Presenters Frankie and Louise are enjoying the sunshine and put some sun cream on to protect their skin from the sun’s harmful UV rays.

Activity 1: An introduction to UV protection

Instead of using your skin as a UV detector, do a test with simple white beads to see if the sunscreen you are using is effective.

Investigate physiological mechanisms that allow the integumentary, skeletal, and muscular systems to function. What is the purpose of an experimental control? Give one specific example of a control used in this experiment. Do not look directly towards UV lamps. Turn on the UV lamps only when required, and after safety instructions have been given by teachers. Procedure Experimental setup for activity 3 Encourage students to stay safe in the sun with a collection of activities to discover the science behind sunscreen. Popular protocols for single cell genomics release barcodes from beads to increase availability for reverse transcription or PCR priming. This is normally achieved using UV cleavable chemical moieties, like 2-nitrobenzyl, or disulfides that can be broken with a reducing agent 2, 25. While fast to cleave, these linkers are expensive (Table 1) and require care to avoid premature cleavage during bead fabrication and handling. Our protocol instead employs enzymatic cleavage, yielding significant cost savings while also making the approach less sensitive to premature cleavage. Because genomic DNA is a valuable substrate in many single cell experiments, we avoid restriction enzymes including rare cutting Type IIS enzymes. Thus, we incorporate deoxyribose uracil (dU) as the linker, which does not exist in genomic DNA and can be cleaved by an enzyme mix comprising uracil DNA glycosylase and endonuclease III. Oligos containing dU are readily synthesized and inexpensive, and the linker consumes just one base. Moreover, dU containing oligos are stable and specifically cleavable by these enzymes, which are also readily available and inexpensive.

4: Detection and Absorption of Ultraviolet Light (Experiment)

Place four UV beads in the centre of a petri dish. Position the UV lamp approximately 20 cm away from the dish, or clamp a UV torch to a stand positioned at the same distance. Ensure that the UV light source stays at the same distance throughout the experiment and that the light always illuminates downwards. Mazutis, L. et al. Single-cell analysis and sorting using droplet-based microfluidics. Nat. Protoc. 8, 54–56 (2013). Basal cell carcinoma is the least fatal of the three, with 99% of people surviving if the cancer is treated. In basal cell carcinoma, shiny lesions appear, typically on the face. In this type of cancer, stratum basale cells lose the ability to form keratin and the boundary between the epidermis and dermis is not observed. This occurs slowly, which is why treatment is typically successful. Repeat steps 3–8 two more times (the beads can be reused many times). This will show that your results are reproducible.These short film clips support teachers with practical enquiry. They can be both used as a resource for learners to watch at home, or as a stimulus to support learners to plan and conduct their own science investigations. They link to the UK Science curricula. Place on a tray: control and experiment bags from Part A and one of each of the materials from the front bench (clear plastic, opaque plastic, sunglasses, glass plate, foil and cloth). Take the tray outside to an area of direct sunlight. or higher means extreme risk of harm from unprotected sun exposure. Try to avoid sun exposure during midday hours, from 10 AM to 4 PM. Apply sunscreen with an SPF of at least 15 liberally every two hours. Melsted, P., Ntranos, V. & Pachter, L. The barcode, UMI, set format and BUStools.
