know it. Those machines which involve a long, overly-complicated chain reaction of processes that lead to completing a simple final task in an indirect way. 

☼ Here are some well-known examples:

☼ There are probably thousands more (including one that's over 30 minutes long and every domino run ever made). But don't worry, you don't need to start this complicated. Why don't you start by trying to make a chain reaction of three things?

☼ The great thing about trying something like this is that you can use anything you can possibly think of around your home. Most Rube Goldberg machines are created using every day items, and capitalise on energy stores and energy transfers (this is something you could research more about).

☼ Start by thinking of a simple action (like turning a switch on/off, turning a page, changing the channel on the television), and work backwards from there. Aim for a chain of three, but don't limit yourself - we would love to see some really convoluted machines with lots of steps.

☼ Take a picture, and/or a video, and email us your creations!

☼ (There's loads of information and ideas online if you want to find out more or need a little more inspiration - use your research skills to find out more.)


☺ Good luck!! ☺
