The document discusses key concepts about chemical reactions and equations including:
1. Chemical equations are used to represent chemical reactions, with reactants on the left side and products on the right side.
2. A reaction is endothermic if heat energy is absorbed, and exothermic if heat energy is released.
3. The law of conservation of matter states that the number and type of atoms is the same for both reactants and products, though they may be rearranged. Mass is also conserved in chemical reactions.
An attempt to make the description of chemical reactions a mini-story. Not the best story by any means, but it was pretty well received by the students.

Bead Loom Tutorial
Supplies used:
Standard Bead Loom
Beading Needle & Thread
Seed or Delica Beads
Scissors
Bead Loom Pattern
Instructions:
1. Measure out and cut a piece of beading thread the length of your loom, plus ling enough to wrap around the spools if if you are creating an applique that is longer than the distance between you loom's two springs.
2. Cut additional threads of the same length as the piece you measured out in Step 1. Cut 1 more piece than the number of beads per row on the pattern you are using. For example, if your pattern is 13 beads wide, then you would cut 14 pieces of thread.
Align your pieces of thread up next to each other.
Tie all of your threads together at either end of the group.
3. Split the group of threads into two slides, hooking the loom spools with either end of the group.
Wrap one side of the loom spool around until the groups of thread are tightly stretched across the loom.
4. Separate your threads evenly across the loom, placing 1 thread in-between each spring swirl.
Thread your needle with a much longer length of thread and tie the end of it with a small knot at the beginning of your loom work, a short distance from the right or left spring on the loom.
5. Thread your first row of beads onto your needle, according to your pattern.
Here we are demonstrating working from top-to-bottom for each row.
6. Separate your row of beads so that each individual bead fits between 2 of the threads on your loom, pressing them up with a finger from your other hand so that the holes of the beads are vertically above the threads on your loom.
7. Thread your needle back through the row of beads, keeping it on the upper-side of the threads on your loom.
Pull the row tight.
8. Repeat step 7 for the second row, adding your bead colors per your pattern.
9. Continue repeating step 7 down through the duration of your design.
If your design is longer than the distance between your loom's two springs, rotate your spools so that part of the design slide over the spring on one side, and more thread is allowed on the other side for beadwork.
10. tie and cut off your longer, beading thread. Remove your be loomed piece from the loom, and cut off the knot on the end, as close to the knot as you can to leave plenty of thread slack for finishing off the piece.
11. Thread one or two (that are next to each other) of the slack threads into your beading needle.
12. Weave your needle through one or more beads from within your applique.
Take another thread or two and weave them through, coming out of a bead next to or facing the first one or two added.
13. Tie the two sets of thread from step 12 together in a square knot.
Pull tight so that your knot becomes hidden within your beadwork.
14. Repeat steps 11 through 13 until you have finished off the remainder of your applique's side, and then repeat steps 10 through 14 on the other side of your applique.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
