**This is a great outdoor activity for kids to learn about the change of seasons and the natural environment around them. ** The free printable activity sheets are provided for children aged 5 to 14. There is a wide variety of wildlife and plant life for kids to spot while wandering through the woodland or countryside looking for items to match the pictures. Along with the pictures, there are science questions and ideas for children to think about. This scavenger hunt helps children develop their scientific knowledge by encouraging them to observe and identify different species of plants, animals, and insects. This can help students learn about ecosystems, food chains, and animal adaptations, among other topics. It promotes gentle physical activity and fitness by encouraging children to walk while searching for items on their lists. It will give children the opportunity to learn about the science of winter, including animal adaptations, weather patterns, and seasonal changes. They are also a great way of fostering a sense of teamwork and collaboration as kids work together to find and collect all the items. The science context Winter scavenger hunts can create engaging and interactive learning experiences that encourage curiosity, observation skills, critical thinking, and a deeper understanding of scientific concepts. It allows children to become active participants in their own learning, igniting their passion for science and cultivating the next generation of scientific thinkers. Suggested learning outcomes By the end of the activity, kids will have gained a deeper appreciation for the natural world and the role that science plays in understanding it. The activity can also help to teach geography lessons by encouraging kids to explore different landscapes and geographical features, such as rocks and bodies of water. We have a choice of three different winter scavenger hunt games for you to download, for 3-6, 5-11 and 11-14 year olds. Each game asks a series of questions, so there is also a corresponding answer sheet to download. Make sure the participants wrap up warm! Going for a walk on or around Christmas? Please do share your pictures of what you find on your winter scavenger hunts with us on social media on Facebook and Twitter using our #SantaLovesSTEM hashtag. You can also send them via email to IETEducation@theiet.org to be featured in our online gallery.

Learn about simple mechanisms and make an animal that moves in this fun and creative activity for kids! Students will use templates to help them cut out the parts for a DIY cardboard animal, and they will make the parts of a simple mechanism using cams and linkages, which will be attached to a round shaft made from a skewer; This will allow the legs of the animal to move up and down slowly. This activity could be used as a main lesson activity to teach learners about simple mechanisms and how the direction of motion can change from rotary to reciprocating. This is one of a series of free STEM resources designed to support the delivery of key topics within science and design and technology, which could be carried out individually or in pairs. The teacher presentation could be left on the whiteboard as a supporting guide as they do this. Learners may need assistance cutting the cardboard to ensure the cuts are accurate. As an optional extension activity, learners could add their own designs to their animal’s body and legs. Keeping the white paper template stuck to the legs allows them to be decorated as desired. Tools/resources required Card tubes Wooden skewers Glue sticks/ glue sticky tack Cardboard Brass split pin fasteners The engineering context Mechanisms are used in almost every moving product, ranging from trains and cars to washing machines and door handles that must be pushed down to open, see-saws and scissors. They either transmit motion or change it in some way, increasing or decreasing its strength, quality, or type. Suggested learning outcomes By the end of this activity, students will be able to understand that a linkage and cam can create movement, they will be able to make an amazing animal from graphics materials, and they will be able to use cams and linkage to make the legs move on the amazing animal.
